Tetralogy of Fallot is a combination of four heart defects that are present at birth (congenital). The condition develops in an unborn baby early in pregnancy, while the heart is developing. Together, these defects cause problems in blood flow, which makes it difficult for the body to get enough oxygen-rich blood.
Tetralogy of Fallot is usually discovered within the first year of life when a health care provider hears an abnormal sound (heart murmur) when listening to the heart beat.
The cause of this condition is not known. In some cases, it may be caused by genes that are passed from parent to child (inherited).
When these symptoms occur suddenly, it is called a tetralogy spell. Tetralogy spells occur when there is a sudden drop in blood oxygen levels.
Your child may see a heart specialist (cardiologist) to manage this condition.
