  • 08:11K. Very good. Okay.
  • 08:13K. Welcome, everybody. We'll just
  • 08:14kinda kick things off.
  • 08:18Hi. And happy New Year.
  • 08:22Uh-huh.
  • 08:23Let's go here.
  • 08:25Just running through,
  • 08:26the upcoming schedule. Still kinda
  • 08:28working out a few kinks
  • 08:29on the upcoming month. Doctor
  • 08:31Adiran will be speaking to
  • 08:32us, on the new guidelines
  • 08:34and then some faculty research
  • 08:36meetings, and then Miles Shen
  • 08:37will be doing a structural
  • 08:38case conference.
  • 08:40And then we'll get out
  • 08:41as we finalize these last
  • 08:42few details of spring semester,
  • 08:43we'll also get out the
  • 08:44whole semester schedule so you
  • 08:46guys have a heads up
  • 08:47and then can plan accordingly.
  • 08:49And then I will hand
  • 08:50things off to doctor Fau
  • 08:51who will introduce doctor Khan.
  • 08:53Thank you.
  • 09:01Thanks, Katherine.
  • 09:02It's my great pleasure
  • 09:04to introduce doctor Ali Khan
  • 09:06as today's cardiovascular medicine grand
  • 09:08round speaker.
  • 09:10Ali is a native of
  • 09:11Virginia and did his undergraduate
  • 09:13work at the University of
  • 09:14Virginia where he was a
  • 09:15chemistry major, which I was
  • 09:17quite surprised
  • 09:18to find out.
  • 09:19Not surprisingly,
  • 09:20he won the Merck Award
  • 09:22for being the top chemistry
  • 09:24student
  • 09:25in the undergrad program there.
  • 09:27He also won a teaching
  • 09:29award for undergraduate chemistry.
  • 09:32He stayed at the University
  • 09:33of Virginia to do his
  • 09:35MD PhD
  • 09:36work
  • 09:38as a PhD student. His
  • 09:40work focused on the structure
  • 09:41of gap junction channels
  • 09:43in the context of myocardial
  • 09:45infarction.
  • 09:47He then, came to Yale
  • 09:49for his internal medicine residency,
  • 09:51where he worked with Rachel
  • 09:53Lampert looking at the effects
  • 09:55of atrial fibrillation and atrial
  • 09:56fibrillation treatments
  • 09:58on athlete performance.
  • 10:00And then, of course, he
  • 10:01stayed for his cardiology fellowship.
  • 10:04And interestingly,
  • 10:06is working with, Joel Butterwick
  • 10:08from the Department of Pharmacology
  • 10:11on the molecular structure
  • 10:13of this is hard for
  • 10:15me as an interventionist to
  • 10:16say. Okay?
  • 10:17Human cardiac rapid delayed rectifier
  • 10:20potassium channels
  • 10:22bound to class three antiarrhythmics
  • 10:25to understand,
  • 10:26the functional effects of antiarrhythmics
  • 10:28and perhaps
  • 10:29to design antiarrhythmics
  • 10:31as well.
  • 10:32So,
  • 10:33without further ado, Ali, thank
  • 10:35you very much, and we're
  • 10:36looking forward to your discussion.
  • 10:51Thanks, doctor Pha, for that
  • 10:52kind introduction. Thank you for
  • 10:54everyone
  • 10:55attending our clinical grand rounds
  • 10:57case presentation.
  • 10:58Today, our case comes from
  • 10:59the Connecticut VA health care
  • 11:01system.
  • 11:03I'll be presenting a real
  • 11:05really interesting and
  • 11:07unusual case of an enlarging
  • 11:09left ventricular aneurysm.
  • 11:11In addition, we're also gonna
  • 11:13have,
  • 11:14experts joining us today, which
  • 11:15will also be teaching us
  • 11:17on the various nuances
  • 11:18in terms of the imaging,
  • 11:20and we'll also discuss surgical
  • 11:21management.
  • 11:23Our learning objectives today include
  • 11:26to review the imaging findings
  • 11:29of LV apical aneurysms with
  • 11:31echo CT and MRI.
  • 11:33We'll also discuss the management,
  • 11:36and discuss the management of
  • 11:37LV aneurysms.
  • 11:41Now this is a case
  • 11:41that spans a little over
  • 11:43two and a half years.
  • 11:44So to orient everyone to
  • 11:45the presentation,
  • 11:46I'll be focusing on three
  • 11:48periods. First, the initial hospitalization,
  • 11:51then the outpatient management, which
  • 11:53was primarily in the VA
  • 11:54system, and then surgical management,
  • 11:56which was a joint effort
  • 11:57between the West Haven VA
  • 11:59and Yale New Haven Hospital.
  • 12:04So our case,
  • 12:06goes to February twenty twenty
  • 12:07three.
  • 12:08This our patient is a
  • 12:09sixty six year old female
  • 12:10veteran
  • 12:11with a three day history
  • 12:13of fatigue and unwitnessed fall
  • 12:15and also with chest pain
  • 12:16two days prior who presented
  • 12:18as an EMS STEMI activation
  • 12:20from an outside hospital.
  • 12:22Her past medical history has
  • 12:24multiple cardiovascular risk factors, including
  • 12:26diabetes, hyperlipidemia,
  • 12:28chronic kidney disease, and active
  • 12:29smoking,
  • 12:31as well as,
  • 12:34pulmonary nodules, bipolar disorder, and
  • 12:36PTSD.
  • 12:36She does not have any
  • 12:38prior cardiac surgeries nor does
  • 12:39she have a family history
  • 12:40of heart disease at baseline.
  • 12:42She's an she's independent and
  • 12:44able to perform all of
  • 12:45her ADLs.
  • 12:47This is her presenting EKG,
  • 12:51which shows ST elevations into
  • 12:53anterolateral
  • 12:53inferior leads
  • 12:55suggestive
  • 12:56of an extensive infarct.
  • 13:00Her physical exam was significant
  • 13:02for Raul's
  • 13:04and weak peripheral pulses. She
  • 13:05was hypotensive,
  • 13:06requiring presser support. Her initial
  • 13:08laboratory workup showed markedly elevated
  • 13:11high sensitivity troponins,
  • 13:13elevate BNP, lactic acid, AST,
  • 13:16and acute
  • 13:17kidney injury all concerning for
  • 13:19cardiogenic shock. In addition, in
  • 13:22the emergency room, she had
  • 13:23a point of care ultrasound
  • 13:24that showed severe apical a
  • 13:26kinesis and possible thrombus
  • 13:28at the LV apex.
  • 13:31The cath lab was activated.
  • 13:32Here's a coronary angiogram
  • 13:35of the left coronary arteries
  • 13:37system.
  • 13:38And,
  • 13:41and I want you to
  • 13:41appreciate that she had total
  • 13:43occlusion of the proximal left
  • 13:44anterior descending artery.
  • 13:47Here's now a a caudal
  • 13:49shot of the left system,
  • 13:50which, you can appreciate it
  • 13:52a little better.
  • 13:55And, again, seeing that where
  • 13:57there should be a branch
  • 13:58for the left anterior descending
  • 13:59artery is a big occlusion.
  • 14:04There's no significant stenosis in
  • 14:06any other vessel.
  • 14:09She also had no collateral
  • 14:10flow coming to this region,
  • 14:12this region of the heart.
  • 14:14The interventionalist
  • 14:15at the outside hospital
  • 14:17attempted balloon angioplasty,
  • 14:19but were unsuccessful.
  • 14:21She
  • 14:22had an intra aortic balloon
  • 14:23pump that was placed, and
  • 14:24then she was transferred here
  • 14:25to Yale.
  • 14:29For NPA, she was admitted
  • 14:30to the cardiothoracic ICU service
  • 14:31on pressors
  • 14:32and evaluated by our heart
  • 14:34failure team for advanced therapies.
  • 14:36She had a Swan Ganz
  • 14:37catheter placed, a mixed venous
  • 14:39o two saturation,
  • 14:41was in the normal race
  • 14:42likely corresponding to a missed
  • 14:44cardiogenic and distributed shock picture.
  • 14:48Her initial echo showed an
  • 14:51estimated ejection fraction of thirty
  • 14:53five percent
  • 14:55with apical a and anterior
  • 14:56a kinesis consistent with her
  • 14:58LAD infarct and a large
  • 14:59mural thrombus measuring three point
  • 15:01one by one point two
  • 15:02centimeters.
  • 15:05She had a fairly prolonged
  • 15:06hospital course.
  • 15:09And the first couple of
  • 15:10days, she developed Pseudomonas, Bacteremia,
  • 15:12coli, UTI,
  • 15:13requiring IV antibiotics.
  • 15:16She was difficult to wean
  • 15:17off oppressors.
  • 15:20She was extubated day five.
  • 15:21And given the persistent
  • 15:23shock,
  • 15:25repeat coronary angiogram was again
  • 15:28performed and just redemonstrated
  • 15:30the occluded LAD
  • 15:32not amenable to PCI.
  • 15:36She started to have atrial
  • 15:37fibrillation with RVR, also had
  • 15:39a high PVC burden started
  • 15:40on amiodarone,
  • 15:42started to improve after
  • 15:44a week and had her
  • 15:46balloon pump removed on day
  • 15:47eight of her hospitalization.
  • 15:49Her pressers were weaned off,
  • 15:51and she was transitioned to
  • 15:52oral antibiotics on day ten.
  • 15:55Advanced therapies in the setting
  • 15:57of the her recovery and
  • 15:58infection was then deferred to
  • 16:00the outpatient setting.
  • 16:03Two weeks since she had
  • 16:04a repeated echo, showed that
  • 16:05her EF was relatively unchanged
  • 16:08with the kinesis of the
  • 16:09LED teratarpy,
  • 16:11and then showed this mural
  • 16:13thrombus measuring four point four
  • 16:15centimeters by one point one
  • 16:16centimeters.
  • 16:18On day eighteen, she was
  • 16:20discharged from the hospital on
  • 16:21aspirin, eliquis,
  • 16:23and amiodarone to a rehab
  • 16:24facility and to follow-up with
  • 16:26the v, VA cardiology team.
  • 16:29We were unable to start
  • 16:30GDMT due to hypotension.
  • 16:36Now in rehab, she was
  • 16:37then seen by doctor Charles
  • 16:39Phillips in the Newington VA
  • 16:40Cardiology Clinic.
  • 16:42Over the next several months,
  • 16:43she had symptoms of mild
  • 16:44dyspnea class you know, NYHA
  • 16:47class two
  • 16:49classification.
  • 16:52She was requiring Midadrine for
  • 16:53hypotension, which made which along
  • 16:55with her kidney function made
  • 16:56GDMT difficult to titrate.
  • 17:01She had a series of
  • 17:02echocardiograms
  • 17:03then during this period.
  • 17:06The first one, which was
  • 17:08two months
  • 17:09after she was discharged,
  • 17:11showed,
  • 17:13an unchanged ejection fraction around
  • 17:15thirty five percent, but there
  • 17:16were signs of apical remodeling
  • 17:18as the entire apex was
  • 17:19not aneurysmal.
  • 17:21However, there was no signs
  • 17:23of LV thrombus.
  • 17:25And what I have shown
  • 17:26here is the noncontrasted
  • 17:27images,
  • 17:29and the different apical views
  • 17:31and then under it, the
  • 17:32corresponding contrast images.
  • 17:34Now get
  • 17:36despite,
  • 17:37given the evidence of the
  • 17:38continued remodeling, shared decision making
  • 17:40with the patient,
  • 17:43Her it was decided to
  • 17:44continue her anticoagulation.
  • 17:47She then had another echocardiogram.
  • 17:50This is now seven months
  • 17:51post her hospitalization for consideration
  • 17:53of a primary prevention ICD.
  • 17:56Her EF was unchanged, but
  • 17:58the apical aneurysm of prearrant
  • 17:59increased in size. Now measuring
  • 18:00three point eight by three
  • 18:02point one centimeters
  • 18:03on her, compared to five
  • 18:05months prior.
  • 18:07There still continued to be
  • 18:09no signs of contrast, but
  • 18:10of note, contrast wasn't used
  • 18:11in this particular,
  • 18:13study.
  • 18:17Given these findings, I just
  • 18:18wanna take a moment to
  • 18:19sort of review,
  • 18:21LV aneurysms.
  • 18:23They most commonly occur after
  • 18:25a transmural,
  • 18:27my acute myocardial infarction,
  • 18:30due to LV remodeling. In
  • 18:31this process,
  • 18:32the infarction
  • 18:34leads
  • 18:36to fibrosis of the necrotic
  • 18:38tissue.
  • 18:39The infarcted myocardial myocardial undergoes
  • 18:42thinning
  • 18:43and loses contractility.
  • 18:45The wall stress against this
  • 18:47this thin wall
  • 18:48undergoes dilation reading through this
  • 18:50classical aneurysm bulging.
  • 18:54Depending on the degree of
  • 18:55aneurysm formation,
  • 18:57several complications can arise.
  • 19:00It can decrease the
  • 19:03LV ejection fraction and lead
  • 19:04to heart failure symptoms.
  • 19:07Due to blood pooling and
  • 19:08stasis in the aneurysmal segment,
  • 19:10thrombus can form.
  • 19:13The
  • 19:14dilation and lack of contractility
  • 19:16to the scarred segment
  • 19:18can lead to myocardial,
  • 19:20to mitral valve dysfunction.
  • 19:22And then certainly because of
  • 19:24the heavy scar burn, this
  • 19:26this region can be a
  • 19:27substrate for ventricular arrhythmias.
  • 19:30Fortunately, the incidence of LV
  • 19:32aneurysm has greatly decreased,
  • 19:34over
  • 19:35the over the past few
  • 19:36decades. In thrombolytic era, incidence
  • 19:38was measured for as low
  • 19:39seventeen up to nineteen percent.
  • 19:42And now in the current
  • 19:43PCI era,
  • 19:45is about is less than
  • 19:46five percent.
  • 19:50Management is
  • 19:51of these aneurysms is dictated
  • 19:54by complications.
  • 19:56So here's sort of a
  • 19:58chart that I adapted.
  • 20:01If you have heart failure
  • 20:03symptoms and LV dysfunction,
  • 20:05you're gonna elect for guide
  • 20:07you know, guideline directed medical
  • 20:09therapy. Certainly, if there's
  • 20:11revascularization
  • 20:13or ischemic territory that can
  • 20:14be revascularized, you would consider
  • 20:16PCI or CABG.
  • 20:20If there's mitral regurgitation, you
  • 20:21can try medical management, reduce
  • 20:23the afterload with ACE inhibitors
  • 20:26or ARBs.
  • 20:28If
  • 20:29there's if there's evidence of
  • 20:30thromboembolism,
  • 20:32vitamin k antagonists or DOACs,
  • 20:35can be used. And if
  • 20:36certainly, if there's ventricular arrhythmias,
  • 20:38aneurythmic drug therapy or ablation
  • 20:40should be considered and in
  • 20:41appropriate patients that meet indications,
  • 20:44an ICD placed.
  • 20:46Now if these sort these
  • 20:48measures fail,
  • 20:50that's when we have to
  • 20:51start considering surgical repair of
  • 20:53the aneurysm.
  • 20:55And what do our guidelines
  • 20:56say about surgical managements?
  • 21:00These are the really the
  • 21:02two most recent guidelines, the
  • 21:03STEMI guidelines that comment on
  • 21:05it. On the left is
  • 21:06the two thousand four STEMI
  • 21:07guidelines,
  • 21:08which gives a, class two
  • 21:09a recommendation
  • 21:11for
  • 21:12surgical aneuryscectomy
  • 21:14if there's intractable ventricular tachyarrhythmias
  • 21:17or pump failure refractory to
  • 21:20medical or catheter based therapies.
  • 21:22The more recent two thousand
  • 21:23thirteen STEMI guidelines, they don't
  • 21:25give a formal recommendation,
  • 21:27but the they make a
  • 21:28statement to consider repair for
  • 21:30treatment of heart failure,
  • 21:31ventricular arrhythmia is not a
  • 21:33minimal to drugs or ablation,
  • 21:35or recurrent thromboembolism
  • 21:37despite appropriate,
  • 21:39anticoagulation
  • 21:40therapy.
  • 21:45Now given all this in
  • 21:46mind, let's go back to
  • 21:47our case.
  • 21:50Now for about
  • 21:52the next,
  • 21:53year and a half, the
  • 21:54patient was, was continued to
  • 21:56be seen in clinic.
  • 21:58Her symptoms
  • 21:59were really unchanged.
  • 22:01Still mild dyspnea, NYHA class
  • 22:03two.
  • 22:05She received a primary prevention
  • 22:06ICD for unrecovered ejection fraction,
  • 22:10And we were also able
  • 22:11to get her started on
  • 22:12minimal g d n t
  • 22:13therapy due to improvement in
  • 22:15her blood pressure.
  • 22:16And then given really lack
  • 22:17of symptoms and lack of
  • 22:19these complications that, I mentioned
  • 22:21serial imaging
  • 22:23of the of, the aneurysm
  • 22:25was discontinued.
  • 22:28She had a repeat echo
  • 22:30in October twenty twenty four.
  • 22:31Now we're about a year
  • 22:32and a half after her
  • 22:33hospitalization.
  • 22:36Unfortunately, the aneurysm continued to
  • 22:37grow in size. It was
  • 22:38now measured to be three
  • 22:39point nine over four point
  • 22:41six centimeters
  • 22:42with contrast.
  • 22:45And now
  • 22:46despite being on anticoagulation,
  • 22:48it was discovered that she
  • 22:50had a large mural thrombus.
  • 22:53So this is just so
  • 22:54you can have an appreciation
  • 22:55for,
  • 22:58the aneurysm. And now I'm
  • 22:59gonna show you the parasternal
  • 23:00long view with contrast.
  • 23:03And you can see sort
  • 23:04of this,
  • 23:06this aneurysm,
  • 23:08black
  • 23:10and the contrasted images.
  • 23:12And then lastly,
  • 23:13it was discovered she has
  • 23:14a VSD.
  • 23:15A ventricular septal defect,
  • 23:18was also present.
  • 23:21Fortunately, at least the, there
  • 23:22wasn't any significant,
  • 23:24change to her mitral regurgitation.
  • 23:28And
  • 23:30now I'm gonna just take
  • 23:31a minute just to talk
  • 23:32about the echo imigings of
  • 23:33LV aneurysm and thrombus.
  • 23:35Echo is the first line
  • 23:36imaging modality
  • 23:39for LV thrombus. It,
  • 23:42can help distinguish
  • 23:45sorry. First line imaging modality
  • 23:46for LV aneurysms and thrombus.
  • 23:50It can distinguish between true
  • 23:52versus pseudoaneurysms.
  • 23:54And one of the one
  • 23:55of the key ways it
  • 23:55can do that is by
  • 23:56looking at the internal neck
  • 23:58diameter versus the sac diameter
  • 24:00ratio.
  • 24:01Typically,
  • 24:03when the ratio is point
  • 24:05five to one,
  • 24:07meaning a sort of a
  • 24:09larger
  • 24:10neck, then this corresponds
  • 24:12to a,
  • 24:14true aneurysm
  • 24:15versus a pseudo aneurysm or
  • 24:16false aneurysm where this ratio
  • 24:17is less than point five.
  • 24:19Certainly and when I say
  • 24:20pseudo aneurysm, it means sort
  • 24:22of complete rupture of the
  • 24:23wall
  • 24:24of of the LV wall
  • 24:27and,
  • 24:29blood contents going into filling
  • 24:30the pericardial space.
  • 24:33Now in terms of thrombus
  • 24:34identification with echo,
  • 24:37where it's not as strong
  • 24:39as other imaging mortalities
  • 24:40is its sensitivity and a
  • 24:42definite thrombus. With no contrast,
  • 24:44the sensitivity is thirty seven
  • 24:45percent.
  • 24:46With contrast, that increases to
  • 24:48sixty four percent.
  • 24:50And then the specificity
  • 24:52of
  • 24:53but the specificity
  • 24:54is comparable to that of
  • 24:56cardiac MRI
  • 24:57where with contrast to ease
  • 24:59of a ninety nine percent
  • 25:07The difficulties of doing imaging
  • 25:09of LV aneurysms and thrombus
  • 25:10with echo,
  • 25:13first, it's difficult to compare
  • 25:15the aneurysm size
  • 25:17and thrombus
  • 25:18on echo.
  • 25:21Echo can underestimate the aneurysm
  • 25:24size mostly due to foreshortening,
  • 25:26which can miss the true
  • 25:27LV apex or the thrombus.
  • 25:31It should be, you know,
  • 25:33it should be considered to
  • 25:35per because of the increased
  • 25:36sensitivity, the study should be
  • 25:37performed with contrast.
  • 25:39And then volumetric imaging of
  • 25:41the aneurysm
  • 25:42could can also be helpful
  • 25:43in these cases.
  • 25:46Now
  • 25:50so what I have here
  • 25:52and just to so you
  • 25:53can appreciate that point is
  • 25:55that we have these echo
  • 25:56images.
  • 25:57And the first ones are
  • 25:58images in twenty twenty three
  • 25:59and then in twenty twenty
  • 26:00five
  • 26:02in the same apical views.
  • 26:04And what you can hopefully
  • 26:06appreciate
  • 26:06is that it's it's really
  • 26:08difficult to tell,
  • 26:10changes
  • 26:12between the sizes, you know,
  • 26:13over this two year period.
  • 26:16You know, if you're just
  • 26:17looking qualitatively, sometimes it can
  • 26:19look unchanged.
  • 26:26Now aside from her cardiac
  • 26:28care, the patient was also
  • 26:29getting worked up for pulmonary
  • 26:31nodules,
  • 26:32and she received a low
  • 26:33dose CT scan
  • 26:34that showed that the aneurysm
  • 26:36size has almost doubled in
  • 26:38dimensions compared to our prior
  • 26:39echo, which raised a lot
  • 26:40of concern.
  • 26:41So I'm gonna ask, doctor
  • 26:43Philip Mora,
  • 26:45to discuss these,
  • 26:47these findings in detail. And,
  • 26:49also, he's gonna give us
  • 26:50his expertise on the role
  • 26:51of CT and imaging for
  • 26:53these cases.
  • 27:01So we generally don't read
  • 27:03low dose CTs,
  • 27:05but,
  • 27:06you know, it's a not
  • 27:07that it's not it's not
  • 27:08a cardiac dedicated study, so
  • 27:10there's no contrast.
  • 27:12So it's hard to take
  • 27:13a lot away from it.
  • 27:14But
  • 27:15surprisingly enough, if you if
  • 27:16you if you put effort,
  • 27:18you can get a lot
  • 27:19of information. And I think
  • 27:20we were able to get
  • 27:21a nice piece of information
  • 27:23here. You know, you see
  • 27:24here, we have reconstructed for
  • 27:26you in the sagittal, the
  • 27:28coronal, and the axial views.
  • 27:30You see this bulging,
  • 27:33apex,
  • 27:34that
  • 27:36expands outside of the regular
  • 27:37contours
  • 27:39of the myocardium, you know,
  • 27:40extending even
  • 27:42below the the diaphragm,
  • 27:43and nicely enough. You can
  • 27:45use the ICD as, as
  • 27:47a reference,
  • 27:49for where that might be,
  • 27:51even though we essentially have
  • 27:52no contrast at images.
  • 27:54And then,
  • 27:55if you click,
  • 27:57can you go forward one?
  • 28:00So this is the twenty
  • 28:02twenty five one that we
  • 28:03just looked at. But if
  • 28:04you compare it with the
  • 28:05same,
  • 28:07acquisition that was done
  • 28:09a year prior,
  • 28:11you can appreciate at least
  • 28:13visually,
  • 28:14you know, the extension of
  • 28:16the bulging,
  • 28:17apex, you know, below the
  • 28:19the ICD and the diaphragm
  • 28:21seemed less substantial.
  • 28:23Now,
  • 28:23the the,
  • 28:25the left lateral,
  • 28:26left to right dimensions appear
  • 28:28about the same size. But
  • 28:30if you look at
  • 28:31the cranial to caudal dimensions
  • 28:33and the anterior to posterior,
  • 28:35dimensions,
  • 28:36they look a bit enlarged.
  • 28:38And we're actually able to,
  • 28:40do a little bit of,
  • 28:42use a tool where we
  • 28:43kind of try to get
  • 28:44a,
  • 28:45a really a really poor
  • 28:46man's assessment of volume.
  • 28:49But interestingly enough,
  • 28:51if you actually if you
  • 28:52look at the aneurysm
  • 28:54on the right, the one
  • 28:55from a year prior, where
  • 28:57we got an estimation of
  • 28:58about thirty six,
  • 29:00forty five cc's,
  • 29:02if you compare that to
  • 29:03the echo done about the
  • 29:05same time
  • 29:06where that bulge had a
  • 29:08spherical radius
  • 29:09of about two point one,
  • 29:11two point two,
  • 29:15centimeters,
  • 29:16it actually pairs up, relatively
  • 29:18well in terms of volume.
  • 29:20If you use that,
  • 29:22mathematically, you get about thirty
  • 29:23eight, ml.
  • 29:25So that was kinda interesting
  • 29:27to to note. But, you
  • 29:28know, it's not a dedicated
  • 29:29study, but it it raised
  • 29:30definitely raised concern that there
  • 29:32might be,
  • 29:33there might have there there
  • 29:34had been some, interval increase
  • 29:36in size over the course
  • 29:38of a year.
  • 29:40And then, you know, generally
  • 29:41speaking,
  • 29:43you know, for assessment of
  • 29:44aneurysm of the LV and
  • 29:47or thrombus,
  • 29:48your your go to is
  • 29:49a cardiac MRI.
  • 29:51You have higher, spatial resolution,
  • 29:54as well as tissue,
  • 29:56differentiation with what you can
  • 29:57do in in cardiac MRI.
  • 29:59But it is
  • 30:00reasonable to to pursue a
  • 30:02CT, particularly if you can't,
  • 30:04can't conduct a cardiac MRI
  • 30:06in a patient.
  • 30:07And that we find in
  • 30:08the guidelines,
  • 30:09both in US and Europe.
  • 30:12And, you know, not only
  • 30:13can we do a volumetric
  • 30:14analysis,
  • 30:15but with the, with CT,
  • 30:17we can also do delayed
  • 30:18enhancement imaging as well.
  • 30:20So, you know, not just
  • 30:22the arterial phase but if
  • 30:23you image in, you know,
  • 30:24between five or ten minutes,
  • 30:25depending on your protocol in
  • 30:27your lab,
  • 30:28you're able to see enhancement,
  • 30:31a delayed enhancement,
  • 30:32in where there is actually
  • 30:34still
  • 30:35myocardium, where would be the
  • 30:36case of a of an
  • 30:37aneurysm.
  • 30:38And if there if it
  • 30:39is, in fact, a pseudoaneurysm,
  • 30:41generally,
  • 30:42it's a much lower density,
  • 30:45structure,
  • 30:45and so that can be
  • 30:46used to differentiate one of
  • 30:48the two.
  • 30:51Thank you, doctor Moore. I'll
  • 30:52just keep it. I'll just
  • 30:53keep it there. And,
  • 30:58now
  • 30:59back to back to the
  • 31:00case, we have this,
  • 31:02given this rapid enlargement.
  • 31:05She was then admitted to
  • 31:06the VA,
  • 31:07for CT surgery evaluation.
  • 31:10But despite these imaging changes,
  • 31:14she still did not have
  • 31:15any progression of symptoms.
  • 31:19She was, switched
  • 31:20in the setting of this,
  • 31:26she had evidence of,
  • 31:28given the evidence of thrombus,
  • 31:30she was switched
  • 31:31from apixaban to Coumadin for,
  • 31:33DOAC failure. And now we
  • 31:35obtained a cardiac MRI to
  • 31:37really care to fully characterize
  • 31:38this aneurysm to help us
  • 31:39move forward in how to
  • 31:40manage it. And I'm gonna
  • 31:41ask doctor,
  • 31:43Emmanuel Quintoy to comment on
  • 31:44the MRI findings.
  • 31:46Alright. So,
  • 31:49so I would say,
  • 31:50the indication for cardiac MRI
  • 31:52in this kind of patient
  • 31:53would
  • 31:54definitely be to differentiate
  • 31:57between,
  • 31:58a true aneurysm
  • 31:59and a pseudo aneurysm, which
  • 32:01is a critical,
  • 32:04this,
  • 32:05determination to make because the
  • 32:07pseudo aneurysm, it's,
  • 32:09urgent. It require, like, urgent
  • 32:11repair because it could become,
  • 32:13like, a catastrophe
  • 32:15due to the high risk
  • 32:16of rupture.
  • 32:17So,
  • 32:18like, Ali already mentioned,
  • 32:21echo is the,
  • 32:22imaging mod first imaging modality,
  • 32:25but,
  • 32:27the
  • 32:27specificity of echo is limited.
  • 32:30And that's where where Kedac
  • 32:32MRI comes in to make
  • 32:33that important,
  • 32:35distinction.
  • 32:36So,
  • 32:37in terms of Kedac MRI,
  • 32:39we do a lot of,
  • 32:41sequence in order to,
  • 32:43make determination
  • 32:44of,
  • 32:45what's the exact,
  • 32:48pathology is.
  • 32:50And, we typically start with
  • 32:51the cine images. So as
  • 32:53you can see, this is
  • 32:54a
  • 32:57poor image quality, and this
  • 32:59it's poor image quality for
  • 33:00this particular case because this
  • 33:02patient already have an ICD.
  • 33:04Patient with ICD,
  • 33:06they it tends to limit
  • 33:08what kind of sequence,
  • 33:10we can do, and,
  • 33:12it affects,
  • 33:13the image quality. So the
  • 33:14image quality is degraded in
  • 33:16this particular picture. So this
  • 33:18is typically not what we
  • 33:19get for most of our
  • 33:20cardiac MRI.
  • 33:22But what is showing here
  • 33:23in this, senior images is
  • 33:25just the, long axis view.
  • 33:28And,
  • 33:28we can see the sac
  • 33:30coming from the inferior, epicoinfluorateral
  • 33:33wall.
  • 33:34Just looking at this in
  • 33:35the images, it's hard to
  • 33:36tell. Is this pseudo aneurysm?
  • 33:38Is this aneurysm?
  • 33:39So,
  • 33:41we rely on,
  • 33:42dedicated,
  • 33:44MRI sequence,
  • 33:45called the, delayed enhancement imaging,
  • 33:48which is what is shown
  • 33:50in this,
  • 33:50slide.
  • 33:53Like echo, we look at
  • 33:55we look at similar,
  • 33:56features just like echo.
  • 33:59Like Ali already mentioned, we
  • 34:00look at, the neck,
  • 34:03of the,
  • 34:04sac.
  • 34:05So less than fifty percent
  • 34:06means it's narrow.
  • 34:09So that suggests you do
  • 34:10aneurysm. If it's more than
  • 34:11that, that suggests aneurysm.
  • 34:14Also, we look at,
  • 34:17the location.
  • 34:18So,
  • 34:20a sac in the anterior
  • 34:21or,
  • 34:22apex,
  • 34:23most likely aneurysm. If it's
  • 34:25inferior, then it's most likely,
  • 34:28pseudo aneurysm.
  • 34:30And then we also look
  • 34:31at,
  • 34:32abrupt cutoff.
  • 34:34So between,
  • 34:37we look at the boundary
  • 34:38between the LV
  • 34:39and the sac. So is
  • 34:41there, like, an abrupt cutoff
  • 34:42between
  • 34:43the myocardium
  • 34:44and the sac? So if
  • 34:45there's an abrupt cutoff, then
  • 34:47it suggests that there's probably
  • 34:49a rupture there.
  • 34:50Right?
  • 34:52If there's no rupture, it
  • 34:53kind of tapers into the
  • 34:55sac.
  • 34:56If you look if you
  • 34:57use that, you probably say
  • 34:58this is probably a pseudo
  • 34:59aneurysm because it suggests that
  • 35:01there's an abrupt cutoff between
  • 35:03if you look at the,
  • 35:05infra lateral wall and the
  • 35:06beginning of the sacs, it
  • 35:08looks like I didn't couldn't
  • 35:09really appreciate any tapering there.
  • 35:12So and that tells you,
  • 35:14the limitation. It tells the
  • 35:16limitation of all these,
  • 35:18features.
  • 35:19Right? So where MRI actually
  • 35:21stands out is in the
  • 35:23tissue characterization.
  • 35:25So we can actually look
  • 35:26at the tissue and can
  • 35:27tell exactly what we,
  • 35:29dealing with.
  • 35:30And that is what is
  • 35:31shown in the zoom out,
  • 35:33image,
  • 35:33on the right.
  • 35:35So,
  • 35:36if you wanna put your
  • 35:38cursor there. So the the
  • 35:40dark part no. The dark
  • 35:42part yeah. So that's a
  • 35:43thrombus.
  • 35:44So we use a dedicated,
  • 35:47MRI image with,
  • 35:50called a long TI image
  • 35:51to look at, thrombus with
  • 35:53actually have very high sensitivity
  • 35:55and specificity.
  • 35:56So that tells you that's
  • 35:57a thrombus.
  • 35:58And then next after that,
  • 36:00you see the white line.
  • 36:02So that white line actually
  • 36:03is the infected myocardium.
  • 36:07So that tells you there
  • 36:08is, like, a a dead
  • 36:09myocardial tissue there. And then
  • 36:11after that is that
  • 36:13dark line. So that's the
  • 36:14pericardium.
  • 36:15So this is actually the
  • 36:17most specific way
  • 36:19to diagnose to differentiate it
  • 36:21from,
  • 36:22pseudo aneurysm.
  • 36:23If it was a pseudo
  • 36:24aneurysm, we're not gonna have
  • 36:26that
  • 36:27white line. So because there's
  • 36:29no there's no myocardial tissue
  • 36:30there. So all we're gonna
  • 36:32have is just a pericardial
  • 36:33tissue,
  • 36:34which most time is going
  • 36:36to be,
  • 36:37enhanced
  • 36:38because it's inflamed.
  • 36:39So this actually, I think
  • 36:41it's,
  • 36:42puts the question to bed
  • 36:44in in terms of whether
  • 36:45this is, aneurysm or pseudo
  • 36:47aneurysm.
  • 36:49Next slide.
  • 36:51So,
  • 36:52I guess this also was
  • 36:54acquired just to,
  • 36:57look at the,
  • 36:59thrombus burden.
  • 37:00It's still the,
  • 37:02delayed enhancement imaging.
  • 37:04And what it's showing here
  • 37:05is just short axis stacks
  • 37:07from,
  • 37:08like, the base to the
  • 37:09apex of the heart. And
  • 37:11as you can see from
  • 37:13the from the base of
  • 37:14the ape once we start
  • 37:15getting to the mid portion,
  • 37:16we start seeing thrombosis in
  • 37:18the
  • 37:19anterior septal wall,
  • 37:21number two.
  • 37:23Like, you can see thrombosis
  • 37:24lying there. And as you
  • 37:25move down from two, three
  • 37:29down to seven, then you
  • 37:30can start seeing additional thrombores
  • 37:32more
  • 37:33towards the,
  • 37:34latter the epicolateral wall. So
  • 37:36it just give you, like,
  • 37:38an assessment of,
  • 37:39the thrombores burden. So I
  • 37:41think this is just an
  • 37:42additional
  • 37:45information that,
  • 37:46MRI can give in this,
  • 37:48patient.
  • 37:50And I think you have
  • 37:51a slide. Okay. So this
  • 37:52is just,
  • 37:54teaching points that, Alias highlighted
  • 37:56as far as,
  • 37:58role of cardiac MRI,
  • 37:59in this kind of patient.
  • 38:01So as, shown in previous
  • 38:03slide, it provides the best
  • 38:04issue characterization.
  • 38:05It's the most,
  • 38:07specific
  • 38:08imaging modality to differentiate between,
  • 38:11true aneurysm and pseudo aneurysm.
  • 38:14It's the gold standard for
  • 38:15thrombus imaging.
  • 38:17So the sensitivity,
  • 38:18I believe, is from the
  • 38:20traditional delayed enhancement imaging with,
  • 38:23new,
  • 38:24modality new new sequences, the
  • 38:27long TI, I think the
  • 38:28sensitivity
  • 38:29for
  • 38:29of MRIs
  • 38:31in the high 90s.
  • 38:32So like ninety studies are
  • 38:34up to like ninety eight,
  • 38:35ninety eight, ninety nine percent.
  • 38:37And the specificity is in
  • 38:38the high 90s.
  • 38:40So gold standard for thrombus
  • 38:41imaging, gold standard for volumetric
  • 38:43analysis,
  • 38:44and it can also provide,
  • 38:46three d anatomical details similar
  • 38:48to CT. We typically don't
  • 38:49acquire a three d dataset,
  • 38:51but it's something that we
  • 38:52can do if, needed on
  • 38:53MRI.
  • 38:54Thanks.
  • 38:57Thanks, doctor Kintoy.
  • 39:01Now we'll go back to
  • 39:03our case. With all these
  • 39:04imaging findings, we then discussed
  • 39:06this,
  • 39:07the patient was then discussed
  • 39:09in our weekly,
  • 39:11VA heart meeting, which is
  • 39:13really one of the highlights
  • 39:14of being a cardiology fellow
  • 39:15here.
  • 39:16It's an interdisciplinary
  • 39:17conference with cardiology
  • 39:19and CT surgery attendings and
  • 39:20fellows spending really all aspects
  • 39:22of cardiovascular
  • 39:23care.
  • 39:25Given that there this aneurysm
  • 39:28has continued to enlarge
  • 39:29and that there was increasing
  • 39:31clot burden despite being on
  • 39:33anticoagulation,
  • 39:34surgical repair
  • 39:35was recommended.
  • 39:39The patient came to YNH
  • 39:41for
  • 39:42left ventricular restoration surgery by
  • 39:44doctor Roland Ossie. Fortunately, doctor
  • 39:46Ossie has a case today.
  • 39:48He was unable to join
  • 39:49us
  • 39:50to go over the nuances
  • 39:52of the surgery, and I
  • 39:52will do my best to
  • 39:53do justice to what really
  • 39:55was an incredible surgery. That's
  • 39:57for all your security.
  • 40:05Now the goals of the
  • 40:07surgery are outlined here. This
  • 40:08as you can,
  • 40:11the principle of addressing a
  • 40:12large
  • 40:13LV aneurysm are as follows.
  • 40:15First, enter the infarcted nonviable
  • 40:18tissue.
  • 40:18This way, we're not damaging
  • 40:20the viable tissue.
  • 40:22And the capsule
  • 40:24of the aneurysm is actually
  • 40:25quite
  • 40:26while it's thin, it's quite,
  • 40:28it's relatively tough material.
  • 40:31This area, as you can
  • 40:32see, it will become when
  • 40:34this patient,
  • 40:35goes under bypass,
  • 40:37it will become compressed. And
  • 40:38this all this compressed collapsed
  • 40:40tissue is all aneurysm, measuring
  • 40:42about fifteen centimeters.
  • 40:47The
  • 40:50now as you can see
  • 40:51in the fall, while,
  • 40:52you know, we're gonna
  • 40:54we're gonna while we reconstruct
  • 40:56this, we're gonna also actually
  • 40:57keep this collapsed tissue because
  • 40:59it can serve as extra
  • 41:00tissue for the the surgery.
  • 41:02And, typically, the approach is
  • 41:04to enter through the middle
  • 41:04of the scar.
  • 41:07Here, you see the team
  • 41:08entering the infarcted tissue.
  • 41:11You get a sense of
  • 41:12how tough this tissue can
  • 41:14become, but also how thin
  • 41:15it is,
  • 41:17relative to normal LV muscle
  • 41:19the the normal LV.
  • 41:21In the case upon
  • 41:22when they entered the LV
  • 41:24cavity,
  • 41:25there was a large amount
  • 41:26of old clot,
  • 41:28which is you which is
  • 41:30this, like, yellow and fiberness
  • 41:32material,
  • 41:33which is consistent with long
  • 41:34standing clot as opposed to
  • 41:36fresh clot, which would be
  • 41:37more red and less well
  • 41:38organized.
  • 41:42And now after
  • 41:44removing the tissue, rather than
  • 41:45removing the aneurysmal tissue, its
  • 41:47capsular can be used as
  • 41:48the end as I mentioned,
  • 41:49at the end of the
  • 41:50case to reinforce closure
  • 41:52of the incision in the
  • 41:53LV.
  • 41:56The photo on the left
  • 41:57shows the aneurysm, which has
  • 41:59been opened up,
  • 42:00and multiple black sutures are
  • 42:02there to retract the wall
  • 42:03of the the walls of
  • 42:05the aneurysm and keep it
  • 42:06open, providing
  • 42:08exposure to the surgeons.
  • 42:09The white tissue, as you
  • 42:11see, that's all scar.
  • 42:15The suction is is is
  • 42:17inside the true LV cavity,
  • 42:20and you can see the
  • 42:20mitral valve and the trabeculations
  • 42:23of the LV. And one
  • 42:24thing to notice is that
  • 42:25these trabeculations are gone,
  • 42:28in the aneurysms
  • 42:29in the aneurysmal segment.
  • 42:33Also, to highlight the picture
  • 42:34on the right, you can
  • 42:35shows the small ventricular septal
  • 42:37defect that will also need
  • 42:39to be closed when the
  • 42:40aneurysm is patched.
  • 42:46Now one of the most
  • 42:47important parts of the operation
  • 42:49is to recreate
  • 42:50this new LV cavity with
  • 42:52the appropriate geometry.
  • 42:55And to do this, though,
  • 42:57we're gonna be placing a
  • 42:58they're gonna place a patch
  • 43:00at the mouth of the
  • 43:01aneurysm sac. In this case,
  • 43:03it's a big area, and
  • 43:04there's different ways,
  • 43:06after talking with doctor Austin
  • 43:07and doctor Pelletier that there
  • 43:08are to do this.
  • 43:10In this case, a bovine
  • 43:11pericardium was used along with
  • 43:15felt,
  • 43:16felt, pledge
  • 43:19it to reinforce the closure.
  • 43:23And sutures are placed in
  • 43:24a circumferential
  • 43:25manner
  • 43:26around the neck of the
  • 43:27aneurysm and then pass through
  • 43:29the patch.
  • 43:31The most important thing is
  • 43:33to ensure the LV cavity
  • 43:35is not too small.
  • 43:37In
  • 43:38some cases, they,
  • 43:40they would actually
  • 43:41fill a balloon with saline
  • 43:43that's in that's
  • 43:45that's to the right size
  • 43:46based on body surface area
  • 43:48and,
  • 43:51use that to sort of
  • 43:52give you the right geometry
  • 43:53of the LV and the
  • 43:54size. In this case, the
  • 43:56aneurysm was so large and
  • 43:58it wasn't needed.
  • 44:00The picture on the right
  • 44:01shows the
  • 44:03the patch repair,
  • 44:04and now the repair is
  • 44:06gonna be reinforced
  • 44:07with the aneurysmal tissue on
  • 44:09top of it.
  • 44:12That that's why it doesn't
  • 44:14just close the aneurysm because,
  • 44:16you know, you can imagine
  • 44:17if you do pick the
  • 44:18edges where the belt is
  • 44:19and and you close,
  • 44:21but they create a l
  • 44:22b cavity that's too small.
  • 44:24So that's why they use
  • 44:25this patch
  • 44:26to allow,
  • 44:27you know, not preload.
  • 44:30So for the vision, they
  • 44:30still don't have there.
  • 44:36So this is the completed
  • 44:38restoration,
  • 44:39and the results were excellent.
  • 44:41Here I have the
  • 44:44the presurgery and post op
  • 44:46TES.
  • 44:48As a little difficult to
  • 44:50appreciate, but the the LVEF
  • 44:52is tremendously improved, probably to
  • 44:53forty to forty five percent,
  • 44:55and there was no evidence
  • 44:56of thrombus.
  • 44:59In terms of the VSD
  • 45:00shunt, as you can see,
  • 45:01presurgery, there was a a
  • 45:02shunt that's no longer a
  • 45:03a shunt going from left
  • 45:05to right flow.
  • 45:08And then in terms of
  • 45:09the mitral valve
  • 45:11apparatus,
  • 45:11the patient continued to have
  • 45:13stable MR,
  • 45:15meaning that it was,
  • 45:16intact.
  • 45:18Were the corners reshot
  • 45:21the LIV
  • 45:22occlusion was left?
  • 45:25We reshot them when she
  • 45:26originally presented. They haven't
  • 45:29they were reshot in planning
  • 45:30for the procedure.
  • 45:33But,
  • 45:33good question.
  • 45:35Surgery.
  • 45:43The patient had an uncomplicated
  • 45:45post op course.
  • 45:46She came in. She was
  • 45:47transferred to CTICU on epinephrine
  • 45:50and norepinephrine.
  • 45:51But within four days, was
  • 45:52weaned off pressers and extubated.
  • 45:54She was transferred to the
  • 45:55floor on day post op
  • 45:56day four.
  • 45:57And then with the and
  • 45:59post op day seven, she
  • 46:00was discharged on apixaban
  • 46:02and aspirin.
  • 46:04And
  • 46:05overall, the patient's doing quite
  • 46:06well.
  • 46:07Doctor Phillips just saw recently,
  • 46:09she still has this mild
  • 46:10dyspnea that's unchanged.
  • 46:12And
  • 46:13we have this is her
  • 46:14echo,
  • 46:16TT, transthoracic echo, one month
  • 46:18post op,
  • 46:20showing
  • 46:21that her EF is still
  • 46:23maintaining a forty to forty
  • 46:24five percent,
  • 46:26without any signs of
  • 46:28no signs of LV thrombus
  • 46:32and then trace mitral regurgitation.
  • 46:36So with that, I would
  • 46:37like
  • 46:38to conclude.
  • 46:40LV aneurysms are a possible
  • 46:42complication of transmural myocardial infarctions.
  • 46:46Echocardiography
  • 46:47is the first line imaging
  • 46:49modality,
  • 46:50but less sensitive than CT
  • 46:52and MRI, especially for assessing
  • 46:54aneurysm size and thrombus burden.
  • 46:58CT and MRI provide the
  • 46:59most accurate assessment of of
  • 47:01aneurysm size and thrombus
  • 47:05burden.
  • 47:06As for this case, surgery
  • 47:07should be considered
  • 47:09if patients have a concomitant
  • 47:10cardiac surgery for significant valve
  • 47:12disease
  • 47:13or bypass
  • 47:15coronary bypass surgery.
  • 47:17Ventricular arrhythmia is unresponsive
  • 47:20to,
  • 47:21medical or ablation therapies, refractory
  • 47:24heart failure despite medical therapy,
  • 47:26and as for this case,
  • 47:27increasing thrombosis burden despite appropriate
  • 47:30anticoagulation.
  • 47:31And what I hope I've
  • 47:32demonstrated is that this case
  • 47:34highlights the importance of multidisciplinary
  • 47:36cardiac teams and the management
  • 47:38complex LV aneurysms.
  • 47:42I'd like to acknowledge all
  • 47:43it's
  • 47:44because because it took such
  • 47:45a large team for this
  • 47:46case, I'd like to acknowledge
  • 47:47really everyone that helped put
  • 47:48this case presentation together.
  • 47:51Doctor Charles Phillips,
  • 47:53who's the patient's primary cardiologist
  • 47:55and was, my mentor for
  • 47:57this presentation.
  • 47:59Appreciate doctor Sugang, doctor Mora,
  • 48:02and doctor
  • 48:03Akintoy's,
  • 48:05guidance on the imaging,
  • 48:07and then, doctor Roland Ossie,
  • 48:10doctor Palatir,
  • 48:11and doctor Williams for their
  • 48:13input on the surgery.
  • 48:15Certainly, we have an excellent
  • 48:17VA.
  • 48:20Our VA Connect health system
  • 48:21is excellent. It's one of
  • 48:22the highlights of being a
  • 48:23fellow here,
  • 48:25and it's really rich to
  • 48:26see the collaboration between
  • 48:29them and Yale New Haven
  • 48:30Hospital.
  • 48:31And I like to also
  • 48:32acknowledge the continued support of
  • 48:33the cardiology fellowship program over
  • 48:35the last three years.
  • 48:37And with that, we'll be
  • 48:38happy to take any questions.
  • 48:46Okay. Fantastic
  • 48:48job.
  • 48:49Thanks.
  • 48:50And probably Steve or others,
  • 48:51if I can identify what
  • 48:52my questions are gonna be
  • 48:54or kind of the focus.
  • 48:55So I'm very interested in
  • 48:56in kind of just,
  • 48:58first of all, excellent result,
  • 49:00great,
  • 49:01technical and and surgical,
  • 49:03decision making and collaboration. It's
  • 49:04fantastic.
  • 49:06But I'm I'm very curious
  • 49:07at the initial presentation,
  • 49:12whether coronary artery bypass graft,
  • 49:16surgery was considered and
  • 49:18whether, you know, there's some
  • 49:20suggestion that maybe there was
  • 49:21infarct expansion that could have
  • 49:22been preventable, and, obviously, VSD
  • 49:24occurred afterwards
  • 49:25that could have been preventable,
  • 49:27you know, leaving this patient,
  • 49:29you know,
  • 49:30under revascularized,
  • 49:31I guess. And I'm just
  • 49:32curious from Steve or anyone
  • 49:34or Charles Charles or anyone
  • 49:35who was there at the
  • 49:36time whether
  • 49:37that conversation happened and what
  • 49:39your thoughts about that, was
  • 49:41and
  • 49:41and whether viability imaging or
  • 49:43anything came into play.
  • 49:48So I'll I'll dodge it
  • 49:49a little bit and say
  • 49:50that I wasn't there. Because
  • 49:52so this patient presented the
  • 49:54Saint Mary's in Waterbury and
  • 49:55that was transferred to Yale,
  • 49:56and I don't know who
  • 49:57the operator was here
  • 49:59who tried to open it
  • 50:00or made the decision to
  • 50:01leave it closed.
  • 50:03But I think
  • 50:04that reading through the chart,
  • 50:05the consensus was that it
  • 50:07was a late presentation infarct
  • 50:09and whatever was done was
  • 50:10done, and it was already
  • 50:11infarcted. There was a large
  • 50:12thrombus burden in the apex
  • 50:13already. The apex was thinned
  • 50:15out. And I I think
  • 50:17they made the decision to
  • 50:18not push the issue in
  • 50:19terms of revascularization.
  • 50:21And as you saw from,
  • 50:23the stills that Ali presented,
  • 50:25but if you look at
  • 50:26the angiograms, you'd really never
  • 50:27visualize the distal LED.
  • 50:29And so I think that
  • 50:30was not a big part
  • 50:32of the consideration.
  • 50:34So, you know, I think
  • 50:36when she came to Saint
  • 50:37Mary's,
  • 50:39they were able to get
  • 50:40a wire across it. They
  • 50:40actually ballooned it, but there
  • 50:42was no flow ever restored.
  • 50:44And,
  • 50:45I don't remember I don't
  • 50:46think they did any intracoronary
  • 50:48imaging, which would have been
  • 50:49very interesting to see,
  • 50:52but they decided to leave
  • 50:53it be at that point.
  • 50:54And then when she came
  • 50:56to Yale,
  • 50:57the findings were unchanged.
  • 50:59So it's a good point,
  • 51:00except I think the the
  • 51:01the conclusion was that it
  • 51:02was just a late presentation
  • 51:04infarct, and it was all
  • 51:05out of the barn.
  • 51:11Two comments. One is the
  • 51:13the inability to,
  • 51:15expand
  • 51:16GDMT
  • 51:18in a way reflects the
  • 51:19fact that there is, you
  • 51:21know, obviously,
  • 51:22in a,
  • 51:24flow going it's like MR.
  • 51:25It's like flow is going
  • 51:25in the opposite direction. Right?
  • 51:27So you're using the the
  • 51:28the aneurysm is becoming a
  • 51:30receptacle
  • 51:31for, you know, no for
  • 51:33non forward flow,
  • 51:34and that's decreasing, you know,
  • 51:36obviously,
  • 51:37useful cardiac output and and
  • 51:39actually
  • 51:40and reducing the opportunity to
  • 51:42start things. So I think,
  • 51:44even though the patient didn't
  • 51:45have refractory heart failure, I
  • 51:47would argue that the inability
  • 51:48to to move,
  • 51:50GDMT forward,
  • 51:53you know,
  • 51:54with an early indication
  • 51:56that this patient would you
  • 51:57know, that this was affecting
  • 51:58their their, their output and
  • 52:00and, obviously, increasing wall stress
  • 52:02and all that from that.
  • 52:03The the third option, which
  • 52:04is maybe I'd love to
  • 52:06hear Matt talk about this
  • 52:07a bit around the different
  • 52:08the evolution of this technique
  • 52:10and how it's, you know,
  • 52:11it's really a tremendously interesting
  • 52:13story spanning fifty years, I
  • 52:14think, plus
  • 52:16and others. But but, you
  • 52:17know,
  • 52:18we're gonna have Dan Bercoff
  • 52:20here in a few weeks,
  • 52:21months. I can't remember, Catherine.
  • 52:24And THT and, is down
  • 52:26around the corner and CRF,
  • 52:28the the the,
  • 52:30that conference finished. But there's
  • 52:32a lot of interest to,
  • 52:34renewed interest in,
  • 52:36both surgical as well as
  • 52:37percutaneous devices,
  • 52:40that can be placed to
  • 52:41reduce expansion
  • 52:43of these of these aneurysms
  • 52:45in patients with true you
  • 52:46know, with severe aneurysms with
  • 52:47this, but also just people
  • 52:48with very large LVs post
  • 52:50infarct.
  • 52:53So it's just something that
  • 52:54to keep on the radar.
  • 52:55And, Dan, I'm sure we'll
  • 52:56talk about that when he
  • 52:56comes. If you wanna talk
  • 52:58about the surgical
  • 53:00Yeah. I'm I'm far from
  • 53:01an expert in this, but
  • 53:02I can remember watching on,
  • 53:04PBS,
  • 53:05doctor Batista in Brazil. They
  • 53:07they did a whole hour
  • 53:08long special with
  • 53:10how his,
  • 53:11aneurysm reduction surgery was,
  • 53:14working miracles for these patients
  • 53:16in Brazil.
  • 53:17He, he worked in an
  • 53:18ICU where there weren't a
  • 53:20lot of,
  • 53:21good ways to monitor patients.
  • 53:23And I remember he looked
  • 53:24at the camera and held
  • 53:25up
  • 53:26a held up a,
  • 53:28urinary catheter Foley receptacle and
  • 53:30said, this is my monitor.
  • 53:33So,
  • 53:34anyway,
  • 53:35it became a very hot,
  • 53:37popular
  • 53:38operation
  • 53:39when I was a general
  • 53:40surgery resident. Even as a
  • 53:41fellow, I can remember at
  • 53:43Duke. Eric, you were there
  • 53:44too. The the
  • 53:46there would be two or
  • 53:46three
  • 53:49door operations on the schedule
  • 53:51every month, and,
  • 53:52you know, we'd probably do
  • 53:54one or two a year
  • 53:54here now.
  • 53:56My recollection is that there
  • 53:58was a,
  • 53:59a big trial that did
  • 54:00not show any benefit for
  • 54:01the procedure, and it just
  • 54:03kinda
  • 54:04went away at that point.
  • 54:05So,
  • 54:07I think that the indications
  • 54:10remain murky.
  • 54:12This patient, it seemed like
  • 54:13you guys decided to tackle
  • 54:16this because of increasing clot
  • 54:17burden and
  • 54:19risk of stroke. I think
  • 54:20the indication for refractory heart
  • 54:22failure is,
  • 54:24you know, not as reliable,
  • 54:25whether you're actually gonna make
  • 54:27people better or not, whether
  • 54:28it's worth
  • 54:30the risk we impose by
  • 54:31doing this complex operation,
  • 54:34is unknown, and that's why
  • 54:35so few of them are
  • 54:36down.
  • 54:38So any other
  • 54:39comments on that issue?
  • 54:42Oh, I think it
  • 54:44send it around. Start this
  • 54:46way and go around.
  • 54:47Yeah. I think for us
  • 54:49in our multidisciplinary
  • 54:51conference, she was presented a
  • 54:53number of times and the
  • 54:54whole question was,
  • 54:55what are the indications? What
  • 54:56are the real indications? She
  • 54:58hadn't had a thromboembolic event,
  • 54:59it's impressive as the echoes
  • 55:01are. She hadn't had any
  • 55:03arrhythmias, she had an ICD,
  • 55:04which we could interrogate and
  • 55:06see she had no,
  • 55:08arrhythmias.
  • 55:08And,
  • 55:10you know, we actually were
  • 55:11able to advance her heart
  • 55:12failure therapy a little bit
  • 55:14over time.
  • 55:15So we had a pretty
  • 55:16vigorous debate about whether it
  • 55:17was worthwhile to proceed with
  • 55:19it, quite honestly.
  • 55:20And, Roland felt strongly that,
  • 55:23you know, the anatomy was
  • 55:24favorable and he could
  • 55:26improve things. And so I
  • 55:28think he was the big
  • 55:29force kind of moving forward
  • 55:31with surgery. And in retrospect,
  • 55:33it was the right choice.
  • 55:34She's done very well. So
  • 55:35but it was a hot
  • 55:36topic of debate, to say
  • 55:37the least.
  • 55:43Jeff?
  • 55:45Terrific
  • 55:46presentation.
  • 55:49So I have a couple
  • 55:50comments. One is a little
  • 55:52bit old school, which maybe
  • 55:54is a lot of my
  • 55:55comments these days, and and,
  • 55:57the other
  • 55:58maybe not so.
  • 56:00The the question
  • 56:01one is question. One is
  • 56:03not. The question is
  • 56:05the one term that I
  • 56:07never heard you mention in
  • 56:09the entire
  • 56:11presentation
  • 56:12was dyskinesis.
  • 56:13And so the reason I
  • 56:15said that's an old school
  • 56:17concept, and
  • 56:18those of you who have
  • 56:20been around for
  • 56:21a little while know that
  • 56:23we used to make a
  • 56:24big distinction between a segment
  • 56:26that was frankly disconnected
  • 56:28and one that was just
  • 56:30a large akinetic segment.
  • 56:32I I do believe
  • 56:34there's less of a deal
  • 56:36made out of that distinction
  • 56:37anymore, but but we used
  • 56:39to say that disconnect segments
  • 56:41were less likely to develop
  • 56:43big thrombi
  • 56:44because they are still moving
  • 56:46even if they're moving in
  • 56:47the wrong direction.
  • 56:48Whereas a large a kinetic
  • 56:50segment is just let's just
  • 56:51not moving when it's there.
  • 56:53And I was looking carefully.
  • 56:54Maybe Lisa can comment. I
  • 56:55was looking carefully at all
  • 56:57the echoes going through, and
  • 56:58it wasn't until the very
  • 57:00last two thousand five echo
  • 57:02that I that was sort
  • 57:04of a presurgical
  • 57:06echo that that I thought
  • 57:08I saw
  • 57:09frank dyskinesis.
  • 57:10So is that something that
  • 57:12we pay any attention to
  • 57:13anymore? Is it something that
  • 57:15we should still be using
  • 57:17as a distinction
  • 57:20for moving forward?
  • 57:25So,
  • 57:28when we call something that's
  • 57:29aneurysmal, that it already
  • 57:32includes the connotation that it
  • 57:33is disconnected.
  • 57:34It can be akinetic,
  • 57:36but, it's usually,
  • 57:38disconnected.
  • 57:40But we do use dyskinesis,
  • 57:43on its own,
  • 57:45even if there isn't an
  • 57:46aneurysm. So we we still
  • 57:47use those,
  • 57:50terminology of dyskinesis.
  • 57:53Not old school. Yeah.
  • 57:57The the non old school.
  • 57:58Comment.
  • 58:01A little bit about
  • 58:02the alpha biology of the
  • 58:04spark expansion.
  • 58:06And this is not a
  • 58:07question, but just kind of
  • 58:09a comment towards the future
  • 58:10a little bit is that,
  • 58:12you know, a lot of
  • 58:12people,
  • 58:14are really interested in what
  • 58:16actually causes this adverse remodeling.
  • 58:18And is there any are
  • 58:20there any early
  • 58:22molecular
  • 58:23intervention interventions
  • 58:24that could occur in order
  • 58:26to
  • 58:27forestall that or prevent it?
  • 58:29And, you know, I I
  • 58:30can't
  • 58:31make a comment without mentioning
  • 58:33the word inflammation. So there's
  • 58:34a lot of,
  • 58:36interesting inflammatory cells that
  • 58:39take residence in the area
  • 58:40of the infarct and the
  • 58:41peri infarct area that are
  • 58:43producing soluble factors
  • 58:45that probably promote this adverse
  • 58:47remodeling and how to
  • 58:49affect that and prevent that.
  • 58:51So that that's just a
  • 58:52comment sort of looking towards
  • 58:53the future,
  • 58:55because I think we still
  • 58:56don't know as much about
  • 58:58that as we as we
  • 58:59would like.
  • 59:09I mean, Emmanuel and
  • 59:11Please. I just wanna make
  • 59:12one comment. I'm Charles Phillip.
  • 59:14I was the her primary
  • 59:15provider since two thousand and
  • 59:16twenty three, and I wanna
  • 59:17commend Ali for doing a
  • 59:19great job summarizing her case
  • 59:21over the period of time.
  • 59:23You know, despite having two
  • 59:24mechanical complications from an MI,
  • 59:26both the BSD and the
  • 59:28aneurysm,
  • 59:29she
  • 59:32heart failure symptoms, angina symptoms,
  • 59:34and even arrhythmia.
  • 59:37So it's surprising that
  • 59:39despite these favorable,
  • 59:44favorable,
  • 59:45symptoms,
  • 59:46her aneurysm was getting bigger
  • 59:48on this the imaging modalities
  • 59:51as well as the cloud
  • 59:52burn despite being on low
  • 59:53dose g d m p
  • 59:54therapy and anticoagulation.
  • 59:56So, I'm
  • 59:57fortunate to work,
  • 59:58at the VA where we
  • 59:59had multiple discussions as doctor
  • 01:00:01Pfau alluded to, discussing her
  • 01:00:03case at length, reviewing her
  • 01:00:05cases, reviewing her imaging, and
  • 01:00:06rereviewing
  • 01:00:07new imaging,
  • 01:00:08discussing with in a multidisciplinary
  • 01:00:10approach with,
  • 01:00:12our,
  • 01:00:13imaging staff, our surgeons, our
  • 01:00:15intangential, and general cardiologists.
  • 01:00:17And,
  • 01:00:18we were able to collect
  • 01:00:19it. We make a decision
  • 01:00:20that hopefully will lead to
  • 01:00:21a good outcome in her
  • 01:00:22future.
  • 01:00:24I know the veteran is
  • 01:00:25very appreciative of the time
  • 01:00:26spent in her care, discussion
  • 01:00:27of her care,
  • 01:00:29and she keeps,
  • 01:00:32thanking all all the support
  • 01:00:33that was given both at
  • 01:00:34the VA and Yale in
  • 01:00:35terms of her overall outcome
  • 01:00:37and overall
  • 01:00:41care. Yeah.
  • 01:00:42So another question, actually. I
  • 01:00:43just wanted to make a
  • 01:00:44comment about,
  • 01:00:46the LV remodeling,
  • 01:00:47in this patient.
  • 01:00:49I believe one of the
  • 01:00:51reason
  • 01:00:52from talking to Ali, one
  • 01:00:53of the reason
  • 01:00:55why,
  • 01:00:57they also decide to do
  • 01:00:58surgery in this case was
  • 01:00:59because the,
  • 01:01:01aneurysm was rapidly progressing,
  • 01:01:03which is which is not
  • 01:01:05maybe probably the rate of
  • 01:01:07of,
  • 01:01:09of remodeling was probably exceed
  • 01:01:11what we expect for most
  • 01:01:12aneurysm.
  • 01:01:13We tend to see rapid
  • 01:01:14progression for pseudo aneurysm,
  • 01:01:16maybe less rapid for aneurysm.
  • 01:01:18But this case, it was
  • 01:01:19rapidly,
  • 01:01:21progressing.
  • 01:01:22I guess,
  • 01:01:23the theory I have in
  • 01:01:25this case was, the patient
  • 01:01:27also had a VSD.
  • 01:01:28So the VSD,
  • 01:01:30in this case,
  • 01:01:31VSD tends to cause,
  • 01:01:33volume overload on the left
  • 01:01:35side.
  • 01:01:36So I believe the volume
  • 01:01:38overload on the left side,
  • 01:01:39it's probably what is also
  • 01:01:41driving the rapid regression of,
  • 01:01:44the aneurysm size in this
  • 01:01:45patient.
  • 01:01:50Another thing.
  • 01:01:55Yeah.
  • 01:01:57Yeah. So maybe just a
  • 01:01:58couple comments, and then, again,
  • 01:02:00thank you. I mean, it's
  • 01:02:01just for for the trainees.
  • 01:02:03I mean, this is a
  • 01:02:04great case because you don't
  • 01:02:05see this very often. There's
  • 01:02:06many reasons why you don't
  • 01:02:06see this very often, but
  • 01:02:07I can tell you that,
  • 01:02:10when, you know,
  • 01:02:12when when I was training,
  • 01:02:13we saw much more of
  • 01:02:14this, and this was actually,
  • 01:02:17you know, a very hot
  • 01:02:19topic within the surgical and
  • 01:02:21cardiovascular
  • 01:02:22communities
  • 01:02:23around around how to optimize
  • 01:02:26approaches to these patients. I
  • 01:02:27think prevention,
  • 01:02:29as well as better
  • 01:02:32earlier presentation and evaluation
  • 01:02:35and and and restoration of
  • 01:02:37of coronary flow, I think,
  • 01:02:38has made a big difference
  • 01:02:39in in this.
  • 01:02:41You know, there
  • 01:02:44there is a distinction I
  • 01:02:45also would like to leave
  • 01:02:46people with,
  • 01:02:47between
  • 01:02:48kind of this aneurysmal
  • 01:02:51and
  • 01:02:52the kind of surgical ventricular
  • 01:02:55restoration or SVR or door
  • 01:02:57type procedures that were and
  • 01:02:59are still at some in
  • 01:03:00some places,
  • 01:03:01performed,
  • 01:03:02which are really looking to
  • 01:03:04kind of
  • 01:03:05reduce the ventricular
  • 01:03:07size to promote,
  • 01:03:10forward flow and improved outcomes
  • 01:03:11in heart failure patients, which
  • 01:03:13were tested in in, you
  • 01:03:15know, one of our one
  • 01:03:16of my trials many, many
  • 01:03:17years back. Publishers, like, in
  • 01:03:18two thousand nine. It's dated
  • 01:03:20now. But but, which didn't
  • 01:03:22show an advantage.
  • 01:03:23Hazard ratio was one of
  • 01:03:25of, of of that procedure
  • 01:03:27for kinda
  • 01:03:28akinetic
  • 01:03:29large ventricles.
  • 01:03:31But I think this is
  • 01:03:32a different situation, and these
  • 01:03:33patients were serve certainly not
  • 01:03:35randomized
  • 01:03:36in in our trials because
  • 01:03:37of of the size of
  • 01:03:38this ventricle.
  • 01:03:39But I think a very,
  • 01:03:40very interesting congratulations.
  • 01:03:42Wonderful job. And, congratulations to
  • 01:03:44Charles for keeping this patient,
  • 01:03:47doing so well and for
  • 01:03:48Roland and and and the
  • 01:03:49whole team for for their
  • 01:03:51care. So
  • 01:03:52Thanks, everyone.
