Interventional Echo

Question 1

What are the inclusion criteria (coaptation characteristics) for Mitraclip for functional MR?

Answer 1

coaptation length >/= 2mm

coaptation depth >/= 11mm

Question 2

What are the inclusion criteria (flail characteristics) for Mitraclip for flail MR?

Answer 2

flail gap < 10mm

flail width < 15mm

Question 3

Prior to the release of the Mitraclip, what must the echocardiographer demonstrate to ensure ideal positioning?

Answer 3

1. adequate capture of anterior and posterior leaflet
2. absence of high transmitral gradient (<6mmHg)
3. adequate mitral valve area (>2cm^2)
4. reduction in severity of MR

Question 4

Can LAA occlusion be performed in valvular afib?

Answer 4

No, there are no studies that have looked at this so it is contraindicated.

Question 5

Successful alcohol septal ablation is considered reduction in LVOT gradient of how much?

Answer 5

50%

Question 6

what were the exclusion criteria for the Mitraclip trials?

Answer 6

flail width > 15mm
flail gap > 10mm
coaptation depth > 11mm
coaptation length < 2mm
LVIDs > 55mm
MVA < 4.0
