Abstract

For ischemic cardiomyopathy, both left ventricle (LV) reconstruction and coronary revascularization are necessary. A 58-year-old man with ischemic cardiomyopathy [end diastolic volume index (EDVI)/end systolic volume index (ESVI) = 214/157 ml/m2, ejection fraction (EF) 26%] underwent left ventricular reconstruction using endoventricular circulatory patch plasty (Dor operation) and quadruple coronary artery bypass grafting combined with endarterectomy, which was used for complete coronary revascularization. For the Dor operation, in order to minimize arrest time and to determine the purse-string suture line, palpation of contractility of the left ventricular muscle from inside under the beating heart was performed. And to avoid insufficient postoperative LV volume, a balloon was used. The surgery was performed without blood transfusion or intraaortic balloon pumping (IABP) support. Postoperative cardiac function was excellent (EDVI/ESVI = 128/68 ml/m2, EF 46%).
