Tetralogy of Fallot consists of four types of cardiac malformations: first, a ventricular septal defect; second, right ventricular outflow tract obstruction; third, an overriding aorta; and fourth, right ventricular hypertrophy. The main treatment for this condition is surgical repair. In recent years, there have been continual advancements in surgical procedures. Many children undergo a definitive one-stage surgery in early childhood, which can completely cure the condition. Thus, if the symptoms are mild, a definitive surgery can be performed in one stage. If the symptoms are more severe, a palliative shunt surgery may be performed first, followed by the definitive surgery when the general condition improves, and it can still be cured.
