Transcatheter Aortic Valve Replacement for Degenerative Bioprosthetic Mosaic Valve

Transcatheter aortic valve in valve is an emerging alternative therapeutic intervention for patients with a failed surgical bioprosthesis in view of significant reoperative morbidity and mortality associated with redo surgery. The valve-in-valve procedure is clinically effective in vast majority of patients with degenerated bioprosthetic valves. Safety and efficacy concerns include device malposition, ostial coronary obstruction, and high gradients after the procedure. We hereby present a rare case of transcatheter aortic valve replacement valve embolization due to device malpositioning and its subsequent management.
