Comparison of mitral valve repair vs. replacement for mitral valve regurgitation
Main finding · All-cause mortalityResult — go to the resultHazard ratio 1.32 95% CI 1.08–1.63Authors' conclusion
Among patients suitable for either surgical strategy, mitral valve repair showed better long-term survival compared to replacement, particularly in degenerative MR. However, this advantage was not observed in secondary MR.
Study context
- Population
- Patients undergoing first-time mitral valve surgery for mitral regurgitation, 2000–2021, in a cardiothoracic surgery unit in North-West Englandeligible patients undergoing first-time mitral valve surgery
- Participants

- Exposure
- Mitral valve repair compared to mitral valve replacement for mitral regurgitation (MR)
- Repairn = 1,243reference
