Mitral Transcatheter Edge-to-edge Repair: British Cardiovascular Intervention Society Position Statement.

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Severe mitral regurgitation (MR) poses significant risks, especially for patients unsuitable for traditional surgery.
• Transcatheter mitral leaflet repair (TMLR) has emerged as a viable alternative, evolving with technological advancements.
• National Institute for Health and Care Excellence (NICE) approval in 2019 highlights its clinical acceptance.

Purpose of the Study:

• To summarize current clinical evidence and indications for TMLR.
• To provide expert consensus on best practices for TMLR procedures.
• To establish standards for TMLR team composition, case volume, and data collection.

Main Methods:

• Review of randomized clinical trials and existing literature on TMLR.
• Expert panel consensus development on patient selection, procedural techniques, and post-procedure care.
• Formulation of recommendations for quality standards and data management.

Main Results:

• TMLR demonstrates established safety and efficacy for both primary and secondary MR.
• The procedure is a crucial treatment option for patients at elevated risk for conventional mitral valve surgery.
• Clinical evidence supports TMLR's role in improving outcomes for select patient populations.

Conclusions:

• TMLR is a mature, non-surgical treatment for severe mitral regurgitation.
• Expert consensus guides optimal patient selection, procedural execution, and post-procedural management.
• Standardized protocols and data collection are essential for advancing TMLR practice and patient outcomes.
