Abstract
Background: The optimal treatment of moderate ischemic MR is a matter of debate. Some authors advocate for isolated coronary artery bypass grafting (CABG), aiming that reverse ventricular remodeling will reduce MR grade, while others argue that a concomitant mitral valve repair (MVR) or replacement gives better results. Objectives: In this study, we compare the short-term outcomes of repairing moderate ischemic mitral regurgitation by posterior annuloplasty with flexible band versus coronary revascularization alone. Patients and Methods: In the period between April 2019 and May 2020, 40 patients with moderate ischaemic mitral regurgitation (IMR) were divided in 2 groups underwent open heart surgery at Cairo university hospitals. group (A) had CABG surgery associated with MV repair by posterior annuloplasty with flexible band, while group (B) underwent CABG surgery alone. The preoperative, operative, postoperative, and 6 months follow up data of both groups were studied. Particular attention was paid to clinical findings of presence of mitral regurgitation, its nature and degree through pre- and postoperative echocardiography. Results: There was no statistically significant difference between both groups with respect to age, gender, baseline New York Heart Association class, ejection fraction, number of bypass grafts and operative times. The CABG and mitral repair group had a larger preoperative LV dimensions than the CABG without mitral repair group (Mean LVEDD 5.8 vs. 5.4 (P=0.039), mean LESD 4.25 vs. 3.77 (p=0.04)). Lengths of mechanical ventilation period, ICU stay and hospital stay were significantly higher in the CABG without mitral repair group (P<0.05)
