From Wikipedia: Tetralogy of Fallot (TOF) is a congenital heart defect which is classically understood to involve four anatomical abnormalities (although only three of them are always present). It is the most common cyanotic heart defect, representing 55-70%, and the most common cause of blue baby syndrome..
In the neonatal period, most forms of congenital heart defects are associated with hypoxemia. This means that there is not sufficient oxygen in the arterial blood. However, this condition does not always lead to visible cyanosis in the first days of life, which is why it often goes unnoticed.bout one quarter of all newborn children with congenital heart disease suffer from critical congenital heart defects. They will require surgery or catheter interventions within their first year of life.
