Congenital heart disease includes PDA (patent ductus arteriosus) close to 100%, ASD (atrial septal defect) about 80%, VSD (ventricular septal defect), the overall prevalence of congenital heart disease worldwide is 5‰ ~ 12.5‰. China’s prevalence of precocious heart disease in 6.87 ‰ ~ 14.39 ‰, it is worth noting that in recent years, the incidence of precocious heart disease in China has risen rapidly, 4 times higher in 10 years, for 10 consecutive years to become the first birth defects in China. In Guangdong, there are about 10,000 children born with congenital heart disease every year, and the incidence rate is as high as 1%, which is the highest in the country. Interventional treatment of congenital heart disease has the following advantages compared with surgery: 1. No incision is needed on the back of the chest, only a needle eye (about 3mm) is left in the groin. Because of the small trauma and pain, it can heal in a few days after surgery without leaving scars; there is also no need to open the chest cavity, much less to cut open the heart. 2. The treatment does not require the implementation of systemic external circulation and deep low temperature anesthesia. The child only needs basic anesthesia without intubation to cooperate, and the older child only needs local anesthesia. In this way, the occurrence of extracorporeal circulation and anesthesia accidents can be avoided, and there will be no impact on the brain development of children. 3.Because of the low bleeding of interventional treatment, no blood transfusion is required, thus avoiding the possible adverse reactions caused by blood transfusion. 4.Compared with surgical procedures, interventional treatment has a shorter operation time, shorter hospital stay and faster postoperative recovery. Generally, you can start to drink in about 30 minutes to 1 hour, and you can get out of bed in 20 hours after the operation, and you can be discharged from hospital in 1~3 days. 5.At present, the success rate of various interventional treatments for children suitable for interventional treatment is over 98%, and the postoperative complications are less than those of surgical procedures. It is just like surgery and can have a radical effect.
