Table 1

Echocardiography exam protocol and data.

Echocardiography views	Assessment
SLAX	Extent of the pericardial effusion and diameter
SIVC	Diameter of IVC;
PLAX	IVS and LV posterior thickness; LVEDD at end diastolic
PSAX	Eyeballing evaluate LV and RV function and structure
A4CH	M-model: MAPSE, TAPSE; TDI: S-MV, S-TV; RV: LV area ratio at end diastolic; Color Doppler: E-MV, A-MV; E/e

Abbreviations: SLAX: subxiphoid long axis; SIVC: subxiphoid inferior vena cava; PLAX: parasternal long axis; PSAX: parasternal short axis; A4CH: apical four chamber; IVC: inferior vena cava; dIVC: distensibility index of the inferior vena cava; IVS: interventricular septum; LVEDD: left ventricular end-diastolic dimension; TAPSE: tricuspid annular plane systolic excursion; EF: ejection fraction; MAPSE: mitral annular plane systolic excursion; E-MV: early diastolic transmitral velocity; A-MV: late diastolic transmitral velocity; TDI: tissue Doppler imaging; S-TV: tricuspid annular peak systolic velocity; S-MV: mitral annular peak systolic velocity; E/e: early diastolic transmitral velocity to early mitral annulus diastolic velocity ratio; RV: right ventricle; LV: left ventricle; TV: tricuspid valve; MV: mitral valve.
