TAPSE indicates tricuspid annular plane systolic excursion, SPAP systolic pulmonary arterial pressure, RVEDV right ventricular end-diastolic volume, RVESV right ventricular end-systolic volume, RVEF right ventricular ejection fraction, RVSV right ventricular stroke volume, LVEF left ventricular ejection fraction
