Batista Procedure

The Batista procedure, also called partial left ventriculectomy, was an experimental cardiac surgery designed to treat end stage dilated cardiomyopathy that had not responded to standard medical therapy, in which a slice of living tissue was removed from an enlarged heart and the remaining beating heart was stitched together to improve the contraction of the left ventricle. Brazilian cardiac surgeon Randas Batista invented the procedure in 1994, initially for patients with non ischemic dilated cardiomyopathy, many of whom had Chagas disease, but later research, particularly at the Cleveland Clinic, found high failure rates, with only 26 percent of patients event free and 60 percent surviving at three years. The procedure is no longer recommended and has been removed from heart failure treatment guidelines in most of the world, though a 2015 review noted some continued success in Japan under strict patient selection.
