Congenital Heart Defects occur when a baby’s heart or blood vessels do not form properly during the pregnancy. Heart defects are the most common birth defect. Most babies are born with normal hearts, but approximately 9/1,000 are found to have some form of heart defect. There are many types of heart defects ranging from mild to severe or critical. Approximately 25% of babies with heart defects have a critical condition. A critical congenital heart defect (CCHD) requires prompt diagnosis and treatment for the best outcome. Babies with undetected critical congenital heart defects are at risk for death or significant disability. |
