ECHO- Interventional Echocardiography Flashcards
role of echo in RV myocardial biopsy
- improves localization of biopsy
Post Procedural echo assessment after TAVR
check for implantation depth and stent expansion
Complication after RV myocardial biopsy
TR
Cardiac Tamponade
Iatrogenic VSD
Challenges in post procedural assessment for potential AR post-TAVR
see pic
Multiparametric approach for echo assessment of aortic paravalvular regurgitation
in post-TAVR Paravalvular regurgitation,
see pic
Assessment of the location of PVL in TTE?
in post-TAVR Paravalvular regurgitation,
see pic
Where to determine the cthe PVL severity. where to identify the circumferential extent of regurgitation
in post-TAVR Paravalvular regurgitation,
- ventricular edge (stent skirt)
Assessment of PVL based on circumferential extent
in post-TAVR Paravalvular regurgitation,
Mild - <10%
Moderate - 10-29%
Severe- ≥30%
Assessment of post-TAVR paravalvular regurgitation using CWD jet density and PHT
severe is <200ms PHT
transcatheter mitral valve repair: edge to edge repair
- associated with what trial?
COAPT trial-
in post-TAVR Paravalvular regurgitation, will there be PW diastolic reversal in the descending aorta?
YES - Holodiastolic reversals with end diastolic velocity of >0.2m/sec
Anatomic suitability for edge-to-edge TMVR

evaluation of mitral valve using TEE
at midesophageal level, particularly with 60degree where you can see P1, P2 and P3
evaluation of mitral valve using TEE: Commissural view
60degree where you can see P1, P2 and P3
What is Flail Gap and Flail Width???
-in Transcatheter edge-to-edge MV repair

Assessment of MR after Percutaneous MV repair or replacement
same with native MR guidelines
Example of a Mitral valve rupture/perforation

Transcatheter mitral valve repair complications
common are partial clip detachment and pericardial tamponade
left atrial appendage occlusion. which views are important in TEE?
