Background: The outcome of moderate-to-severe ischemic mitral regurgitation with multivessel coronary artery disease is still debated. We analysed the effect of different treatments, i.e. medical therapy (MT), coronary artery by-pass grafting (CABG) alone and CABG with mitral valve surgery (MVS), on the survival and rehospitalization of these patients.Methods: Between 1990 and 2002, we identified III consecutive patients, aged 73 8 years, with chronic moderate-to-severe mitral regurgitation and multivessel coronary artery disease at cardiac catheterization, in absence of primary valve disease. Twenty-two patients were treated by NIT, 50 by CABG and 39 by CABG+MVS. Overall, the median clinical and echocardiographic follow-ups were 34.9 and 14.6 months, respectively.Results: Groups differed significantly (p < 0.03) for left ventricular end-diastolic volume index (NIT 153 54, CABG 125 35, CABG+MVS 129 38, m1/m2), ejection fraction (NIT 35 14, CABG 38 13, CABG+MVS 50+14, %) and mammary artery graft use (CABG 60, CABG + MVS 74, %). While in-hospital mortality was higher in surgical patients (MT 13.6, CABG 18, CABG + MVS 17.9, %, p = 0.09), 7-years mortality showed a trend in favour of CABG + MVS compared to other groups (NIT 100, CABG 5 7, CABG + MVS 29, %, p 0.1). After adjusting for baseline differences, CABG alone or with MVS had a 5 7% (HR 0.43, p = 0.005) and 53 % (HR 0.47, p = 0.02) risk reduction of combined cardiac death and rehospitalization rate compared to MT. However, only CABG+MVS independently predicted mortality (risk reduction 65%, HR 0.35, p = 0.027).Conclusions: In moderate-to-severe ischemic mitral regurgitation and multivessel coronary artery disease, surgery reduced total cardiac events but only a concomitant MVS significantly improved survival.
