Objective: To compare clinical outcomes following mitral valve repair (MVP) to those after mitral valve replacement (MVR) in patients with ischemic mitral valve regurgitation.

Materials and Methods: The authors retrospectively analyzed data of patients with ischemic mitral valve regurgitation that underwent MVR or repair concomitant with coronary artery bypass graft at Khon Kaen University’s Srinagarind Hospital and Queen Sirikit Heart Center between January 2006 and December 2016.

Results: Postoperative results, including duration of ventilator support, incidence of post-operative bleeding, arrhythmia, sepsis, stroke, ICU length of stay, and hospital length of stay, in the two groups were similar, as were early and late postoperative mortality.No patients in the MVR group experienced post-operative valve failure compared to 8% of patients in the MVP group, who had residual moderate to severe mitral valve regurgitation and required reoperation.

Conclusion: There was no significant difference in terms of survival or postoperative outcomes between the two groups. However, the MVR group had better long-term survival and lower rate of reoperation.
