Batista introduced the partial left ventriculectomy (PLV), which is based on physics alone. With experience, it has been found that the extent of myocardial disease and viability of retained muscle is an important determinant of early and late survival. Although the PLV has been almost abandoned in many countries following the negative message from the Cleveland Clinic, it is still alive in Japan with a refined concept, surgical technique and patient selection. In a series of 63 patients undergoing PLV for idiopathic dilated cardiomyopathy since 1996, operative mortality was 9.5%, and 1-, 3- and 5-year survival rates were 71.1%, 56.2% and 45.9%, respectively. Improved survival has obtained by using appropriate patient selection and concomitant restrictive mitral annuloplasty (1-, 3- and 5-year survival rate =86.5%, 78.6% and 59.4%, respectively, in the most recent 33 patients). Because of insufficient availability of donors for heart transplantation, nontransplant cardiac surgery for medically refractory heart failure is important. Ventricular restoration procedures, including PLV, should be seriously considered as an important option for endstage heart failure.
