Congenital heart disease is due to cardiac vessels in fetal heart vascular dysplasia and malformations, is the most common pediatric heart disease. At present, the treatment of children with congenital heart disease were divided into surgical and medical treatment, the curative treatment of children with congenital heart disease is surgery, adjuvant treatment for medical treatment, medical treatment of congenital heart disease in children the main purpose is to relieve symptoms in children, the basis for surgical treatment of congenital heart disease in children treatment.

The most common surgical treatment for congenital heart disease in children is as follows:

1 ventricular septal defect (VSD): easy to produce pulmonary hypertension, pulmonary infection, especially 5mm or more defects, usually around 6-24 months of surgical treatment, once had pneumonia heart failure, should strive for early surgery.

2 patent ductus arteriosus (PDA): fetal blood by artery catheter is the main channel of pulmonary to aorta, pulmonary resistance decreased, born after breathing oxygen increase catheter, smooth muscle contraction, resulting in physiological closed catheter. This term appeared closed in 10 hours after birth, 48 hours and 96% closed. Anatomic closure within 2 year and 3 months. The vast majority closed within 6 months. If the catheter remains open at the age of 1, the operation should be closed. It is necessary to carry out the treatment of congenital heart disease in children, and the commonly used surgical procedures are interventional occlusion, arterial ligation and so on.

3 atrial septal defect (ASD): a small fraction of such pediatric congenital heart disease can be closed at the age of 1. If more than 5mm, and a heart enlargement, increased blood flow, it should be carried out surgery for congenital heart disease in children. At this time, the treatment of congenital heart disease in children is mainly in the operation of the operation. Atrial septal defect can be divided into small, medium and large defects. Children whose defect is less than 0.5cm for small, 0.5 ~ 1.0cm for medium-sized, 1.0cm above is large. Large atrial septal defect symptoms are very serious, can appear heart failure, pneumonia and other serious symptoms, should pay close attention to early congenital heart disease treatment.

It is generally believed that children with atrial deficiency less than 5mm can not be treated for congenital heart disease in children. But the need for regular color Doppler ultrasound review. Atrial septal defect should be treated from 2 to 3 years old. Large atrial septal defect defect due to severe symptoms, great harm to the child, if the treatment of children with congenital heart disease delays can be life-threatening, so doctors should listen to the heart, early treatment of children with congenital heart disease, such as heart failure, pneumonia and other serious symptoms, surgery can be performed in half a year old.

4 tetralogy of Fallot (TOF): included ventricular septal defect, pulmonary artery stenosis and right ventricular hypertrophy and aortic saddle deformity four. Tetralogy of Fallot without surgery prognosis is poor, about 50% of the children may die within 3 years. Children in more than 6-12 months of surgery, such as surgery in a timely manner, such children congenital heart disease treatment effect is better. In severe cases, the operation time should be ahead of schedule. The clinical symptoms are mild, can wait until 2-3 after radical operation, then the operation because of high success rate, low mortality rate. Most of the children can be treated with radical operation, four deformities at once.
