Valve-in-Valve in a Flail Bioprosthetic Mitral Valve With Endocarditis Using a Novel Embolic Protection Device.

A 79-year-old woman presented in cardiogenic shock with a flail bioprosthetic mitral valve leaflet and endocarditis. In the absence of other viable options, transfemoral valve-in-valve transcatheter mitral valve replacement was performed with a novel embolic protection device, resulting in trace mitral regurgitation and no neurologic complications.
