[Ventricular septal perforation due to weak blunt chest trauma; report of a case].
We report a 67-year-old female patient with ventricular septal perforation after weak blunt chest trauma. She tumbled down on a frozen street. Approximately 1 week later, the patient was aware of shortness of breath on exertion. On admission, holosystolic murmur was detected on chest wall and routine electrocardiogram examination showed ST-T change which suggested myocardial ischemia. Acute myocardial infarction and ventricular septal defect with left-to-right shunt was suspected. The echocardiography and cardiac catheterization revealed the muscular type ventricular septal perforation near the apex with large left-to-right shunt flow (82% shunt ratio). The congestive heart failure was controlled successfully by conservative medical treatment. Surgical repair was scheduled on the 28th day after initial chest trauma because of large left-to-right shunt. A hole of about a diameter of 2 cm with fibrous edge of the muscular septum was closed through a left ventriculotomy using a Dacron patch under cardiopulmonary bypass. Postoperative course was uneventful and the patient was discharged without symptoms of congestive heart failure.
