Congenital Heart Defects in Newborns

newbornCongenital heart defects (CHDs) are abnormalities present at birth that can affect the structure and function of the heart. Approximately 1% of infants born in the United States have CHDs. A baby’s heart begins to develop at conception, but is completely formed by eight weeks into the pregnancy. CHDs occur during this crucial first eight weeks of the baby’s development. Specific steps must take place in order for the heart to form correctly. Often, CHDs are a result of one of these crucial steps not happening at the right time, leaving a hole where a dividing wall should have formed or a single blood vessel where two ought to be, for example.

Some CHDs are known to be associated with genetic disorders, such as Down syndrome, but the cause of most CHDs is unknown. In these cases, doctors generally assume the cause is some mixture of environmental and inherited (genetic) factors.

Common types of congenital heart defects, which can affect any part of the heart or its surrounding structures, include:

While CHDs sometimes go undiagnosed for years — even into adulthood — others cause serious symptoms at birth, requiring the infant to be placed in the hospital’s neonatal intensive care unit (NICU) for immediate evaluation by a cardiologist.

Today there are more treatment options for CHDs than ever before, and most defects are treated successfully. If you suspect that your child has a heart defect, the sooner you get medical attention, the better chance your child will have of making the fullest recovery possible.
