Screening
There is an increase in the routine use of neonatal pulse-oximetry of all neonates for cyanotic heart disease. This has the potential to identify mildly cyanotic infants and should prompt further investigation of the neonate.[24] All children with certain syndromes such as trisomy 21 should be screened for congenital heart disease (CHD). A screening fetal echocardiogram may be indicated in a pregnant mother who has had other children with CHD or has CHD herself.
