  2. Normal HeartIn a normal heart, the blood circulates through the right ventricle and into the pulmonary artery, which then directs the blood to the lungs to get oxygen. After passing through the lungs, the blood re-enters the heart, goes through the left ventricle to the aorta, and then circulates through the body. This process is what makes the heart one of the most complicated and remarkable organs in the body. A Blue Baby HeartIn a Blue Baby heart, there are four defects that usually occur simultaneously as Tetralogy of Fallot (Blue Baby syndrome). They are: pulmonary stenosis, a narrowing at the opening of the pulmonary artery that constricts the flow of blood to the lungs. ventricular septal defect (VSD), a hole in the septum or wall between the ventricles that allows mixing of the blood between the two chambers which causes de-oxygenated blood to be sent into the body. right ventricular hypertrophy, an overdevelopment of the right ventricle as it works harder to overcome the handicaps of stenosis and VSD. an overriding aorta, which exacerbates the VSD, causing more mixing of blood between the ventricles. The victims of this condition, called "blue babies," are cyanotic, often tired and listless, and capable of only limited physical activity. Before 1944, there was no way to help victims of this malformation, and they rarely lived more than a few years.
