[Isolated rupture of the ventricular septum caused by nonpenetrating trauma--a case report of operation in acute stage].

We experienced a case of the isolated ventricular septal defect due to nonpenetrating chest trauma. The patient was 22-year-old male who hit his chest with a steering wheel on car accident. The echocardiogram examined on the next day revealed a ventricular septal defect. Four days after the injury, intracardiac repair was performed. On cardiopulmonary bypass the ventricular perforation (35 x 35 mm size) located in the muscular portion near the apex was closed with a PTFE and equestrian pericardial patch. Postoperative cardiopulmonary function could improve enough to wean from IABP and respiratory support. However, the patient died on the fifth postoperative day of severe hepatic failure due to profound shock persisted after the accident.
