Abstract

The implanted first-generation Björk-Shiley valve in our patient was functioning well before aortic surgery, but we replaced the valve because we confirmed disc erosion 39 years after implantation during the surgery. We judged that the implanted valve was no longer capable of maintaining the patient's life.

摘要

我们患者体内植入的第一代Björk-Shiley瓣膜在主动脉手术前功能良好，但在手术中我们证实植入39年后出现瓣盘侵蚀，因此更换了瓣膜。我们判断植入的瓣膜已无法维持患者的生命。
