Delayed coronary obstruction is a rare but often fatal complication of transcatheter aortic valve replacement that can present within 24 hr after the transcatheter aortic valve replacement procedure. We present a case of a 77-year-old woman whose distal left main coronary artery bifurcation became obstructed by an embolized piece of native valve leaflet material 16 hours after the uncomplicated transfemoral implantation of an Edwards Sapien Ultra 23 mm aortic valve, which was successfully treated with the simultaneous kissing stent technique.

经导管主动脉瓣置换术后冠状动脉阻塞的独特原因

延迟性冠状动脉阻塞是经导管主动脉瓣置换术的一种罕见但通常是致命的并发症，可在经导管主动脉瓣置换手术后 24 小时内出现。我们介绍了一例 77 岁女性的病例，在简单的经股骨植入 Edwards Sapien Ultra 23 mm 主动脉瓣后 16 小时，左主干远端冠状动脉分叉处被一块栓塞的天然瓣叶材料阻塞采用同步接吻支架技术治疗。
