Abstract

Valve-in-valve transcatheter aortic valve implantation is currently used for failed bioprosthesis. The use of a transcatheter prosthesis in a regurgitant noncalcified root implanted Medtronic Freestyle prosthesis is particularly challenging. We present a successful transaxillary valve-in-valve implantation of a self-expandable transcatheter aortic valve prosthesis in a failed Freestyle bioprothesis implanted eleven years earlier. Tips and tricks are discussed.

摘要

经导管主动脉瓣植入术目前用于生物假体功能失效的情况。在植入美敦力Freestyle假体的反流性非钙化根部使用经导管假体尤其具有挑战性。我们展示了一例成功的经腋动脉在11年前植入的失效Freestyle生物假体中进行自膨胀式经导管主动脉瓣假体瓣中瓣植入的病例。并讨论了相关技巧。
