Congenital heart disease is a cardiovascular malformation caused by abnormal or impaired cardiovascular development during fetal life. The incidence of congenital cardiovascular disease in China is about 7 to 10 per 1,000, and hundreds of thousands of babies are born with congenital heart disease every year. The most common congenital heart diseases include ventricular septal defect, atrial septal defect, patent ductus arteriosus, pulmonary valve stenosis, tetralogy of Fallot, aortic stenosis and aortic constriction, and complex heart malformations such as right ventricular double outlet, single ventricle, ectopic pulmonary venous drainage, atrioventricular canal malformation, tricuspid atresia, transposition of the great arteries, etc. Congenital heart disease is easily detected early, and children often present with difficulty in feeding, palpitations after activity, shortness of breath, easy fatigue, cough, hemoptysis, and even fainting and right heart failure. Some children show purple head, face and body, low resistance, susceptible to disease and very easy to die early. Once a child is suspected of having congenital heart disease, he or she should go to the hospital in time, and through the doctor’s examination and auscultation of heart murmurs, and through the heart color ultrasound examination, most of them can be diagnosed, and early diagnosis and surgical treatment is the key to a healthy life. However, some of the surviving patients will lose the chance of surgery because of the increasing pulmonary artery pressure and right-to-left intracardiac shunt, which is already at an advanced stage. Most congenital heart disease can be completely cured through surgery, and there is almost no difference between a child and a normal person after radical surgery, which does not affect growth and development and future work, life and childbirth.
