A 55-year-old man underwent insection of a Hufnagel valve into his descending thoracic aorta for aortic valve insufficiency 18 years ago. He remained asymptomatic for 16 years. Because of progressive left ventricular failure his incompetent aortic valve was replaced with a De Bakey carbon ball aortic valve prosthesis 2 years later. Currently, 21 months after the operation, he is doing well with two aortic valves. Review of the literature suggests that he is the first patient reported with two aortic valves functioning concomitantly and one of the longest surviving patients with a Hufnagel valve.
18年前，一名55岁男性因主动脉瓣关闭不全接受了Hufnagel瓣膜植入降主动脉手术。他有16年无症状。两年后，由于进行性左心室衰竭，他功能不全的主动脉瓣被替换为De Bakey碳球主动脉瓣假体。目前，术后21个月，他两个主动脉瓣功能良好。文献回顾表明，他是首例报道的两个主动脉瓣同时发挥功能的患者，也是使用Hufnagel瓣膜存活时间最长的患者之一。
