[Surgical treatment of ishemic mitral regurgitation: repair, replacement or revascularization alone?].

Introduction: Treatment of ischemic mitral regurgitation in patients that require revascularization of myocardium is still debatable.

Objective: The aim of this study was to compare three surgical approaches: valve repair and revascularization; valve replacement and revascularization, and revascularization alone.

Methods: In 2006 and 2007 at the Institute for Cardiovascular Diseases, Clinical Centre of Serbia, Belgrade, 1,040 patients with coronary disease underwent surgery. Forty-three patients (4.3%) had also mitral insufficiency 3-4+. The patients were examined clinically, echocardiographically and haemodynamically. In group I there were 14 (32.3%) patients, in group II 16 (37.2%) patients and in group III 3 (30.5%) patients. Ninety-three per cent of patients were classified as New York Heart Association (NYHA) class III and IV, and three (7%) patients had congestive heart weakness with ejection fraction < or =30%. The decision as to surgical procedure was made by the surgeon. Postoperatively, patients were checked clinically and echocardiographically after 3, 6 and 12 months. The follow-up period was approximately 15 months (8-20).

Results: Hospital mortality for the whole group was 6.9% (3 patients). In group I mortality was 14.2% (2 patients), in group II 6.25% and in group III there was no mortality. Long term results, up to 15 months, showed 100% survival in groups I and II, and in group III one patient died (7.7%).

Conclusion: Short term results upto 30 days were best in group III, but longer term results were better in groups I and II.
