FETAL ECHOCARDIOGRAPHY AS A ROUTINE ANTENATAL SCREENING TOOL FOR DETECTION OF FETAL CONGENITAL CARDIAC STRUCTURAL ANOMALIES.

Background: Fetal echocardiography plays a pivotal role in detecting congenital cardiac structural anomalies. Though foetal echocardiography is mostly reserved for high risk pregnant women, its role as a routine prenatal screening tool needs to be dened. To evaluate the role of fetal echocardiography as a routine Objectives: antenatal screening tool for detection of congenital cardiac structural anomalies.To compare the prevalence of congenital cardiac structural anomalies by fetal echocardiography in antenatal women with low risk and high risk factors for cardiac structural anomalies. The study was carried out in the department of radiodiagnosis, SNMC, Agra. Materials and methods: 500 fetal hearts between 18-26 weeks gestation were evaluated through fetal echocardiography.They were categorised into two groups -low risk (Group I) and high risk (Group II) and scanned through four chamber , LVOT , RVOT and three vessel view. Result: The prevalence of fetal congenital cardiac structural anomalies in this study is 14/1000.Fetal echocardiography had a sensitivity of 85% & specicity of 99%. PPV is 85% and NPV is 99%. The incidence of congenital cardiac structural anomalies in high risk and low risk group was 12 % & 14.8 % per 1,000 respectively. based on these ndings it is highly Conclusion: suggestive that every pregnant woman should be subjected to a detailed fetal echocardiography. Fetal echocardiography should be included as a part of routine antenatal screening irrespective of risk factors for congenital cardiac structural anomalies.
