Congenital heart disease is a common heart disease in children, with an incidence of about 0.8%. It is estimated that about 150,000 children with congenital heart disease are born in China every year, and because of the different types of pathology and conditions, the clinical manifestations are not consistent at different ages. Therefore, at present, 1. medical treatment is provided for complications such as heart failure, hypoxemia, cardiac arrhythmia and complications of infection. 2, interventional treatment The use of non-open-heart method instead of surgery, can be selected for some simple congenital heart disease radical surgery, some complex congenital heart disease staged surgery to replace part of the need for surgical interventional treatment of congenital heart disease, in order to achieve medical-surgical mosaic treatment and improve the effectiveness of surgery. 3.Surgical treatment is still the main mode of treatment for congenital heart disease, because surgery requires open-heart treatment, in addition, because of extracorporeal circulation and surgery itself brings some complications, therefore, we are currently committed to research in surgical techniques and strengthen the perioperative monitoring technology to reduce complications, in addition and medical congenital heart disease interventional treatment for mosaic treatment to achieve the best treatment mode.
