A case of quadricuspid aortic valve associated with aortic steno-insufficiency was described. A 60-year-old man who had been shown to be suffering from heart murmur was admitted to our hospital. Both aortogram and echocardiogram showed a significant aortic insufficiency with mild stenosis. The aortic valve revealed 4 cusps consisting of 3 equal cusps and a smaller cusp and it had a poor coaptation and mild calcification at each commissure. The coronary orifices were normally located. Aortic valve replacement was carried out with a 25 mm St. Jude Medical valve. Histological findings showed edematous and fibrous changes. His postoperative clinical course was uneventful. Quadricuspid aortic valve is rare and the literatures were reviewed with 33 reported cases in Japan.
本文描述了一例四叶式主动脉瓣合并主动脉瓣狭窄关闭不全的病例。一名60岁男性因心脏杂音入院。主动脉造影和超声心动图均显示存在严重的主动脉瓣关闭不全伴轻度狭窄。主动脉瓣呈现为4个瓣叶，其中3个瓣叶大小相等，另一个较小，瓣叶对合不良，各瓣叶交界处有轻度钙化。冠状动脉开口位置正常。采用25毫米圣犹达医疗瓣膜进行了主动脉瓣置换术。组织学检查结果显示有水肿和纤维化改变。他术后的临床过程平稳。四叶式主动脉瓣较为罕见，本文回顾了日本文献报道的33例病例。
