BACKGROUND: Fetal echocardiography is a complete two-dimensional and Doppler ultrasound evaluation of the human fetal cardiovascular system. It is completely noninvasive, harmless, and also serves as the fetal electrocardiogram.
AIM: To analyze the fetal echocardiographic cases referred to a tertiary cardiac center.
MATERIALS, METHODS, AND RESULTS: A total of 478 cases of fetal echocardiograms performed over a period of 5.5 years were compiled and analyzed. Details regarding gestational age, maternal, family history, exposure to teratogens, and reason for referral were recorded. The average gestational age at referral was 24.8 ± 4.6 weeks and maternal age was 24.7 ± 4.3 years. Indications for referrals were abnormal fetal cardiac scan in 128 (26.8 %), previous sibling with congenital heart disease (CHD) in 99 (20.7 %), maternal indications in 87 (18.2 %), echogenic intracardiac focus (EIF) in 87 (18.2 %), high risk in 50 (10.5 %), rhythm problems in 21 (4.4 %), and others (extracardiac malformations) in 6 (1.2 %). In the 87 CHD cases diagnosed, nearly 70 % had complex CHD and 66.7 % were referred only after 22 weeks of gestation. A further 103 cases had EIF, 17 cases had fetal arrhythmia, 3 cases had cardiac masses, and the remaining 268 cases had normal fetal echocardiograms.
CONCLUSION: Fetal echocardiography can effectively identify abnormal hearts and has enhanced prenatal detection of CHD. The concern in the Indian scenario is the late referrals, lack of follow-up, and financial difficulties, all of which conspire against the chance of the fetus with heart disease getting appropriate treatment.
