TCT-125 Evaluation of EKG-gated and Dual Source Accelerated Computed Tomography Imaging Protocols for Transcatheter Aortic Valve Sizing

Procedure success for Transcatheter aortic valve replacement (TAVR) relies heavily on volumetric reconstruction imaging, particularly of EKG-gated multi-detector computed tomography (MDCT). With emerging data supporting TAVR in younger and lower-risk patients, radiation exposure becomes a valid
