Among various baseline echocardiographic factors, E/e’ was significantly higher for patients who developed IRAF. RA: right atrial. RV: right ventricular. Frac Area Change: fractional area change. RVSP: right ventricular systolic pressure. TAPSE: tricuspid annular plane systolic excursion. TR Vmax: tricuspid regurgitation maximal velocity. Tricuspid S’: tricuspid annular peak systolic velocity. LAVI: left atrial volume indexed. E decel time: E deceleration time. LVEF: left ventricular ejection fraction. LV GLS: left ventricular global longitudinal strain.
