Transcatheter aortic valve implantation (TAVI) in patients with bicuspid aortic valve disease is associated with higher rates of paravalvular aortic regurgitation, which may require subsequent surgical correction. We report a case of successful late surgical CoreValve explantation 1,389 days after TAVI in a patient with bicuspid aortic valve stenosis and McArdle's disease who developed severe paravalvular aortic regurgitation. We confirm that neoendothelialization and incorporation of the nitinol cage into the aortic wall had occurred at nearly 4 years postimplantation, although explantation with careful endarterectomy could still be performed without requiring simultaneous aortic root replacement.
经导管主动脉瓣植入术（TAVI）用于治疗二叶式主动脉瓣疾病患者时，瓣周主动脉瓣反流发生率较高，可能需要后续手术矫正。我们报告了1例二叶式主动脉瓣狭窄合并麦卡德尔病患者，在TAVI术后1389天成功进行了晚期CoreValve人工瓣膜取出术，该患者出现了严重的瓣周主动脉瓣反流。我们证实，在植入近4年后，已发生了新生内膜化以及镍钛合金支架与主动脉壁融合，尽管仍可通过仔细的动脉内膜切除术进行人工瓣膜取出术，而无需同时进行主动脉根部置换。
