• W2938956867 abstract "Transfemoral aortic valve implantation (TAVI) has become a viable alternative to surgical valve implantation, particularly for higher risk patients; however, vascular complications (VCs) remain a concern in transfemoral TAVI. We aimed to determine clinical and computed tomographic angiography-derived risk factors associated with Valve Academic Research Consortium (VARC)-2 criteria VCs in patients who underwent TAVI. From 2011 to 2017, 481 patients underwent percutaneous transfemoral TAVI at the Minneapolis Heart Institute and were screened for procedural and postprocedural access-related VC according to VARC-2 criteria. Clinical and clinical and computed tomographic angiography-derived data were collected to establish risk factors for VC. A total of 99 (21%) patients had VARC-2 VCs. Closure device failure (CDF) occurred in 56 of 99 (57%), minor VCs in 37 of 99 (37%), and major VCs occurred in 6 of 99 (6%). Access site-related VCs were preceded by CDF in 18 of 43 (42%) patients and the risk of major/minor VCs was 14 times greater in patients who experienced closure complications. The incidence of CDF was higher in common femoral artery (CFA) access sites with circumferential vessel wall calcification of more than 90° (p = 0.02) and when skin-surface to CFA access-site distance at an optimal access angle of 45° exceeded 80 mm (p = 0.03). In conclusion, both the degree of circumferential CFA access site calcification and distance to skin surface at an optimal access angle may improve risk stratification of access planning in patients who underwent percutaneous transfemoral TAVI.
