Structural prosthetic valve deterioration and nonstructural dysfunction are two common causes of nonfatal valve events following implantation of a bioprosthetic valve. Using caution and skill, implantation of a bioprosthesis is relatively easy. On the other hand, explantation of a bioprosthesis is a challenging and time-consuming procedure. We have developed a surgical technique by which we were able to ameliorate this troublesome situation in a 79-year-old man with aortic stenosis in whom we had to intraoperatively explant the bioprosthesis that we have put in initially. Another bioprosthesis of the same kind was used to replace the old prosthesis with the rest of his postoperative course until dismissal being eventless.
结构性人工瓣膜退化和非结构性功能障碍是生物人工瓣膜植入后非致命性瓣膜事件的两个常见原因。谨慎操作且技术熟练的话，生物人工瓣膜的植入相对容易。另一方面，生物人工瓣膜的取出是一个具有挑战性且耗时的过程。我们开发了一种手术技术，通过该技术，我们成功改善了一名79岁主动脉狭窄男性患者的棘手情况，该患者术中必须取出我们最初植入的生物人工瓣膜。我们使用了另一个同种生物人工瓣膜来替换旧瓣膜，其术后恢复过程直至出院均无异常。
