title: [Optimal indication for surgical ventricular restoration for dilated cardiomyopathy].
abstract: In this study, we assessed mid-term results of surgical ventricular restoration (SVR) for dilated cardiomyopathy. The study subjects were 107 patients who underwent SVR for both ischemic (ischemic cardiomyopathy:ICM, n=57) and non-ischemic (dilated cardiomyopathy:DCM, n=50) dilated cardiomyopathy. In 49(86%)patients ICM was associated with New York heart Association(NYHA) class III or more. Preoperative left ventricular ejection fraction (LVEF) and left ventricular end-diastolic dimension(LVDd)were 22±6% and 67±9 mm, respectively. Hospital mortality was 14% and 5-year mortality was 40%. In contrast, 46( 92%) of the DCM patients presented with NYHA class III or more. Preoperative LVEF and LVDd were 20±6% and 74±9 mm, respectively. Hospital mortality was 28% and 5-year mortality was 63%. For NYHA class III or less, however, 5-year mortality rates were 23% and 39% in those with ICM and DCM, respectively. For those with NYHA functional class III or less, SVR was associated with a satisfactory survival rate and is recommended. For those with severe heart failure, however, ventricular assist devices or heart transplantation may have to be indicated.
