Successful repair of nonpenetrating traumatic cardiac injury is uncommon. Two cases of nonpenetrating traumatic cardiac injuries from accident are reported. Case 1. Seventy eight year old man with shock was admitted to Iida City Hospital four hours after getting a bruise by a wood block on the anterior chest wall. Soon after his arrival ultrasonic cardiography was performed because of a doubt of cardiac trauma. And it revealed cardiac tamponade. Then the emergency operation was performed. After pericardial effusion was drained, rupture on the out-flow tract of the right ventricle was found and was successfully repaired without the aid of cardiopulmonary bypass. Case 2. Sixty five year old man with left heart failure was admitted to Iida City Hospital four months after getting a bruise on left chest and back from falling. Chest and back pain was reduced three weeks after the accident, however, shortness of breath was getting worse. Ultrasonic cardiography and aortography showed aortic regurgitation. Under cardiopulmonary bypass aortic valve replacement was performed. His aortic regurgitation was caused by perforation of non-coronary cuspid due to accident. Ultrasonic cardiography is useful to make a diagnosis of nonpenetrating traumatic cardiac injury. It is necessary to operate as soon as possible in cardiac rupture, and to select valve replacement for aortic regurgitation.
