Transcatheter mitral valve chord repair

Area of Science:

• Cardiology
• Cardiac Surgery
• Interventional Cardiology

Background:

• Mitral valve disease diagnosis and management are rapidly evolving.
• Degenerative mitral regurgitation (MR) is common in the West, leading to reduced survival if untreated.
• Surgical repair is the standard of care for degenerative MR, with excellent outcomes in specialized centers.

Purpose of the Study:

• To review long-term surgical outcomes of mitral valve repair using artificial chordae.
• To discuss emerging transcatheter chordal repair devices for degenerative MR.
• To highlight advancements in diagnosis and treatment of mitral valve disease.

Main Methods:

• Review of current literature on surgical and transcatheter mitral valve repair techniques.
• Analysis of outcomes for artificial chordae repair and transcatheter chordal replacement devices.
• Focus on degenerative MR, patient selection, and evolving interventional techniques.

Main Results:

• Successful surgical repair in specialized centers exceeds 95% with <1% mortality.
• Transcatheter mitral valve repair, including chordal replacement, shows promise for high-risk patients.
• Multimodality imaging improves early diagnosis and treatment planning.

Conclusions:

• Surgical repair remains the gold standard for degenerative MR.
• Transcatheter chordal repair is a viable option for select high-risk patients.
• Future advancements will focus on interventional techniques and improved patient selection for degenerative MR.
