Transapical valve-in-valve aortic valve replacement has emerged as an attractive alternative for high-risk surgery in elderly patients with degenerated aortic bioprothesis. Despite recent encouraging results, further clinical investigation is required to avoid potential cases of prosthesis-aortic annulus mismatch. We report a surgical valve replacement in a high-risk patient with dysfunctional transapical, implanted aortic valve-in-valve prosthesis 1 year after implantation.
经导管主动脉瓣置换术已成为老年退行性生物瓣衰败高危患者的一种有吸引力的替代治疗方法。尽管最近的结果令人鼓舞，但仍需要进一步的临床研究来避免潜在的人工瓣-瓣环不匹配病例。我们报告了 1 例在植入经导管主动脉瓣置换术后 1 年出现功能障碍的高危患者，行外科换瓣治疗。
