    Abstract:
    BACKGROUND: Because of the scarcity of donor hearts, surgical alternatives to heart transplantation, such as partial left ventriculectomy (PLV), were introduced for treatment of advanced heart failure. Here, we report our experience with this procedure performed in combination with mitral valve repair. METHODS: Twelve patients with dilated cardiomyopathy (DCM), New York Heart Association (NYHA) class exceeding III on maximal medical therapy, cardiac index of 2.5 liter/min/m2 or less, VO2max of 14 ml/kg/min or less, left ventricular end-diastolic diameter (LVEDD) of 7.0 cm or more, and grade II or greater mitral incompetence, were selected for PLV and mitral valve reconstruction (MVR). Echocardiography, hemodynamics, spiroergometry, and clinical assessment were performed before and 1 year after the operation. RESULTS: One-year survival was 83.3%. All 10 surviving patients were free from failure of the procedure 1 year post-operatively. From pre-operatively to 1 year post-operatively, NYHA functional class improved from 3.3 +/- 0.3 to 1.9 +/- 0.2 (p < 0.001), cardiac index increased from 2.0 +/- 0.2 liter/min/m2 to 2.9 +/- 0.2 liter/min/m2 (p < 0.001), stroke volume index from 25.9 +/- 4.8 ml/m2 to 40.3 +/- 7.3 ml/m2 (p = 0.008), and VO2max from 10.9 +/- 2.4 ml/kg/min to 16.0 +/- 3.6 ml/kg/min (p = 0.016), whereas LVEDD decreased from 8.4 +/- 0.6 cm to 6.6 +/- 0.3 cm (p < 0.001), left ventricular end-systolic diameter from 6.8 +/- 0.8 cm to 5.3 +/- 0.5 cm (p < 0.001), and mitral incompetence from 2.4 +/- 0.6 to 0.9 +/- 0.6 (p < 0.001). Pulmonary pressures and fractional shortening did not change significantly (p > 0.05). Four patients received an implantable cardioverter/defibrillator as a result of their pathologic electrophysiologic examination. CONCLUSIONS: In carefully selected patients, PLV combined with MVR achieves short-term results comparable to that after heart transplantation. However, long-term results and multicenter evaluation will be needed to define its place in the treatment of advanced heart failure.
