This is a case report of a patient who had one of the first Hufnagel ball-valve prostheses inserted in 1954 for severe aortic incompetence. He obtained relief of symptoms for 14 years before recurrence necessitated the insertion of a Starr-Edwards valve. The patients was symptom-free for another seven years before the original valve, which had been left in place, caused his death by eroding through the aorta.
这是一例关于一名患者的病例报告。该患者于1954年植入了首批Hufnagel球瓣假体之一，用于治疗严重的主动脉瓣关闭不全。在症状复发需要植入Starr-Edwards瓣膜之前，他的症状缓解了14年。在留在原位的原始瓣膜穿破主动脉导致其死亡之前，该患者又无症状生存了7年。
