Abstract

According to the literature, the incidence of pannus formation with the St. Jude Medical prosthetic aortic valve has been reported at 0.03% and 0.14% (per patient-year), with no case report of St. Jude Medical prosthetic aortic valve malfunction due to pannus formation. Between 1980 and 1999, 1,186 patients underwent aortic valve replacement at our institute. We encountered 2 aortic valve malfunctions due to pannus formation, including the case of a 53-year-old woman who suffered a St. Jude medical aortic valve malfunction 13 years after the initial operation. A second aortic valve replacement was successful and the postoperative course was uneventful. The possibility of pannus formation on St. Jude Medical aortic valves must thus be considered and its mechanism clarified.

摘要

据文献报道，圣犹达医疗公司人工主动脉瓣形成血管翳的发生率为0.03%和0.14%（每患者年），尚无因血管翳形成导致圣犹达医疗公司人工主动脉瓣功能障碍的病例报告。1980年至1999年期间，我院有1186例患者接受了主动脉瓣置换术。我们遇到了2例因血管翳形成导致的主动脉瓣功能障碍，其中1例为一名53岁女性，在初次手术后13年出现圣犹达医疗公司主动脉瓣功能障碍。第二次主动脉瓣置换手术成功，术后过程顺利。因此，必须考虑圣犹达医疗公司主动脉瓣上形成血管翳的可能性，并阐明其机制。
