Isolated reoperative tricuspid valve replacement is one of the highest risk operations classified in the Society of Thoracic Surgeons registry, particularly in the setting of preexisting right ventricular dysfunction. Transcatheter tricuspid valve-in-valve implantation represents an attractive alternative to redo surgery in patients with tricuspid bioprosthetic valve degeneration who are considered high-risk or unsuitable surgical candidates. In this review article, the authors discuss the emergence of transcatheter tricuspid valve-in-valve therapy, preprocedural echocardiographic assessment of tricuspid bioprosthetic valve dysfunction, periprocedural imaging required for tricuspid valve-in-valve implantation, and postprocedural assessment of tricuspid transcatheter device function.

孤立的三尖瓣再造手术是胸外科医师学会登记的最高风险手术之一，特别是在已存在的右心功能不全的情况下。经导管三尖瓣瓣膜植入是三尖瓣生物人工瓣膜变性患者的重做手术的一种有吸引力的替代方法，这些患者被认为是高风险或不合适的手术对象。在这篇综述文章中，作者讨论了经导管三尖瓣瓣膜治疗的出现，对三尖瓣生物修复瓣膜功能障碍的术前超声心动图评估，对三尖瓣瓣膜植入术所需的围手术期成像以及对三尖瓣经导管装置功能的手术后评估。
