Abstract

Since currently used parameters for predicting vascular complications (VCs) after transfemoral TAVR are not accurate enough, we aimed to investigate whether Iliofemoral artery lumen volume (IFV) measurement by 3D CT might be used as a screening tool. Included were 45 patients with VCs and 45 matched patients with no VC. IFV was significantly lower in patients with VC compared to patients without VC and had the most favorable receiver operating curve for the prediction of VC compared to currently accepted methods. Thus, this novel 3D based measurement may aid in the preoperative assessment before transfemoral TAVR.
