Abstract

Vascular complications (VCs) are difficult to predict and remain an important issue after transfemoral (TF) transcatheter aortic valve implantation (TAVI) although their incidence has decreased with size reduction of introducers. We aimed to evaluate a standardized measurement of femoral artery depth (FAD) using computed tomography (CT) to predict VCs after TAVI. We performed a retrospective study of 679 TF TAVI patients. We evaluated a standardized CT method to measure FAD immediately above the bifurcation. Sheath-to-femoral-artery ratio (SFAR), calcification, and tortuosity were also evaluated. VCs were defined by the Valve Academic Research Consortium (VARC)-2. Receiver operating characteristic (ROC) curves were used to predict major VCs and the need for a stent-graft. The median values of FAD and SFAR were 49.0 (36.2-66.7) mm and 0.95 (0.81-1.18), respectively. Major VCs occurred in 37 (5.4%) patients and a stent-graft was required in 49 (7.1%) patients. FAD predicted the need for a stent-graft [0.61 (0.51-0.70), p=0.04] but not major VCs [0.52 (0.40-0.63), p=0.76]. In contrast, SFAR did not predict the need for a stent-graft [0.53 (0.43-0.62), p=0.61] but predicted major VCs [0.70 (0.58-0.81), p=0.001]. Calcification and tortuosity predicted neither major VCs nor the need for a stent-graft. In conclusion, the results of our study suggest that CT measurements of FAD and SFAR provide additional information to predict major VCs and the need for a femoral stent-graft after TF TAVI.
