Major Congenital Heart Disease (CHD) occurs in about 35/10,000 births.Despite advances in screening programme,up to 50% of major congenital heart diseases were still missed on fetal anomaly scans in UK.
To identify missed cases of major congenital heart disease1 which require immediate cardiac assessment and/or treatment within the first two weeks of a child’s life.
Babies born from 1st January 2014- 31st Dec 2018 who were diagnosed with CHD were identified from local neonatal database. Cases with confirmed post-natal echocardiogram CHD were included and cases identified antenatally were excluded. Isolated cases of ASD and VSD were also excluded from analysis.
48 babies with CHD were identified. 30 were missed on antenatal screening. Of them, 17 had major CHD needing surgical intervention. Out of 17, 11 had major cyanotic heart disease and 6 had major acyanotic heart disease.

Up to 35% of major congenital heart diseases were still missed on foetal anomaly scans in UK. This highlights importance of implementing newborn pulse oximetry screening in conjunction with Foetal Cardiac Screening Protocol to improve detection of major CHD.
