Transcatheter mitral valve replacement: design implications, potential pitfalls and outcomes assessment.

Transcatheter mitral valve replacement (TMVR) is an emerging new treatment option in patients with advanced mitral valve disease deemed a high or prohibitive risk for surgery. Designing an ideal TMVR device requires a detailed understanding of different mitral valve pathologies and the complex, dynamic anatomy and physiology of the mitral apparatus. This review aims to critically evaluate design implications in TMVR in the context of mitral valve disease, imaging prerequisites, procedural approaches, potential complications, and outcomes assessment.
