Overview of Congenital Heart Disease

Congenital heart defects occur during the crucial first eight weeks of a baby's development.

Fetal Circulation

Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta.

In up to 90 percent of cases of congenital heart defect, the cause is thought to be a combination of genetics and environment.

Down syndrome, DiGeorge syndrome, and Marfan syndrome are marked by birth defects that involve the heart, as well as other organs and tissues.
