How are congenital heart defects grouped together?
Congenital heart defects are either cyanotic or acyanotic. Cyanotic heart defects Cyanotic heart defects are defects that allow oxygen-rich blood and oxygen-poor blood to mix. In cyanotic heart defects, less oxygen-rich blood reaches the tissues of the body. This results in the development of a bluish tint—cyanosis—to the skin, lips, and nail beds.
