Tetralogy of Fallot


Tetralogy of Fallot

Tetralogy of Fallot

This refers to a congenital heart complication involving 4 types of anatomical heart abnormalities. However, only three of these conditions are common. In fact, TOF stands out as the most common cyanotic heart condition and the commonest cause of a condition known as blue baby syndrome.

Low levels of oxygenated blood is a resultant effect of the Tetralogy of Fallot and comes about due to the mixing of the deoxygenated and oxygenated blood found in the left ventricle through the VSD and due to the blocked aorta, the mixed blood in both the left and right ventricles flows via the pulmonary valve. This abnormal condition is referred to as right to left shunt.

Tetralogy of Fallot victim exhibits low levels of saturated oxygen in the blood that may or not contain cyanosis at birth or may also develop during the first year of life. In a situation where the baby may not be cyanotic, the condition is at times known as pink tet. Heart murmur is yet another symptom you will find in Tetralogy of Fallot patients and this ranges from faint to very noisy, feeding difficulties, weight gain failure, retarded physical development and growth, finger and toe clubbing, polycythemia and dyspnea on exersion.
