How to treat a child with congenital heart disease, first of all, we should pay attention to general treatment, which is mainly to pay attention to rest and reduce activities to avoid increasing the load on the heart. In addition, the child can be given appropriate oxygen, etc., to relieve the symptoms of oxygen deprivation. In addition, if a child with congenital heart disease has other problems, such as heart failure or pulmonary hypertension, medications can be used to relieve the symptoms, help improve the performance and prolong survival. Because congenital heart disease is a heart malformation, surgery is required, but the timing of surgery needs to be determined in the context of the child’s presentation, including age and type of congenital heart disease. Surgery can be done by open-heart method, or for simpler congenital heart disease, interventional treatment can be used, which will cause less damage. In general, congenital heart disease needs to be treated in a comprehensive way. Before surgery, general treatment or medication is needed to relieve the child’s symptoms, and then the appropriate time for surgery is chosen according to the child’s performance and tolerance.
