[Surgical treatment of aortic valve regurgitation due to nonpenetrating trauma of the chest--a case report and review of the literature in Japan].

: A case report and a literature review of the patients in Japan who underwent surgical treatment of an aortic valve regurgitation due to nonpenetrating chest trauma are presented. A 70-year-old man was admitted to our hospital with multiple trauma, including fracture of sternum, caused by traffic accident. After treatment of respiratory and circulatory failure, he was found to have aortic regurgitation and subsequent congestive heart failure. The aortic valve replacement was performed and his postoperative course was good. The tear of aortic valve was detected in the noncoronary cusp, and the size of the tear was 4 mm. The aortic valve was not recognized the findings of inflammatory or rheumatic changes. Before this case, 15 cases were operated in Japan with the diagnosis of traumatic aortic regurgitation. We reviewed them in the table.
