title: Isolated effect of partial left ventriculectomy for dilated cardiomyopathy: a case report.
abstract: A 38-year-old man underwent the Batista operation to treat end-stage dilated cardiomyopathy. There was no associated mitral regurgitation, so only partial left ventriculectomy was performed. The patient recovered successfully. His New York Heart Association (NYHA) class improved from IV to I, ejection fraction increased from 8% to 37% and left ventricular diastolic dimension decreased from 89 to 68 mm. Cardiac output and stroke volume increased from 3.8 to 6.7 l/min and from 52 to 85 ml/min, respectively. This case shows the isolated positive effect of partial left ventriculectomy without mitral valve reconstruction.
