Premature Bioprosthetic Mitral Valve Dysfunction Due to Flail Leaflet Treated With Transcatheter Mitral Valve Replacement; a Case Report

Early bioprosthetic mitral valve failure is uncommon, but cases can present with symptomatic heart failure and require careful attention and evaluation. Transcatheter valve replacement is a minimally invasive treatment for mitral valve dysfunction that can have a considerable impact, particularly for those who are at high surgical risk or have a history of bioprosthetic valve failure. We present a rare case of significant mitral regurgitation due to the unexpected premature failure of a bioprosthetic valve that was implanted three years prior. This patient was treated with transcatheter mitral valve replacement with the implantation of an Edwards SAPIEN Ultra (Edwards Lifesciences) valve.
