According to ARRS' American Journal of Roentgenology (AJR), cardiac CTA-derived left atrium emptying fraction (LAEF) improves predictive performance of established clinical risk scores and may be used to assess patients' risk during pre-transcatheter aortic valve replacement (TAVR) workup and postprocedural surveillance. LAEF derived from preprocedural cardiac CTA independently predicts mortality in patients with severe aortic
