Aim: To evaluate the fetal echocardiography findings in high risk mothers referred to Birmingham Women’s Hospital.

Method: A retrospective review of all fetal echocardiography performed over a 7 year period (01/01/1997 to 31/12/2003) were carried out.

Results: 3428 mothers were referred for fetal echocardiography and a total of 4816 echocardiograms were carried out during this period. The main reason for referrals were: a) previously affected child—27%; b) abnormal initial screening scan—20.6%; c) maternal cardiac condition—9.5%; and d) infant of diabetic mothers—8%. There were 606 reported abnormal echocardiograms (17.7%). The majority of the abnormalities were identified in mothers who had abnormal initial screening scan (61%). In addition, the fetal echocardiogram was also abnormal in 8.8% of cases with increased nuchal translucency and in 6% of infants of diabetic mothers. In those with previously affected child and maternal cardiac condition, the echocardiogram was abnormal in 2.5% and 2.8%, respectively.

Conclusion: Abnormal initial screening scans and increased nuchal translucency had the highest yield in identifying congenital heart disease. Infants of diabetic mothers also have an increased risk warranting fetal cardiac screening for congenital heart disease. Normal fetal echocardiogram provides reassurance to the remainder of parents.
