Congenital heart disease is an organic cardiac lesion that develops before the fetus is born. Common types include atrial septal defect, ventricular septal defect, atrial septal defect, pulmonary valve stenosis, and tetralogy of Fallot. According to epidemiological surveys, 7-8 out of every 1000 babies born in China suffer from congenital heart disease. It has been reported that with the development of cardiac ultrasound and other technologies, the detection of tiny ventricular septal defect and bilobed aortic valve, etc., the incidence of congenital heart disease can reach 75/1000. 150,000-170,000 new patients with congenital heart disease are added every year, of which about 120,000 patients need treatment, and congenital heart disease is is the first malformation at birth in China. At present, there are about 4 million patients with congenital heart disease in China, and there is a phenomenon of regional focus, with the incidence rate in backward areas being higher than that in developed areas and rural areas being higher than that in urban areas. The treatment methods of congenital heart disease mainly include surgery and interventional treatment. Surgery is mainly the treatment of cardiovascular malformations such as repair through open-heart with extracorporeal circulation support, which is still the main means of treatment for congenital heart disease. Interventional treatment mainly includes balloon dilatation, which is used for the treatment of congenital heart disease such as pulmonary stenosis and aortic stenosis; another major method of interventional treatment is the use of blockers to close abnormal channels in the heart vessels, which is mainly used for the treatment of precordial arteriovenous catheterization, atrial septal defect, ventricular septal defect, etc. In 2001, the FDA approved the use of Amplatz umbrella for the clinical treatment of atrial septal defect and other precardiac diseases, but the cost of imported materials is very high, and most of the domestic patients with precardiac diseases can hardly afford it. 2003, the successful development of domestic blocking umbrella has strongly promoted the development of interventional treatment for precardiac diseases in China. In 2003, the successful development of domestic blocking umbrellas gave a strong impetus to the development of interventional treatment for precocious heart disease in China. According to the data, there are about 50,000 cases of patients with precordial disease receiving surgery and about 15,000 to 20,000 patients receiving interventional treatment every year in China. The above figures show that the number of congenital heart disease patients who can receive treatment every year is a drop in the bucket for the huge number of congenital heart disease patients, and a large number of congenital heart disease patients cannot receive effective treatment because of various reasons. And for children with congenital heart disease waiting for months or years will lose the best time for treatment, and eventually develop into resistance pulmonary hypertension and heart failure, these situations are especially serious in rural and less developed areas. The Second Department of Cardiology of the Affiliated Hospital of Weifang Medical College carries out preferential treatment activities for congenital heart disease all year round, and will provide multiple preferences for patients with congenital heart disease who receive treatment in our hospital, and welcome patients with congenital heart disease can contact for consultation.
