In participants who underwent valve-in-valve transcatheter aortic valve replacement, hypoattenuating intra-annular material within the failed surgical bioprostheses reduced the CT-derived internal area and interfered with expansion of intra-annular-positioned implanted valves, leading to postprocedural patient-prosthesis mismatch.
在接受经导管主动脉瓣置换术的患者中，失败的外科生物瓣环内的低衰减环形内材料减少了 CT 衍生的内部面积，并干扰了环形内植入瓣膜的扩张，导致术后患者-假体不匹配。
