Congenital Heart Defects:
Transposition of the Great Arteries



Transposition of the Great Arteries is a problem with the hallways coming out of the heart.

In a normal heart the Aortic hallway originates from the Left Ventricle and carries pink blood (with oxygen) from the Left Ventricle to the body. When this defect is present the Aortic hallway originates from Right Ventricle and therefore carries blue blood (no oxygen) to the body.


In a normal heart the Pulmonary hallway originates from the Right Ventricle and carries blue blood back to the heart to receive oxygen. When this defect is present the Pulmonary hallway originates from the Left Ventricle and carries blood full of oxygen back to the lungs. This is a waste of time and resources because that blood does not need to be getting more oxygen.
   

Symptoms:
A baby born with this defect would be born deeply blue and needs immediate attention because his body is receiving mainly blue blood, or not-oxygenated blood.
