Crossover balloon occlusion technique (CBOT) has been proposed to ensure adequate closure of the arterial access used for transcatheter aortic valve replacement (TAVR). However, the CBOT performed through the contralateral femoral artery could be challenging in cases of excessively tortuous and calcified vessels or in the presence of narrow iliac carina angles. We describe a novel technique to facilitate the advancement the peripheral balloon through the contralateral femoral artery up to the target iliofemoral system in order to facilitate access site hemostasis. The present “locking and drugging” technique takes advantages from two mechanical aspects: (a) the locking of the 0.018″ wire between the vessel wall and the TAVR delivery system or the dedicated sheath, which facilitate the crossover of the balloon in the contralateral iliofemoral system, preventing its prolapse into the aorta at the carina level and (b) the dragging of the balloon advanced into the contralateral iliofemoral system during the retrieve of the TAVR delivery system or the dedicated sheath.

“锁定和拖动”技术是一种便利的交叉球囊闭塞技术,用于经导管主动脉瓣置换术中复杂的髂股解剖结构

已经提出了交叉球囊闭塞技术 (CBOT),以确保用于经导管主动脉瓣置换术 (TAVR) 的动脉通路充分闭合。然而,在过度弯曲和钙化血管或存在狭窄的髂骨隆突角的情况下,通过对侧股动脉进行 CBOT 可能具有挑战性。我们描述了一种新技术,以促进外周球囊通过对侧股动脉到达目标髂股系统,以促进进入部位止血。目前的“锁定和给药”技术从两个机械方面利用了优势:(a) 将 0.018" 线锁定在血管壁和 TAVR 输送系统或专用鞘之间,
