Coronary occlusion is a life-threatening complication during transcatheter aortic valve implantation (TAVI) that requires immediate revascularization. Conventionally, a total of 3 catheters are required to protect the coronary ostia during TAVI: a pigtail catheter for the angiographic evaluation of valve positioning, a guiding catheter, and a TAVI delivery system. In this case series, we present a new, simplified technique for patients who require coronary protection during TAVI using a total of only 2 catheters: a guiding catheter and TAVI delivery system. This simplified technique results in a simpler procedure and reduces vascular complications in this high-risk cohort.
冠状动脉闭塞是经导管主动脉瓣植入术（TAVI）期间的一种危及生命的并发症，需要立即进行血运重建。传统上，在TAVI期间需要总共3根导管来保护冠状动脉开口：一根用于评估瓣膜定位的猪尾导管、一根引导导管和一个TAVI输送系统。在本病例系列中，我们介绍了一种新的简化技术，用于在TAVI期间需要冠状动脉保护的患者，总共仅使用2根导管：一根引导导管和TAVI输送系统。这种简化技术使手术过程更简单，并减少了这一高危人群的血管并发症。
