Abstract
Background Cardiac magnetic resonance (CMR) imaging is the reference standard to assess right ventricular (RV) volumes and ejection fraction. However, 2-D echocardiography is commonly used for routine assessment of the RV and a number of quantitative measures have been recommended to evaluate systolic function. Measurement of right ventricular ejection fraction (RVEF), which is a key predictor of outcomes in a range of right heart diseases, is not recommended because of the limitations of 2-D imaging of the RV. Instead Fractional Area Change (FAC %)by 2-D Echocardiography and tricuspid annular plane systolic excursion (TAPSE) are recommended as surrogate measures of RV global systolic function. The aim of our study is to compare the conventional parameters of RV systolic function currently used by 2-D echocardiography with RVEF and stroke volume (SV) measured by CMR.

A total of 125 consecutive patients who consented for the CMR registry at Piedmont Heart Institute were reviewed for this study. 72 patients with adequate RV function assessment by 2D echocardiography and CMR were included. 2-D echocardiography RV FAC (%), and tricuspid annular plane systolic excursion (TAPSE) measurements were compared with CMR RVEF (%) and SV
