OBJECTIVES: Ischemic mitral regurgitation (IMR) is a common finding following myocardial infarction or ischemia. Management of moderate IMR is still a hot topic. Adding mitral valve repair (MVr) to coronary artery bypass grafting (CABG) is questionable. The goal of this study was to assess and compare short-term clinical and echocardiographic results of moderate IMR treated by CABG alone versus another group of patients treated by CABG plus MVr.
METHODS: Eighty consecutive patients with ischemic heart disease (IHD) and moderate IMR were divided randomly into two equal groups: group I (40) had only CABG and group II (40) had CABG plus MVr. Patients were evaluated at 1-week, 3-months and 1-year intervals postoperatively.
RESULTS: After 1-year follow-up, our study revealed statistically significant improvement in the grade of mitral regurgitation (MR) in group II than group I. The mean value for effective regurgitant orifice area (EROA) was 0.22 ± 0.13 for group I versus 0.03 ± 0.03 for group II (P = 0.001) and for vena contracta (VC), it was 3.8 ± 2.24 for group I versus 0.4 ± 0.49 for group II (P = 0.000). There was also a significant reduction in the New York Heart Association (NYHA) functional class in both groups.
CONCLUSIONS: MVr can be performed safely and concomitantly with CABG in patients having moderate IMR, and its addition to CABG have significant short-term impact on clinical or echocardiographic outcome of patients.
