Causes[edit | edit source]

The exact cause of Tetralogy of Fallot is unknown. However, it is believed to be caused by a combination of genetic and environmental factors. Some cases have been associated with DiGeorge syndrome, Down syndrome, and Alagille syndrome.

Symptoms[edit | edit source]

Symptoms of Tetralogy of Fallot include cyanosis (a bluish coloration of the skin due to low oxygen levels in the blood), shortness of breath, and fainting. These symptoms may vary in severity and may not be present at birth, but typically develop during the first year of life.
