Impact of Fast-rotation Coronary CT in Patients Undergoing Aortic Stenosis Workup
Trial Parameters
Brief Summary
This study aims to evaluate the clinical value of a novel CT gantry supporting a .23 second rotation time and systematically compare it with 0.23 second rotation time, in patients with clinically indicated aortic CTA in the workup of aortic stenosis. Patients will be randomly assigned .23 or .28 sec rotation time CTA. Coronary artery interpretability rates will be determined in both groups.
