Percutaneous Mitral Valve Interventions (Repair): Current Indications and Future Perspectives

Area of Science:

• Cardiology
• Interventional Cardiology
• Valvular Heart Disease

Background:

• Mitral regurgitation (MR) is the most prevalent valvular heart disease in adults, associated with substantial morbidity and mortality.
• MR etiology is categorized as primary or secondary, necessitating accurate diagnosis for optimal treatment.
• Transcatheter mitral valve repair (TMVR) is an emerging minimally invasive approach for specific patient groups.

Purpose of the Study:

• To review the etiologies and pathophysiology of acute and chronic severe MR.
• To compare transcatheter mitral valve intervention strategies, focusing on MitraClip safety, efficacy, and patient selection.
• To explore emerging percutaneous mitral valve therapies beyond current devices.

Main Methods:

• Review of existing literature on MR etiologies and management strategies.
• Comparative analysis of transcatheter mitral valve repair (TMVR) devices, particularly MitraClip.
• Discussion of clinical trial data regarding TMVR in primary and secondary MR.

Main Results:

• TMVR has demonstrated success in reducing symptoms, morbidity, and improving quality of life in selected MR patients.
• TMVR shows potential for reverse remodeling and survival benefits, especially in secondary MR.
• Ongoing research and trials are refining patient selection and timing for percutaneous interventions.

Conclusions:

• Accurate MR etiology identification is crucial for guiding treatment decisions.
• Transcatheter mitral valve repair is a safe and effective option for carefully selected patients.
• Further research into novel percutaneous mitral valve therapies is warranted to expand treatment options.
