Despite technological advancements and new generation devices availability, transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve (BAV) stenosis still presents unique technical challenges.
We report an uncommon but critical complication of acute right coronary artery occlusion resulting from valve dislocation during TAVR. For the first time, we employed novel approach, namely second valve dragging, to address mispositioned self-expanding valve. This implementation of novel and successful interventional treatment led to the rapid relief of coronary obstruction.
This innovative approach offers a promising avenue for further management of these patients in critical conditions.
尽管有技术进步和新一代设备可供使用，但经导管主动脉瓣置换术（TAVR）治疗二叶式主动脉瓣（BAV）狭窄仍面临独特的技术挑战。
我们报告了一例TAVR期间因瓣膜脱位导致急性右冠状动脉闭塞的罕见但严重的并发症。我们首次采用了一种新颖的方法，即二次瓣膜牵拉，来处理位置不当的自膨胀瓣膜。这种新颖且成功的介入治疗方法迅速缓解了冠状动脉阻塞。
这种创新方法为进一步治疗这些危急情况下的患者提供了一条有前景的途径。
