Congenital heart defects are structural problems with the heart that are present from birth. These defects can affect any part of the heart, including the ventricles, valves, and great vessels. There are two major classifications of congenital heart defects: cyanotic and non-cyanotic.
The cyanotic type of congenital heart defect involves a problem with the heart’s ability to transport oxygenated blood throughout the body. This type of defect typically includes a hole in the wall between the left and right side of the heart, a defect in the valves, or an abnormality in the structure of the heart. These defects can cause oxygen-poor blood to be mixed with oxygen-rich blood, resulting in a bluish appearance in the skin and lips (cyanosis). Examples of cyanotic heart defects include tetralogy of Fallot, transposition of the great arteries, and tricuspid atresia.
Non-cyanotic congenital heart defects, on the other hand, do not involve an issue with oxygenated blood. These defects can include a hole in the heart, narrowing of the valves, or an abnormality in the structure of the heart. Examples of non-cyanotic heart defects include atrial septal defect, pulmonary valve stenosis, and coarctation of the aorta.
In both types of congenital heart defects, treatment may be necessary. Treatment options can include medications, surgery, and lifestyle changes. Depending on the severity of the defect, some individuals may require lifelong medical care.
