TRANSPOSITION OF THE GREAT ARTERIES

 

1. What is it?
In normals, one artery takes blood from the right side of the heart to the lungs for oxygen. A second artery takes oxygen-rich blood from the left side of the heart to the body. In transposition, these two major arteries are reversed, so that oxygen-poor blood goes to the body and oxygen-rich blood goes to the lungs.

2. Why did it happen?
Cause usually unknown. Generally not inherited from parents and definitely not fault of parents.

3. What does it do to the heart?
Blood from the right side of the heart that should go to the lungs to pick up oxygen goes instead to the body. Heart must work harder.

4. How does it affect the child?
It causes blueness due to the lack of oxygen. It can also cause shortness of breath, and the child can tire easily.

5. Can it be fixed?
Yes. Operation usually required in infancy.

6. What can the child do ?
Before repair, child will usually determine own level of activity. After repair, should be able to play and work normally.

7. What should the parents do?
Follow doctor's advice on:
(1) giving medicines
(2) return visits to doctor
(3) special tests
(4) extreme care with dental procedures. Tell the dentist about the problem BEFORE he fixes child's teeth to avoid infection in the heart

This information is general. Only your doctor can give you precise details and instructions.
