Abstract: In this paper, we discussed the application value of prenatal echocardiography in prenatal diagnosis of congenital heart disease. 3000 pregnant women within 20 to 24 weeks were selected as the observation group, on whom the fetal echocardiography and color Doppler ultrasonography were performed. Based on pregnancy outcomes, the sensitivity, specificity and accuracy of prenatal echocardiography and color Doppler ultrasound in the diagnosis of congenital heart disease were analyzed. We also compared the diagnostic value of different views in prenatal congenital heart disease. The results showed that the sensitivity, specificity and accuracy of prenatal echocardiography in the diagnosis of congenital heart disease were significantly higher than that of color Doppler ultrasound (P<0.05). The accuracy of four-chamber view of the fetal echocardiography for the prenatal diagnosis of fetal heart malformation was significantly higher than others (P<0.05). In summary, prenatal fetal echocardiography is of high value in prenatal diagnosis of congenital heart disease, which can significantly reduce the rate of missed diagnosis of congenital heart disease.

Key words: prenatal fetal echocardiography, congenital heart disease, prenatal diagnosis
