INTERVENTIONAL
Conditions
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.
Eligibility
Inclusion Criteria1
- Subjected to cardiac CT due to known or suspected aortic valve stenosis
Exclusion Criteria5
- 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
