    Critical Congenital Heart Disease Screening Program


    Critical Congenital Heart Disease (CCHD) 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 can be detected using a simple and painless pulse oximetry test. The seven CCHD defects targeted by pulse oximetry screening are:

    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.
    The CCHD screening results are reported electronically to the State of Maryland for surveillance and quality assurance monitoring.
