Embolization of a balloon expandable valve during transcatheter aortic valve implantation (TAVR) is a rare complication which generally can be managed by implantation of the embolized valve into the aorta. We present a TAVR case where the combination of an ascending aortic aneurysm and a narrow aortic arch precluded implantation of an embolized balloon-expandable valve into either the ascending and descending aorta. As a bailout strategy, the embolized valve was secured in the aortic arch using two self-expandable stents. Six month after the procedure, computed tomography confirmed a stable valve position with unobstructed blood flow into the supra-aortic arteries.
经导管主动脉瓣植入术（TAVR）期间球囊扩张瓣膜栓塞是一种罕见的并发症，通常可以通过将栓塞的瓣膜植入主动脉来处理。我们报告了一个 TAVR 病例，其中升主动脉瘤和主动脉弓狭窄的组合排除了将栓塞的球囊扩张瓣膜植入升主动脉和降主动脉的可能性。作为一种紧急备用策略，使用两个自扩张支架将栓塞的瓣膜固定在主动脉弓内。术后 6 个月，计算机断层扫描证实瓣膜位置稳定，上主动脉血流通畅。
