- 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.
