Transfemoral access remains the most widely used peripheral vascular approach for transcatheter aortic valve implantation (TAVI). Despite technical improvement and reduction in delivery sheath diameters of all TAVI platforms, 10-20% of patients remain not eligible to transfemoral TAVI due to peripheral artery disease. In this review, we aim at presenting an update of recent data concerning transfemoral access and percutaneous closure devices. Moreover, we will review peripheral non-transfemoral alternative as well as caval-aortic accesses and discuss the important features to assess with pre-procedural imaging modalities before TAVI.
经股动脉入路仍然是经导管主动脉瓣植入术（TAVI）最广泛使用的外周血管入路。尽管所有TAVI平台在技术上有所改进且输送鞘管直径减小，但仍有10%-20%的患者因外周动脉疾病而不适合经股动脉TAVI。在本综述中，我们旨在介绍有关经股动脉入路和经皮闭合装置的最新数据。此外，我们将回顾外周非经股动脉替代入路以及腔静脉-主动脉入路，并讨论在TAVI前使用术前成像方式评估的重要特征。
