Impact of Fast-rotation Coronary CT in Patients Undergoing Aortic Stenosis Workup

Impact of Fast Gantry Rotation Cardiac CT Angiography on Coronary Motion Artifacts in the Absence of β-Blocker Premedication in Patients Undergoing Aortic Stenosis Workup: a Single-centre Randomized Controlled Trial

Important: This information is not medical advice. Talk to your doctor about whether a clinical trial is right for you.

About This Trial

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.

Who May Be Eligible (Plain English)

Who May Qualify: - Subjected to cardiac CT due to known or suspected aortic valve stenosis Who Should NOT Join This Trial: - Patients unable to hold their breath, deaf or visually impaired - Estimated glomerular filtration rate (eGFR) of \<30 mL/min - Hemodynamic instability or cardiogenic shock, Acute pulmonary edema, Exacerbated chronic obstructive pulmonary disease, Pregnant and breast-feeding women - Patients with prior coronary artery bypass grafting (CABG) - Patient incapable of discernment Always talk to your doctor about whether this trial is right for you.
