Why the study?
Do echocardiographic indices of right ventricular systolic function (TAPSE, RV S', RV FAC) accurately reflect right ventricular ejection fraction as measured by cardiac magnetic resonance?

This study aims to validate alternative echocardiographic indices of right ventricular systolic function against the gold standard of cardiac magnetic resonance.
Echocardiographic RV indices should not yet guide management; leaves open their correlation with CMR-derived RVEF.
Right ventricular ejection fraction (RVEF) is an important predictor of outcome in heart failure patients. Although cardiac magnetic resonance (CMR) assessment of RV function is considered gold standard and echocardiographic measurement of RVEF is challenging due to its unique geometry; CMR still has limited availability in the wider community. Therefore alternative echocardiographic indices such as tricuspid annular plane systolic excursion (TAPSE), peak tricuspid annular systolic velocity (RV S’) and RV fractional area change (RV FAC) have been evaluated and demonstrated prognostic value, however, comparison studies with RVEF by CMR are limited.
