1. Box plot showing percentage change in early diastolic pulsed-Doppler mitral inflow (E)/early diastolic tissue Doppler velocity (E´) from pre– to post–balloon aortic valvuloplasty echocardiograms comparing patients with residual aortic stenosis gradient on follow-up echocardiogram ≤40 mm Hg with patients with residual AS gradient >40 mm Hg. Boxes represent interquartile range, dark line represents median value, and whiskers represent range.
