ΔSV, The difference value between right ventricular stroke volume and left ventricular stroke volume; TAPSE/MAPSE, the ratio of tricuspid annular plane systolic excursion to mitral annular plane systolic excursion; E/e’, the ratio of early diastolic peak flow velocities of the mitral valve to peak diastolic velocities of the mitral annulus at septal and lateral; LAA-V, variation of left atrial area; LUS, lung ultrasound.
