Comparison of mitral valve repair vs. replacement for mitral valve regurgitation.

ABSTRACT:

Background

Mitral regurgitation (MR) is a prevalent valvular abnormality categorized as primary or secondary based on aetiology. Surgical intervention, particularly mitral valve repair, is often preferred over replacement due to its association with better outcomes. However, the benefits of repair vs. replacement, especially in secondary MR, remain debated.

Objectives

This study aims to evaluate the long-term survival and reoperation rates in patients undergoing mitral valve repair compared to mitral valve replacement for MR in a cardiothoracic surgery unit in North-West England and in subgroups with degenerative and secondary aetiology.

Methods and results

We analysed 1724 eligible patients undergoing first-time mitral valve surgery (repair: n = 1243; replacement: n
