A 66-year-old man was referred to our hospital for surgical treatment for aortic regurgitation. Transthoracic echocardiography revealed the diagnosis of aortic regurgitation due to quadricuspid aortic valve. During operation, we confirmed that the aortic valve consisted of 4 leaflets with almost same size (Hurwitz and Roberts classification type A). We performed valve replacement because each leaflet has degenerative change. The patient's postoperative course was uneventful and discharged the hospital without complications. Congenital quadricuspid aortic valves are rare, and patients with this disease are frequently operated because of aortic regurgitation. Presently, common operative procedure is aortic valve replacement, although in the future valvuloplasty should be investigated.
一名66岁男性因主动脉瓣反流被转诊至我院接受手术治疗。经胸超声心动图检查确诊为四叶式主动脉瓣导致的主动脉瓣反流。手术过程中，我们确认主动脉瓣由4个大小几乎相同的瓣叶组成（Hurwitz和Roberts分类A型）。由于每个瓣叶都有退行性改变，我们进行了瓣膜置换术。患者术后恢复顺利，无并发症出院。先天性四叶式主动脉瓣较为罕见，患有这种疾病的患者常因主动脉瓣反流而接受手术。目前，常见的手术方式是主动脉瓣置换术，不过未来应研究瓣膜成形术。
