TCT-254 Very Low Intravenous Contrast Dose (20cc) Protocol for Computed Tomography Angiography (CTA) Providing Comprehensive Cardiac and Vascular Assessment for Transcatheter Aortic Valve Replacement (TAVR) in Patients with Chronic Kidney Disease (CKD)

TAVR is a lifesaving procedure for many patients at high risk for surgical aortic valve replacement. The prevalence of CKD and risk for contrast-induced nephropathy in this population is high. A very low contrast dose CTA protocol enabling comprehensive cardiac and vascular imaging would be valuable
