Why the study?
Does retrospectively ECG-gated multi-detector row CT accurately assess valvular morphology and calcification in patients with aortic stenosis compared to surgery and echocardiography?
Population
25 patients with aortic valve stenosis and sinus rhythm prior to surgical valve replacement

Contrast-enhanced CT may improve aortic valve morphology assessment in stenosis; leaves open whether it should supplant nonenhanced protocols.
Does retrospectively ECG-gated multi-detector row CT accurately assess valvular morphology and calcification in patients with aortic stenosis compared to surgery and echocardiography?
Contrast-enhanced retrospectively ECG-gated multi-detector row CT is a reliable noninvasive tool for assessing aortic valve morphology, annulus diameter, and calcification in patients with aortic stenosis prior to surgery.
