Left ventricular volume reduction for end-stage heart disease

Partial left ventriculectomy (PLV) was recently introduced for end-stage di lated cardiomyopathy to improve ventricular function. Since November 1996 w e have performed PLV in 14 patients; preoperatively 4 patients had idiopath ic dilated cardiomyopathy and 10 had ischemic dilated cardiomyopathy. 57.1% of patients were in New York Heart Association functional Class IV. The mi tral valve was replaced in 11 patients. Postoperative echocardiography show ed a reduction of left end-diastolic diameter (55.4 +/- 5.4 mm) and an incr ease in forward ejection (cardiac index from 2.19 +/- 0.571 min/m(2) to 2.6 7 +/- 0.931/min/m(2)). The 30-day mortality was 28.6% and 20-month survival was 57.2%. Only one patient was not in NYHA functional class due to postop erative progressive mitral incompetence. Prognostic factors should be ident ified to avoid early failure. However, even if the mortality rate for PLV h igh, this operation is a valid choice for the treatment of end-stage dilate d cardiomyopathy.
