Background: Congenital heart diseases represent major risk factor for infant morbidity and mortality. Accurate prenatal diagnosis may have clinical advantages for the development of the baby. Screening programs are meant to be used with the low-risk pregnant, thus they should be integrated into routine medical treatment. Objective: To evaluate the importance of ultrasound in assessing morphology and function of fetal heart. Methodology: A hospital based cross sectional study was conducted on 30 pregnant women who were randomly chosen and thought to have congenital cardiac problems. Aortic arch, bicaval, right and left ventricular outflow tracts, four chamber view, and three vessels view were all performed. E/A Ratio was used to evaluate the embryonic heart's functionality. Results: The most frequent congenital cardiac disorders, according to a routine echocardiogram, were ventricular septal defect and Tetralogy of Fallot, followed by atrioventricular septal defect. One case (6.6%) of hypoplastic left heart syndrome was discovered, along with other conditions such as aortic stenosis, cardiomegaly, atrial septal defect, single ventricle, and transposition of the major arteries. All cases had an E/A ratio less than 1, with the exception of those with an atrioventricular septal defect, a single ventricle, and hypoplastic left heart syndrome, where the E/A ratio was higher. Conclusion: Fetal heart screening must be incorporated into normal obstetric examination of cases not just for pregnant women who are at risk for congenital anomalies, but also for pregnant women without risk factors.
