Transcatheter aortic valve implantation is increasingly used to treat bioprosthetic degeneration. Valve-in-valve technique has been performed successfully to treat homograft, stentless, and stented bioprosthetic dysfunction. The presence of a prosthesis in the mitral position can make the transcatheter aortic valve implantation procedure challenging due to proximity of the mitral and aortic annuli. We describe the case of a 66-year-old who underwent the first successful implantation of Edwards Sapien device in a failing homograft in the presence of a mechanical mitral valve prosthesis.
经导管主动脉瓣植入术越来越多地用于治疗生物瓣退行性病变。经导管主动脉瓣植入术（Valve-in-valve）技术已成功用于治疗同种带瓣移植、无支架瓣和支架瓣生物瓣功能障碍。二尖瓣位置的假体存在会使经导管主动脉瓣植入术变得具有挑战性，因为二尖瓣和主动脉瓣环较近。我们描述了一位 66 岁患者的病例，该患者在存在机械二尖瓣假体的情况下，首次成功地在衰竭的同种带瓣移植中植入了爱德华兹·萨皮恩（Edwards Sapien）装置。
