Simultaneous Transseptal Para-Ring Leak Closure and Transcatheter Mitral Valve Implantation for the Treatment of Surgical Mitral Repair Failure

Abstract

Repeat cardiac surgery in patients with a previous sternotomy is associated with significant morbidity and mortality. While transcatheter aortic valve implantation in high risk surgical patients is now well established, experience with transcatheter mitral valve replacement is still at an early stage. Although many successful reports of transcatheter mitral valve replacements now exist, the predominant approach has been via a transapical approach. It is likely that, as with the evolution of favoured access routes for transcatheter aortic therapies, future directions for transcatheter mitral valves will focus on smaller delivery systems favouring the transvenous transseptal approach where possible. We present the first reported case of combined transseptal para-ring leak closure followed by transcatheter mitral valve implantation using a 12/5mm Amplatzer III vascular plug and a 29mm SAPIEN 3 valve.
