Abstract

Objective: To elucidate the feasibility of tricuspid annular plane systolic excursion(TAPSE) and Tei index of right ventricle(RV) to evaluate right heart function of Ebstein anomaly(EA) patients before and after operation. Methods: Forty EA patients and twenty healthy controls underwent echocardiography(UCG) for evaluation of right heart function. EA patients underwent UCG before operation,one week and three months after operation, respectively. TAPSE was measured, Tei index of RV was calculatedin four-chamber view by tissue Doppler. Results: The study result showed that the echocardiographic parameters of RV systolic function including TAPSE, RVFAC, were decreased before the operation. However, the RV Tei index which reflected both the systolic and diastolic function of RV was increased before the operation. TAPSE improved significantly both on 1 week and 3 months after the operation(P<0.01). TAPSE was correlated with RVFAC. RVFAC is not suitable for postoperative comparison with preoperative use in the assessment of RV function before and after tricuspid regurgitation correction surgery. It is only suitable for comparison between different stages after operation. Conclusion: TAPSE and RVTei index assess the preoperative and postoperative patient’s RV function. The role of the tricuspid valve repair on improving the right heart function was also confirmed, and more experience could be accumulated on evaluation of right heart function.
