Critical Congenital Heart Disease Screening Program
Critical Congenital Heart Disease is defined as a heart defect that is present at birth and can cause serious illness or even death if not detected in the first few weeks of life. Unfortunately, not all CCHD can be detected at birth but some types of CCHD can be detected most of the time using a simple and painless pulse oximetry test. The seven CCHD defects targeted by pulse oximetry screening are:

Hypoplastic Left Heart Syndrome
Tetralogy of Fallot
Total Anomalous Pulmonary Venous Return
Transposition of The Great Arteries
It is important to remember that Pulse Oximetry Screening may not detect these defects 100% of the time and it may also pick up other heart defects or illnesses in the infant.
If a baby does not “pass” the pulse oximetry screening, further evaluation is needed right away to see if the baby does have a CCHD. This evaluation should be done before the baby leaves the hospital! 1 in 100 babies are born with a congenital heart defect.
