What are the main symptoms of tetralogy of Fallot?

Tetralogy of Fallot is a kind of congenital heart disease, which is a common cardiac developmental malformation. There are mainly four kinds of cardiac structural malformations: right ventricular hypertrophy, ventricular septal defect, aortic straddling, right ventricular outflow tract obstruction (pulmonary artery stenosis), so it is called tetralogy of Fallot. Children with this disease will have blue lips, nails and skin when they are sucking, crying, emotional and cold,

The severity of the disease mainly depends on the degree of right ventricular outflow tract obstruction. In the case of no treatment, children generally die in early childhood, few patients can live to 30 years old. After surgical correction, most of the children can live a normal life.

Crouching is a characteristic posture in children with tetralogy of Fallot. When walking and playing, they often squat for a while. When squatting, the lower limb flexes, which reduces the amount of venous blood and reduces the cardiac load. At the same time, the lower limb arteries are compressed, which increases the resistance of systemic circulation, and reduces the right to left shunt, thus temporarily alleviating the symptoms of hypoxia. Can't walk small baby, often like adults hold up, lower limbs flexion.
