Tetralogy of Fallot

Tetralogy of Fallot (teh-TRAL-uh-jee of fuh-LOW) is a rare heart condition that is present at birth. That means it’s a congenital heart defect. A baby born with the condition has four different heart problems.

These heart problems affect the structure of the heart. The condition causes altered blood flow through the heart and to the rest of the body. Babies with tetralogy of Fallot often have blue or gray skin color due to low oxygen levels.

Tetralogy of Fallot is usually diagnosed during pregnancy or soon after a baby is born. If the heart changes and symptoms are mild, tetralogy of Fallot may not be noticed or diagnosed until adulthood.

People who are diagnosed with tetralogy of Fallot need surgery to fix the heart. They will need regular health checkups for life. [Source]
