High risk factors of fetal congenital heart disease and the significance of prenatal ultrasound screening

HUANG Shi-hua;The First People′s Hospital of Yongkang Department of Ultrasound;  
Objective:To study the high risk factors of fetal congenital heart disease(CHD)and the significance of prenatal ultrasound screening,and provide a theoretical basis for prenatal and postnatal care. Methods:A total of 1640 single-pregnant pregnant women who participated in the ultrasound examination in pregnancy from January to May 20,2014 were enrolled in the study. Prenatal ultrasound screening was performed to compare prenatal ultrasound screening results and autopsy,after birth.Ultrasound system examination results,and retrospective analysis of its clinical data,using chi-square test and Logistic multifactor analysis to screen for high risk of prenatal fetal congenital heart disease factor. Results:In 1640 cases,prenatal ultrasound was diagnosed as congenital heart disease in 18 cases,the incidence rate was 1.10%,postpartum echocardiography confirmed 10 cases,postoperative induction of autopsy confirmed 7 cases,misdiagnosis in 1 case,the accuracy rate was 94.44%. Univariate and further Logicstics regression multivariate analysis showed that age≥35,family history of CHD,gestational hypertension,active or passive smoking history in pregnant women,and gestational diabetes in pregnant women were independent risk factors for CHD. Conclusion:Prenatal ultrasound is an effective method for screening fetal congenital heart disease. For pregnant women with high risk factors,early detection and intervention should be screened to achieve the goal of prenatal and postnatal care.
