Tetralogy of Fallot treatment in Hyderabad


These defects, which affect the structure of the heart, cause deoxygenated blood to flow from the heart to the rest of the body. Infants and children with Fallot tetralogy usually have blue-tinged skin because their blood does not have enough oxygen.

Fallot tetralogy is often diagnosed in infancy or shortly thereafter. However, depending on the severity of the abnormalities and symptoms, the Fallot tetralogy may not be recognized later in life in some adults.


The tetralogy of Fallot’s symptoms varies depending on the degree of obstruction to blood flow from the right ventricle to the lungs. Signs and symptoms can include:

The reasons

Fallot tetralogy occurs during fetal growth, when the baby’s heart is developing. Although factors such as poor maternal nutrition, viral diseases, or genetic disorders can increase the risk of this condition, in most cases the cause of the Fallot tetralogy is unknown.

The four anomalies that make up the Fallot tetralogy include:

Pulmonary valve stenosis. Pulmonary valve stenosis is a narrowing of the pulmonary valve – the valve that separates the lower right chamber of the heart (right ventricle) from the main blood vessel that leads to the lungs (pulmonary artery).

The narrowing (narrowing) of the pulmonary valve reduces the flow of blood to the lungs. The narrowing can also affect the muscle below the pulmonary valve. In some severe cases, the pulmonary valve does not form properly (pulmonary atresia) and leads to decreased blood flow to the lungs.

Risk factors

Although the exact cause of the Fallot tetralogy is unknown, several factors can increase the risk of having a baby born with the disease. These risk factors include:
