RESUMO
Transcatheter mitral valve replacement (TMVR) has emerged as a feasible alternative to surgical reoperation in failed bioprostheses and rings. Residual mitral regurgitation following TMVR can present as a valve?in?valve paravalvular leak (PVL) and is associated with increased morbidity and mortality. Current therapies for valve?in?valve PVL are limited. We present a case of a symptomatic patient with severe valve?in?valve PVL after TMVR for a previous surgical bioprosthesis leak, who then underwent a second TMVR as a valve?in?valve?in?valve implantation with a 29 mm Edwards? SAPIEN 3 valve via transseptal approach using three?dimensional (3D) echocardiography. This unique case highlights the complexity of this clinical entity and recognizes 3D transesophageal echocardiography as a valuable tool to guide valve?in?valve PVL closures.echocardiography
