Congenital Heart Defect Types
Skip to the navigation
There are many types of congenital heart defects . If the defect lowers the amount of oxygen in the body, it is called cyanotic. If the defect doesn't affect oxygen in the body, it is called acyanotic.
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.
Cyanotic heart defects include:
Congenital heart defects that don't normally interfere with the amount of oxygen or blood that reaches the tissues of the body are called acyanotic heart defects. A bluish tint of the skin isn't common in babies with acyanotic heart defects, although it may occur. If a bluish tint occurs, it often is during activities when the baby needs more oxygen, such as when crying and feeding.
Acyanotic congenital heart defects include:
A small hole in the heart, called a patent foramen ovale , is not considered a heart defect. It happens in many healthy people. But typically it doesn't need treatment.
