Partial left ventriculectomy in association with dilated cardiomyopathy: echocardiographic follow-up.
Left ventricular function after a left ventriculectomy was assessed in a patient with idiopathic dilated cardiomyopathy (DCM) who has survived longer than any other patient in Japan after this operation. The 19-year-old male had a history of cerebral infarction because of left ventricular thrombus associated with DCM. In order to remove the thrombus and improve left ventricular function, an approximately 12x4cm piece of myocardial tissue was resected according to the methods of Batista's operation. Left ventricular diastolic dimension was temporarily reduced 1 month after surgery, but increased again. During the 45 months of follow-up, left ventricular diastolic dimension, cardiac output and New York Heart Association functional class remain unchanged from the preoperative values.
