Due to the lack of professional access system and related technical specifications, the mortality rate of pediatric congenital heart disease patients treated in non-specialized hospitals is more than 10 times higher compared with that in cardiac specialized hospitals. There are 3 main reasons why the mortality rate of pediatric congenital heart disease is so disparate in different hospitals: 1. There are many children with congenital heart disease and few professional doctors: about 150,000 children with congenital heart disease are born in China every year, accounting for 7% of live births. The incidence of congenital heart disease ranks first among all kinds of birth defects, and the number of sick children who have not received surgery is as many as 1.5 million. The number of pediatric congenital heart disease interventional doctors is only a few who have received professional training, and their treatment capacity is far from meeting the demand.2. Many general hospitals also carry out surgical treatment of pediatric congenital heart disease: as a population that keeps growing, pediatric cardiac surgery skills, extracorporeal circulation characteristics, anesthesia support, postoperative monitoring, etc. are very different from those of adults, but all hospitals that carry out adult cardiothoracic surgery have a great deal of interest in However, all hospitals that perform adult cardiothoracic surgery are “all-inclusive” to small patients, resulting in a great difference in the mortality rate of pediatric congenital heart disease surgery in different hospitals. The problem is that there are many children who are not operated properly and are transferred to cardiothoracic hospitals for another operation after surgery.3. Confusion in the choice of treatment methods: The treatment of pediatric congenital heart disease can be based on the condition of interventional therapy, surgical treatment and other methods. However, there is no unified standard for choosing which treatment plan is more suitable for either cardiothoracic surgery or cardiology, so many hospitals choose the method not according to the needs of the child’s condition, but according to the hospital’s own conditions. In other words, hospitals with good surgical conditions choose open surgery, interventional conditions choose interventional treatment, the result is to cause damage to the child, resulting in many avoidable complications or even the death of the child.
