Why the study?
Which echocardiographic parameter most accurately detects impaired right ventricular ejection fraction compared to cardiac magnetic resonance imaging in a broad clinical population?
Which echocardiographic parameter most accurately detects impaired right ventricular ejection fraction compared to cardiac magnetic resonance imaging in a broad clinical population?
Peak systolic velocity (S') <11 cm/s and RV MPI >0.50 are the most accurate echocardiographic parameters for detecting moderately and severely reduced RV ejection fraction, respectively, compared to MRI.

May aid RV assessment on echocardiography; leaves open prospective outcome validation before changing practice.
