A case of quadricuspid aortic valve is described. A 43-year-old man admitted because of chest oppression on exercise. He had a ejection systolic murmur and decrescendo diastolic murmur. Electrocardiogram revealed severe left ventricular hypertrophy. Echocardiogram showed dilated left ventricle and supernumerary cusp between the right and left coronary cusp. Aortogram revealed quadricuspid aortic valve with grade 4 aortic regurgitation. At operation, quadricuspid aortic valve in which supernumerary cusp between right and left coronary cusp was smaller was found. Four cusps were excised and replaced with 23 mm Medronic-Hall prosthesis. His postoperative course was uneventful. Quadricuspid aortic valve has been extremely rare. Twenty operative cases has been reported. The clinical feature was presented.
本文描述了一例四叶式主动脉瓣病例。一名43岁男性因运动时胸部憋闷入院。他有喷射性收缩期杂音和递减型舒张期杂音。心电图显示严重左心室肥厚。超声心动图显示左心室扩张，左右冠状动脉瓣叶之间有多余瓣叶。主动脉造影显示四叶式主动脉瓣伴4级主动脉反流。手术中发现左右冠状动脉瓣叶之间多余瓣叶较小的四叶式主动脉瓣。切除四个瓣叶，用23毫米美敦力-霍尔人工瓣膜置换。他术后恢复顺利。四叶式主动脉瓣极为罕见。已报道20例手术病例。本文介绍了其临床特征。
