Surgery is the mainstay of therapy for tricuspid atresia. In the first 8 weeks of life if there are severe Cyanosis and pulmonary obstruction and normal positioning aorta and pulmonary artery, making a shunt between systemic subclavian artery to the pulmonary artery is necessary which is called Blalock -Taussig (BT shunt). If the pulmonary artery comes from the left ventricle and is overflowed, pulmonary artery banding is useful for lowering the pulmonary blood flow. In older children, bi-direction Glenn shunt which is the connection between superior vena cava to the pulmonary artery is planned for transferring the blood to the pulmonary system. Fontan procedure is a conduit between the inferior vena cava and the pulmonary artery whether transfers the systemic venous blood to [[pulmonary circulation at the age of 2-3 years old.
