Conclusion:
In conclusion, our study is the largest study to date to compare a multiparameter echo-Doppler assessment of RV systolic function with RVEF determined by cardiac MR for validation. Our results suggest the superiority of lateral RV free wall strain to other conventional echocardiographic parameters for detecting RV systolic dysfunction. Lateral RV free wall strain of <23.5% accurately detects moderately reduced RVEF and lateral RV free wall strain <20.5 % accurately detects severely reduced RV systolic function.
