What is shown in the following image?

AMVL perforation

What is Dehiscence?

breakdown of sutures leading to partial or complete detachment of the prosthesis from annulus.

Continuity Eq for EOA. What can be substituted for OT dimensions if needed.

sewing ring diameter

which goes where: Posterior Leaflet Prolapse and Anterior bileaflet prolapse a) MV replacement likely success: b) MV repair likey success:

a) Anterior bileaflet prolapse b) Posterior Leaflet Prolapse

Which Prosthetic Valve was the first artificial valve to be invented?

Caged ball - Starr-Edwards

Mechanical valves will present ____ ____ on Doppler.

Valve clicks. slide 14 ppt

What is the most common obstruction of prosthetic valve?

Thrombus

What technique is shown in the image?

Sliding Plasty

True/False: 35% of porcine prosthesis fail in 10-15 years due to degenration.

True

With both AVR and MVR, which chamber is obscured by shadowing?

LA

What is the most common location for Infective endocaritits. (prosthetic valve complications)

the sewing ring

Name atleast 1 antegrade flow obstruction cause.

thrombus, pannus (abnormal fibrovascular tissue usually around sewing ring), vegetations

What are the most powerful predictors of serious complications with antegrade flow obstruction.

Hx of CVA, and thrombus area of >0.8cm^2

Flow Velocity through the normal prosthetic valve will be (higher/lower) than in normal valve.

higher.

Which type of valve replacement provides 3 orifice for forward flow?

Bi- leaflet valve.

What is the complication of perforated AMVL?

Severe MR

DVI stands for ?

Doppler Velocity Index = ratio of outflow velocity to prosthetic velocity (Normal functioning Ao prothesis = 0.3 - 0.5)

10-15 mmhg

TEE becomes less common with ____ procedure TEE heavily relied upon with _____ procedure

TAVR TMVR

What procedure is done in autograft/ pediatrics? How is it done.

Ross Procedure. PV is replaced with a bioprosthetic valve and AV is replaced with the PV.

Ventricular Function, PAP, PG, EOA, prosthesis evaluation and regurge evaluation.

What is the Alfieri Technique?

Surgical technique used to treat severe MR during which a suture was placed between the A2 and P2 segments of the mitral valve. Like Mitraclip but with sutures
