Clinical review reveals evolving indications and procedural barriers in transcatheter mitral valve replacement, highlighting therapeutic pathways for high-risk surgical candidates.
Key Points
To evaluate the current clinical landscape, procedural challenges, evolving indications, and prospective advancements in transcatheter mitral valve replacement (TMVR).
Narrative synthesis of clinical trial data, registry outcomes, and technological iterations for TMVR systems.
Evaluation of anatomical and technical complexities, including valve-in-valve, valve-in-ring, and native mitral valve replacement strategies.
Procedural success is significantly constrained by anatomical hurdles, predominantly left ventricular outflow tract obstruction and complex mitral annular calcification.
Transseptal delivery platforms demonstrate favorable feasibility over transapical routes, expanding eligible populations among high-risk surgical candidates.
Evolving device iterations demonstrate improved sealing mechanisms and lower profiles, aiming to reduce paravalvular leak and vascular access complications.
