Transcatheter aortic valve implantation (TAVI) has emerged as a viable alternative endovascular technique in selected patients with severe aortic stenosis, who are either inoperable or at high risk for surgical aortic valve replacement. We report a case of delayed displacement and rotation of an aortic bioprosthesis, 43 days after successful TAVI via the transfemoral approach, with the patient surviving the subsequent open heart surgery required for device retrieval.
经股动脉途径行经导管主动脉瓣置换术(TAVI)已成为一种可行的治疗选择,适用于有严重主动脉瓣狭窄且不能手术或外科主动脉瓣置换风险高的特定患者。我们报告了一例经股动脉途径成功 TAVI 后 43 天发生的生物瓣移位和旋转的病例,患者随后成功接受了体外循环下心内直视手术以取出器械。
