9. Assessment of right ventricular ejection fraction by 3D echocardiography in patients with pulmonary hypertension
Main Article Content
Abstract
Pulmonary hypertension is a serious disease, which causes right ventricular failure - a main factor leading to death. This study was conducted to evaluate the right ventricular ejection fraction by 3D echocardiography and describe the correlation with some indicators of right ventricular systolic function on 2D echocardiography. The results showed that the average right ventricular ejection fraction on 3D ultrasound in patients with pulmonary hypertension was 40.1 ± 10.6%. Right ventricular ejection fraction is lower in primary pulmonary hypertension compared with secondary pulmonary hypertension. The detection rate of right ventricular systolic dysfunction on ultrasound was highest when assessed by right ventricular ejection fraction (3D RVEF) with 63.6%. 3D RVEF correlates very closely with fractional area change (FAC) (r = 0.7587), closely correlated with TAPSE (r = 0.6834). Conclusion: The 3D echocardiography method assists to increase the diagnostic value and accurately assess the right ventricular systolic function in patients with pulmonary hypertension.
