Abstract: Objective To explore the relationship between echogenic intracardiac focus (EIF) and fetal heart defects.Methods Retrospective study of fetuses with EIF were performed at our fetal cardiac service centers from August 2010 to October 2015.Fetuses were grouped by EIF locations (left ventricle,right ventricle and biventricle).The risk of heart defect in different groups were analyzed.Results A total of 2 204 fetuses were enrolled in our study.Of them,2 083 EIF were located in the left ventricle,while 83 were bilateral and 38 were right-sided.There were 98 of 2 083 fetuses(4.7％) with heart defects in left-sided group,1 of 83 fetuses (1.2％) in bilateral group,and 5 of 38 fetuses(13.2％) in right-sided group.Fetuses with right-sided EIF had significantly more heart defects compared with the other two groups(P ＜0.05).Conclusions A right-sided EIF may carry a higher risk of cardiac anomalies than a left-sided or bilateral EIF.Women carrying fetuses with right-sided EIF should be offered fetal echocardiography in the second trimester.
