Abstrakt:	Purpose: To evaluate the efficacy of left ventriculectomy, on a short term basis, as a treatment for patients with end-stage heart failure. Methods: From February to June 1995, 7 patients with end-stage heart failure underwent partial left ventriculectomy. Before the surgical procedure, 7 (100%) patients were in functional class IV. Three (42%) patients needed inotropic support for hemodynamic stability. The mean daily dose of furosemide was l48.67 +/- 128.27 mg, of captopril 87.50 +/- 95.20 mg and of digoxin 0.23 +/- 0.04. Mean left ventricular diastolic dimension determined by 2-D echocardiography was 78.29 +/- 12.63 mm, mean left ventricular ejection fraction, determined by radionuclide ventriculography, was 0.15 +/- 0.05 whereas mean transpulmonary gradient and pulmonary vascular resistance in Wood units, determined by right heart catheterization, were 16.80 +/- 8.80 and 6.57 +/- 3.22, respectively. Results: Sixty days after the surgery, the mean functional class was 1.71 +/- 0.48 (p = 0.009), the mean left ventricular diastolic dimension 64.67 +/- 11.41 mm (p = 0.02) and the mean left ventricular ejection fraction 0.22 +/- 0.04 (p = 0.02). Conclusion: The left ventriculectomy is a promising treatment for patients with end-stage heart failure.
