Abstract Background Acceleration time to ejection time ratio (AT/ET) prolongation is associated with increased mortality in patients with aortic stenosis (AS). Purpose To identify the determinants associated with increased AT/ET. Methods The relationships between AT/ET ratio, clinical and Doppler ec...

Zusammenfassung:Abstract Background Acceleration time to ejection time ratio (AT/ET) prolongation is associated with increased mortality in patients with aortic stenosis (AS). Purpose To identify the determinants associated with increased AT/ET. Methods The relationships between AT/ET ratio, clinical and Doppler echocardiographic variables of interest in the setting of AS were studied in 1107 patients with AS and preserved left ventricular (LV) ejection fraction (EF), with Computed Tomography – Aortic Valve Calcium (CT-AVC) score studied in a subgroup of 342 patients. Results In univariate analysis, AT/ET ratio did correlate with aortic peak velocity (Vmax, r=0.57, p
