  1. Values are mean ± SD or median (LQ to UQ), and % (n)
  2. PG: peak gradient, MG: mean gradient, iEOA: indexed effective orifice area, Vmax: maximum velocity across aortic valve, LVDd: left ventricular diastolic dimension, LVSd: left ventricular systolic dimension, IVSd: interventricular septal diastolic dimension, LVOT: left ventricular outflow tract dimension, LVPWd: left ventricular posterior wall dimension
