Studies of patients undergoing transfemoral TAVI with MDCT were included.

Data on study cohort, procedural characteristics and significant predictors of vascular complications were extracted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified 23 original studies involving 8697 patients who underwent TAVI between 2006 and 2020. Of all patients, 8514 (97.9%) underwent percutaneous transfemoral\u2010TAVI, of which 8068 (94.8%) had contrast\u2010enhanced MDCT. The incidence of major vascular complications was 6.7\u2009\u00b1\u20094.1% and minor vascular complications 26.1\u2009\u00b1\u20097.8%. Significant independent predictors of major and minor complications related to vessel dimensions were common femoral artery depth (&gt;54\u2009mm), sheath\u2010to\u2010iliofemoral artery diameter ratio (&gt;0.91\u20131.19), sheath\u2010to\u2010femoral artery diameter ratio (&gt;1.03\u20131.45) and sheath\u2010to\u2010femoral artery area ratio (&gt;1.35). Substantial iliofemoral vessel tortuosity predicted 2\u20135\u2010fold higher vascular risk. Significant iliofemoral calcification predicted 2\u20135\u2010fold higher risk. The iliac morphology score was the only hybrid scoring system with predictive value.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Independent iliofemoral predictors of access\u2010site complications in TAVI were related to vessel size, depth, calcification and tortuosity.
