Severe heart laceration in penetrating chest trauma: thoracoscopy as a key to diagnosis.

A patient had attempted suicide by firing a butcher's gun into his left chest 3 cm caudal to the mammilla. Transthoracic echocardiography and CT-scan showed a discrete hematopneumothorax but no pericardial effusion, the cardio respiratory condition was stable. As the bolt had been aimed directly at the heart of the patient, thoracoscopy was performed to rule out cardiac trauma. Thoracoscopy showed a distinct severe contusion of the otherwise intact pericardium and a hemopericardium. Immediate thoracotomy and pericardiotomy revealed significant intrapericardial bleeding caused by an incomplete rupture of the left ventricle. The condition was successfully treated by direct reinforced suture.
