Abstract 13853: Systolic Function and the Transvalvular Mean Gradient in Patients with Severe Aortic Stenosis: Role of Left Ventricular Twist and Longitudinal Systolic Strain

Background: In patients with severe aortic stenosis (AS) (AVA <1.0 cm2), a low transvalvular mean gradient (MG) portends a worse prognosis. A low MG is associated with a low flow state, which is of...
