Transcatheter Aortic Valve-in-Valve Procedure After Bioprosthetic Valve Failure

Bioprosthetic aortic valve failure occurs in approximately 50% to 60% of patients at 15 years after surgery. With the valve-in-valve procedure, a transcatheter aortic valve is implanted inside a bioprosthetic valve, allowing a patient to avoid a second or third sternotomy.

In this video, preprocedural invasive simultaneous left ventricular and aortic pressure tracings demonstrate an elevated transvalvular gradient consistent with severe aortic stenosis, and a baseline aortogram confirms a failing stenotic bioprosthetic aortic valve (A).

Postprocedural simultaneous left ventricular and aortic pressure tracings confirm a reduction in the transvalvular gradient, and an aortogram verifies placement of a self-expanded transcatheter valve in the previous surgical bioprosthetic valve (arrowhead) no aortic regurgitation (B).
