[A case of isolated congenital left ventricular diverticulum]

Abstract

Isolated congenital diverticulum of the left ventricle is a rare malformation. A 2-year-old boy was admitted to our hospital for evaluation of heart murmur. The echocardiogram and MRI showed an extra cavity communicating with the left ventricle. The diagnosis was made by LV angiography. He was diagnosed as having congenital isolated diverticulum of the left ventricle without other cardiac anomalies. He received resection of the diverticulum under cardiopulmonary bypass. Histological examination showed a fibrous diverticulum. Postoperative clinical course was uneventful. We can expect good prognosis after resection of the congenital diverticulum of the left ventricle, if necessary under cardiopulmonary bypass.
