As assessed by tissue Doppler velocities, longitudinal contraction is commonly altered at an earlier stage than radial contraction in patients with severe aortic stenosis (AS). However, its relationship to exercise tolerance or to prognosis has not been clearly established. By using two-dimensional (2D) echocardiographic strain, we sought to evaluate values of deformation components in the setting of severe AS and to correlate these values with exercise tolerance and with patients' outcome.
