Left ventricular reconstruction by endoventricular circular patch plasty repair: a 17-year experience

The first experience with endoventricular circular patch plasty (EVCPP) was reported in 1984 as a surgical method to rebuild left ventricular (LV) geometry made more spheric after myocardial infarction. The consequence is dilated ischemic cardiomyopathy. In anterior infarction, the free LV wall and septum are scarred and become dyskinetic or akinetic. The fundamental approach excludes the noncontractile (asynergy) and nonresectable regions to restore more normal size and shape. The current experience of our group in 2001, includes 1,011 patients, and confirmation of our results by others, including an international team. The basic components are LV reconstruction, revascularization, and mitral repair (when needed), which form an integrated method of surgical management. Endocardiectomy and cryoablation are used with spontaneous and inducible ventricular arrhythmias. This article reviews these results and summarizes 10 important points concerning the surgical treatment of ischemic dilated cardiomyopathy that may provide guidelines for the future. These data indicate EVCPP, and its variations, form the central theme in surgical treatment of congestive heart failure.
