CCHD is a group of the most serious heart disorders present at birth. About 200 out of every 100,000 babies have CCHD. Children with CCHD are born with a wide range of problems with the heart’s structure. These problems prevent the heart from pumping blood normally to the lungs and the rest of the body. Because blood carries oxygen, parts of the body may not get enough oxygen. There are many types of CCHD, and all can cause serious health problems. These problems can worsen quickly and cause death in early childhood. Babies with CCHD need treatment early in life.
