Data expressed as median (IQR). DTI indicates Doppler tissue imaging; IVS, interventricular septum end‐diastolic thickness; LA, left atrial; LVEDD, left ventricular end diastolic diameter; LVEDDi, indexed left ventricular end diastolic diameter; LV, left ventricular; PW, posterior wall end‐diastolic thickness; RV, right ventricular; and TAPSE, tricuspid annular plane systolic displacement.
