Novel Transvalvular Flow Criteria Reduce Indeterminate Stress Echocardiography and Refine Risk Stratification in Low-Gradient Aortic Stenosis.
BACKGROUND Guidelines advocate the use of dobutamine stress echocardiography (DSE) in low-gradient aortic stenosis (aortic valve area [AVA] <1 cm2 with aortic valve mean gradient <40 mm Hg) with reduced left ventricular ejection fraction (<50%) for subsequent patient management. A significant proportion of patients hav...
