Tetralogy of Fallot (Congenital Heart Disease): Symptoms & Treatment

Tetralogy of Fallot (TOF) is a congenital defect that hampers the normal flow of blood through the heart. This disease generally occurs in a baby whose heart does not develop properly while still in the womb. The defects generally affect the structure of the heart so much that they begin to cause oxygen-poor blood flow to the parts of the body. Infants who are suffering from tetralogy of Fallot have a tinge of blue in their skin colour and have an absolute restriction of blood flow from the right ventricle.

The condition, tetralogy of Fallot is also known to be associated with chromosomal abnormalities. When the flow of blood towards the lungs is limited, the fusion of the ventricular septal defect and aortic paves way for the passage of oxygen-poor blood coming back to the right atrium and the right ventricle.
