ABSTRACT Background Access‐related vascular complications (VCs) after percutaneous transfemoral transcatheter aortic valve replacement (TAVR) are associated with poor clinical outcomes and remain a significant challenge despite technological advances. The aim of this study was to identify anatomic predictors access‐related VCs TAVR on preprocedural contrast‐enhanced multidetector computed tomography (MDCT). Aims anatomical MDCT. Methods A total 348 consecutive patients symptomatic severe AS who underwent were included retrospectively. primary endpoint the composite minor major access site as defined by Valve Academic Research Consortium‐3 (VARC‐3) criteria. population divided into two groups according VC including (+) (−). Results 101 (29%) developed (8.7% major, 20.3% minor) following TAVR. Regression analysis identified CFA calcification ( p = 0.004), depth < 0.001), minimum diameter depth‐to‐diameter ratio ≥ 5.6 sheath‐to‐femoral artery (SFAR) 0.001) VC. ROC curves generated for occurrence VC, AUC femoral (0.720) higher than SFAR (0.636, 0.630). Conclusion Complications related sites continue be concern undergoing TF‐TAVR. has demonstrated superior predictive performance compared expressed in literature. Utilizing criterion may enhance risk stratification high‐risk patients, potentially reducing morbidity mortality.
