Utility of Screening Fetal Echocardiograms Following Normal Level II Ultrasounds in Fetuses with Siblings with Congenital Heart Disease

Critical CHD was not missed with a normal LII-US in this at-risk population. F-echo also missed the majority of CHD when a LII-US was read as normal. The cost/benefit of screening F-echo in fetuses with siblings with CHD should be evaluated if a normal LII-US has been performed. Larger studies are needed to determine if these findings remain consistent.
