Fatal traumatic rupture of an aortic aneurysm of the sinus of Valsalva: an autopsy case.

摘要

This report describes an autopsy case of a rare type of aortic sinus of Valsalva aneurysm, which caused fatal rupture from a blunt chest impact. A 51-year-old male was hit in the chest with a fist, lost consciousness after about 15min and died after approximately 7h. The postmortem examination revealed a large saccular aneurysm of the right coronary sinus bulging on the right atrium, which had a full laceration causing pericardial hematoma (cardiac tamponade). A related chest wall injury was observed in the right outer mammary region. A rare type of bulging onto the right atrium and subsequent sclerosis of the right coronary artery appeared to have greatly contributed to the fatal rupture.
