[Ventricular septal perforation due to coronary artery spasm--a case report].

A 70-year-old female was referred due to chest pain and cardiogenic shock. Echocardiogram showed ventricular septal perforation (VSP) with large left to right shunt. ECG indicated ischemia on the left anterior descending region. Instantaneous coronary angiogram was done under the support of IABP. Neither obstructive nor stenotic lesions were found in the coronary arteries. Coronary artery spasm was a likely cause of VSP. The patient underwent emergency surgery within 12 hours from the onset. The VSP, 2 cm in diameter, was located on the postero-apical portion of the ventricular septum. The defect was closed by endocardial patch method using an equine pericardium. Postoperative course was uneventful, and the patient was transferred 3 weeks after the operation.
