Application Value of Tei Index in Evaluating Fetal Left Ventricular Function in
Congenital Heart Disease
CHEN Yu-shu,JIANG Fan,TAN Jie,GU Li-li,LUO Ping,LIANG Jing,XU Xiao-wei (Department of Ultrasound,the Second Affiliated Hospital,Anhui Medical University,Hefei 230601,Anhui,China) Abstract：Objective To investigate the application value of Tei index in evaluating left ventricular function in congenital heart disease (CHD). Methods From June 2017 to October 2018, 44 cases of CHD fetus were diagnosed as fetal cases by fetal echocardiography. According to the ratio of cardiothoracic area, the cardiothoracic ratio was normal ( =29) and the ratio of cardiothoracic ratio was increased( =15); 60 cases of normal pregnancy with the same gestational age were selected as the normal control group. All fetal left ventricular short axis shortening rate (LVFS), left ventricular ejection fraction (LVEF), mitral valve E/A value, and left ventricular Tei index (LVTei) were observed using M-mode echocardiography and pulsed Doppler.Results The fetal LVEF in the case group was lower than that in the normal control group, and the LVTei was higher than that in the normal control group,the difference was statistically significant ( <0.05). There was no significant difference in the LVFS and E/A between the two groups ( > 0.05). In the case group, the central chest was higher than the normal fetus LVTei than the normal control group,the difference was statistically significant ( <0.05). There was no significant difference between the normal group and the normal control group LVEF, LVFS and E/A ( >0.05). In the case group, the chest height ratio of the fetus was higher than that of the normal and normal control group. The LVEF, LVFS and E/A were lower than those of the normal and normal control group,the difference was statistically significant ( <0.05).Conclusion The Tei index measurement method is simple and reproducible. It can be used as an index to evaluate the left ventricular function of CHD, provide a reliable basis for early assessment of the prognosis of children, and guide the treatment of perinatal period. Key words：Tei index;Congenital heart disease;Ratio of cardiothoracic area;Fetal heart function
