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

With a valve-in-valve procedure, a transcatheter aortic valve is implanted inside a failing bioprosthetic mitral valve, allowing a patient to avoid repeat sternotomy.

This video demonstrates transseptal puncture and balloon dilation of the interatrial septum, allowing passage of a balloon-expandable transcatheter valve from the right atrium into the left atrium (A).

Deployment of the transcatheter valve replaces the degenerative bioprosthetic mitral valve (B).

A postprocedural 3D transesophageal echocardiogram demonstrates a well-seated transcatheter valve (C, left) without regurgitation on 3D color Doppler (C, right).
