4.19 Patient Prosthesis Mismatch and Prosthetic Valve Stenosis

In this episode, we review patient-prosthesis mismatch (PPM) and prosthetic valve stenosis. What cutoffs for indexed effective orifice area (EOA) suggest severe, moderate, or mild PPM of an aortic valve prosthesis? What about for mitral valve prosthesis? What are the causes of prosthetic valve stenosis? How do you differentiate PPM from prosthetic valve stenosis using Doppler velocity index (DVI), acceleration time, and jet contour? What factors determine whether prosthetic valve stenosis should be treated with a transcatheter valve-in-valve procedure (ViV TAVR) versus reoperation? What factors determine whether prosthetic valve thrombosis should be treated with anticoagulation only, or additional fibrinolysis versus surgery? Tune in for answers to these questions.
