Abstract: Background: Optimal treatment strategies for sonic patients with ischemic cardiomyopathy can be unclear. We compared the Outcome for patients treated with revascularization only or with additional ventricular reconstruction. Methods and Results: We compared 74 consecutive patients with in ejection fraction < 35% and a left end-systolic volume index > 80 mL/m(2). All patients underwent revasularization but sonic received only revascularization (group 1) and some were randomized into a group that received additional ventricular reconstruction (group 2). Preoperative and postoperative ejection fraction, end-systolic volume, mitral regurgitation, mortality, heart failure (HF) symptoms, and recurrence were compared between groups. There was 1 postoperative death in group 2 (P = .58). Preoperative ejection fraction between the groups was similar (P = .19) but it differed significantly postoperatively (P < .001). HF class (New York Heart Association) decreased more in group 2 (group 2, 2.3 +/- 0.4 versus group 1, 1.4 +/- 0.4; P < .001). Incidence of HF recurrence and rehospitalization was significantly less in group 2 (P = .028). The postoperative development of higher-grade mitral regurgitation was greater in group 1 (147 +/- 32 mL/m(2) versus 119 +/- 25 mL/m(2). p = .024). Conclusion: The outcome at midterm of coronary artery surgery alone in patients with it preoperative large left ventricle was inferior compared with the outcome achieved with additional ventricular restoration.
