Key result
Fetal echocardiography detects abnormal cardiac findings in ~15% of referrals, highest after abnormal ultrasound.
Why the study?
Fetal echocardiography is helpful in early detection of congenital heart disease, but the most common referral indications and outcomes in a tertiary-care setting were not well characterized.
Cross-Sectional (n=251)
No
Fetal echocardiography yields the highest rate of abnormal cardiac findings when performed for abnormal prenatal ultrasonography findings, highlighting its importance in high-risk pregnancies.
Maternal indications drove most referrals but abnormal ultrasound yielded highest detection rate; leaves open generalizability and screening impact.
Background and Aims: Fetal echocardiography is helpful in early detection of Congenital Heart Disease. Our study was conducted to evaluate the most common indications of referral and outcome in a tertiary-care fetal echocardiography practice.Methods: A Cross-sectional analysis of all pregnant women referred by obstetricians to cardiology unit for fetal echocardiography over a 1-year period (July 2014 and July 2015) was performed. The primary indications for referral for fetal echocardiography were obtained from the obstetric referral forms. Outcome data were extracted from performa containing client’s demographic, physical examination and the fetal echocardiograhic data. Postnatal Echocardiography was advised to all cases having positive echocardiographic finding.Results: A series of 251 fetal cardiac studies were reviewed. Average gestational age was 25.6 weeks (range, 18 to 38 weeks). Thirty-eight (15.1%) pregnant women had abnormal fetal cardiac findings. The most common referral for fetal cardiac scan was related to maternal indications (48.6%). Other indications were abnormal prenatal fetal findings in ultrasonography (23.1%), family history of CHD (12%), general screening (15.5%), and follow up of IVF (In-vitro fertilization) (0.8%). The highest yield of significant abnormal findings was there among patients referred with abnormal prenatal fetal finding in ultrasonography (47%).Conclusion: Majority of referral were for abnormal prenatal ultrasonographic findings. So, fetal Echocardiography is an important part of overall management of the pregnancy at risk for producing an infant with congenital heart disease.Nepalese Heart Journal 2016; 13(1): 9-12

Regmi et al. (2016) conducted a cross-sectional in Congenital Heart Disease (fetal screening) (n=251). Fetal echocardiography referral indications was evaluated on Abnormal fetal cardiac findings. Among 251 pregnant women referred for fetal echocardiography, 15.1% had abnormal fetal cardiac findings, with the highest yield (47%) in those referred for abnormal prenatal ultrasonography.
