Overview
Pathophysiology
Tetralogy of Fallot results in low oxygenation of blood due to mixing of oxygenated and deoxygenated blood in the left ventricle through the VSD and preferential flow of both oxygenated and deoxygenated blood from the ventricles through the aorta because of obstruction to flow through the pulmonary valve. This is known as a right-to-left shunt.
Children with tetralogy of Fallot may develop acute severe cyanosis or hypoxic "tet spells". The precise mechanism of these episodes is in doubt, but presumably results from an increase in resistance to blood flow to the lungs with increased preferential flow of desaturated blood to the body.
