Transseptal Transcatheter Mitral Valve Replacement Using Balloon-Expandable Transcatheter Heart Valves: A Step-by-Step Approach

Abstract

Transcatheter mitral valve replacement (TMVR) using balloon-expandable valves has become an alternative therapy for selected patients with mitral valve disease. Up to now, the transapical approach has been the preferred route, but the transseptal approach is becoming increasingly popular due to its reduced invasiveness and increased safety. However, transseptal TMVR procedures are technically challenging, and little is known about the screening process required before this therapy. The authors provide operators with a step-by-step approach from the screening process to follow-up care for transseptal TMVR procedures.
