Prenatal Detection of Congenital Heart Disease: Importance of Fetal Echocardiography Following Normal Fetal Cardiac Screening.

Fetal echocardiography may be performed because of noncardiac indications (the pregnancy is identified as high risk for fetal cardiac disease), or because of fetal cardiac indications (abnormal fetal heart at the time of a screening ultrasound). Considering recent improvements in fetal cardiac screening over the past decade, the goal of this single institution study was to reconsider the importance of performing fetal echocardiography purely for screening (noncardiac) indications. We performed a retrospective analysis to review screening and fetal cardiac indications and fetal cardiac findings for fetal echocardiograms performed at UCLA between 2015 and 2019. Fetal heart disease was identified in 391 (15%) of 2592 pregnancies in this study. Among these 391 cases, 227 (58%) occurred in low-risk pregnancies (without screening indications). While 79% of the cases of fetal cardiac disease were referred with fetal cardiac indications, 21% of the cases were referred with exclusively screening indications. Fetal cardiac disease was discovered on fetal echocardiograms in 4% of pregnancies referred for exclusively screening indications, but the frequency of fetal cardiac disease following normal fetal cardiac screening has decreased from 6% in 2015 to 3% in 2019. In our population, we recommend continued referral for fetal echocardiography for pregnancies identified as high risk for CHD. However, as fetal cardiac screening continues to improve, referral for fetal echocardiography following normal fetal cardiac screening will have diminishing value and yield. © 2022.
