Comparison of conventional echocardiographic parameters of RV systolic function with cardiac magnetic resonance imaging

چکیده
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.

Introduction 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 echocardiograph...

Results RV function measured by CMR was negatively correlated with peak systolic strain of mid RV free wall (P=0.038, Pearson r=-0.357) and also negatively correlated to both mean of strain (P=0.028, Pearson r=-0.376) and SR (P=0.035, Spearman’s rho=-0.362) of basal , mid and apical segments of RV. Conclusions Overall, in the assessment of RV function , echocardiographic measurement of strain a...
