Abstract

In this study, we demonstrated the mid-term result of surgical ventricular restoration (SVR) for ischemic cardiomyopathy. Fifty-two patients (age 62 +/- 11 years) who underwent SVR between 2003 and 2010 were enrolled. Overlapping left ventriculoplasty, papillary muscle approximation, and coronary artery bypass grafting (CABG) were performed in 36 (69%), 39 (75%) and 46 (88%) patients, respectively. Preoperatively, 45 (87%) patients presented New York Heart Association (NYHA) class III/IV, whereas all patients presented NYHA I/III postoperatively (P < 0.01). left ventricular (LV) end-systolic volume index (LVESVI) and LV ejection fraction (LVEF) were improved postoperatively (LVESVI: 111 +/- 37 to 68 +/- 24, p < 0.01, LVEF : 30 +/- 9 to 37 +/- 11, p < 0.01). The degree of mitral regurgitation (MR) was 3+ or more in 27 (52%) patients, whereas 50 (96%) presented 1+ or less postoperatively (P < 0.01). The 1-, 3-, and 5-year survival rates were 90%. 83%, and 75%, respectively. Cox regression analysis demonstrated that preoperative MR 4+ was the significant predictor of postoperative death (P < 0.05, HR 5.2, 95% CI 1.2-22.9). Because of its satisfactory mid-term result, SVR would be validated as an effective procedure for ischemic cardiomyopathy.
