Background: In the study of severity of aortic stenosis many different methods derived from transthoracic echocardiography are used. Their principal limitations are left ventricular dysfunction and calcified aortic valve. The objective of this study was to assess the utility of a described echocardiographic index: the fractional shortening-velocity ratio (FSVR=FS/4 V max 2) in those patients with left ventricular systolic dysfunction. Methods: We studied 72 patients with aortic stenosis and aortic valvular area (AVA)≤2 cm 2. AVA was assessed by the Gorlin equation. Left ventricular systolic dysfunction was defined by FS≤29%. Using receiver operating characteristic curves analysis to test the predictive discrimination of patients with and without critical aortic stenosis, we studied the best FSVR value to assess aortic stenosis severity. Results: We found a significant linear correlation between AVA and FSVR ( r=0.59; P
