title: Left ventricular volume reduction for end-stage heart failure: intrapapillary or extrapapillary resection, mitral valve repair or replacement?
abstract: We report on two patients with end-stage dilated cardiomyopathy and functional mitral valve insufficiency who underwent left ventricular volume reduction. Intrapapillary resection and correction of the mitral valve regurgitation produced inadequate reduction of the ventricular cavity and resulted in inability to wean the patients from cardiopulmonary bypass. Following extension of the resection to include the papillary muscles and mitral valve replacement, there was a significant improvement in cardiac function. Both patients survived surgery; subsequent echocardiography provided evidence of improved myocardial function and NYHA functional class.
