title: Traumatic aortic regurgitation caused by a detached commissure.
abstract: Case reports of traumatic aortic regurgitation caused by detached commissures are rare. We report a case of a 56-year-old man involved in a traffic accident. During his hospitalization for subdural hematoma and pulmonary contusion, he began to suffer from heart failure. He was operated on under diagnosis of severe aortic regurgitaion. The commissure between the left and the noncoronary cusps was largely detached from the aortic wall, which was easily estimated to be the cause of the prediagnosed left cusp prolapse. His aortic valve was replaced, and his postoperative course was uneventful.
