Patients with Tetralogy of Fallot who are treated with corrective surgery usually have a better prognosis and are less at risk, and patients are able to carry on with normal life and exercise, but strenuous exercise is not recommended. It is still dangerous after palliative surgery. Tetralogy of Fallot is a common congenital cardiovascular malformation that develops in infancy. Children are seen to have respiratory distress, cyanosis, and fainting in cases of severe oxygen deprivation. Tetralogy of Fallot requires radical surgical treatment, including tetralogy of Fallot correction and palliative surgery. The prognosis is usually better after corrective surgery, as patients can live and exercise normally with less risk of accidents. Palliative surgery, on the other hand, is used for patients who are temporarily unable to undergo corrective surgery, prioritizing the survival of the patient and requiring another corrective surgery at a later stage. The risk for patients after this type of surgery is still high, and daily attention should be paid to avoiding exertion and preventing infection. Patients with tetralogy of Fallot have a poor prognosis without surgery. Once the disease is diagnosed it should be treated aggressively with surgery, which can improve the prognosis and reduce the risk of the disease.
