Generally, surgery is the main treatment, and interventional treatment is also feasible for some congenital heart diseases. 1.In principle, once congenital heart disease is detected, surgery should be performed as early as possible, but the younger the age, the greater the risk of surgery. Therefore, for simple atrial septal defect, ventricular septal defect, pulmonary artery stenosis, arteriovenous stenosis, etc., if there is no obvious pulmonary hypertension, the best time for surgery is between 3 and 6 years old. During this period, the child can be fully vaccinated, go to kindergarten and play as normal children. 2, some congenital heart disease must be operated early, otherwise the child will die prematurely, such as large ventricular septal defect, arteriovenous insufficiency, due to a large number of left to right shunt, repeated pulmonary infections in infancy with heart failure, simple drug therapy is difficult to control, often accompanied by severe pulmonary hypertension, so the operation should be completed early, generally within 1 year old, or even less than half a year old. 3. The best age for surgery in tetralogy of Fallot is over 2 years old, but if hypoxic attacks occur, early surgery is necessary. Children with complete endocardial cushion defects and complete abnormal pulmonary vein connections are often more severely ill and require early surgery. Interventional occlusion therapy is generally suitable for children over 3 years of age, with central atrial septal defect, patent ductus arteriosus and ventricular septal defect of the muscle being the best indications.
