INITIAL CHANGES IN PEAK AORTIC JET VELOCITY AND MEAN GRADIENT PREDICT PROGRESSION TO SEVERE AORTIC STENOSIS

We sought to examine the association between changes in peak aortic jet velocity (Vmax) and mean gradient (MG) among patients with mild or moderate aortic stenosis (AS) and risk of progression to severe disease. Adult subjects referred for echocardiography at a single academic referral center with
