As the special structure of right ventricular,anaccurate measurement of right heart function has always been a problem.Ultrasound cardiogram(UCG) is the most convenient and effective method of assessment of the right heart morphology,blood flow and function.Three-dimensional ultrasonography has its own unique advantage on right ventricular volume and ejection fraction(EF).MRI and CT may be good choices to measure right ventricular volume and EF.Some biochemical markers may also play roles in assessment of right heart.

The right ventricular function is an independent prognostic indicator of morbidity and mortality in patients with right heart diseases such as right heart failure and pulmonary hypertension and so on,so exacting evaluation of the right ventricular function has becoming an inevitable clinic problem.The 3-dimensional echocardiography(3DE)leads to a better evaluation of the right heart function.The application progresses of 3DE for evaluation on right heart function were reviewed in this article.

Objective To evaluate the right ventricular function of congenital heart disease with left to right shunt by Tei index which were measured by tissue Doppler imaging.Methods 60 patients with CHD were divided into two groups,while 35 patients with pulmonary hypertension in group A and 25 patients with no pulmonary hypertension in group B.There were 33 healthy volunteers in healthy control group.RV Tei index was measured by tissue Doppler imaging to analyze the differences of the Tei indexes among all the three groups.Results The right ventricular Tei index in group A was significantly higher than those in the controls and group B(P0.05).The difference of Tei index between the group B and the controls was not significant(P0.05).There was better correlation between the Tei index and the pulmonary hypertension(P0.01).Conclusion The right ventricular function of CHD with left to right shunt and pulmonary hypertension decreases in various extent.The right ventricular Tei index measured by tissue Doppler imaging can be used to estimate the right ventricular global function comprehensively and exactly.

Objective: In patients with repaired tetralogy of Fallot, to assess the value of new parameters derived from nonconventional echocardiography in reflecting the right ventricular insufficiency status determined by N-terminal pro-B-type natriuretic peptide (NT-pro BNP).
