Congenital heart disease is the most common congenital abnormality, and simple congenital heart disease accounts for more than 80% of the total. The main types are: atrial septal defect ASD, ventricular septal defect VSD, patent ductus arteriosus PDA, pulmonary valve stenosis PS, etc. For the treatment of congenital heart disease, the consideration of age factor is one side, but more importantly, it is considered according to the comprehensive factors such as the type of lesion, the development of the disease and the impact on the developmental status of the child. In this issue of congenital heart disease treatment, it is important to follow the advice of a specialist cardiovascular surgeon. At present, there are three main clinical treatments for simple congenital heart disease: ● Surgical open-heart surgery: the main treatment means, with mature methods and exact results. Traditional surgical open-heart surgery is the main treatment modality with mature methods and definite results. It is generally applicable to all simple congenital heart disease and complex congenital heart disease (e.g. congenital heart disease with combined pulmonary hypertension, tetralogy of Fallot and other heart diseases with cyanosis). Compared with other surgical methods, open-heart surgery is less expensive and the hospital stay is about 7-10 days, but the surgery is more traumatic than other methods and the postoperative recovery is slower. Interventional occlusion: Less trauma, fewer complications, no surgical scars, and strict indications. Interventional occlusion is a new type of minimally invasive treatment developed in the past 10 years. It relies on complete equipment, advanced catheterization intervention rooms, and skilled cardiac surgeons or cardiology and pediatric specialists, and is mainly suitable for children with unclosed arterial ducts, atrial septal defects and partial ventricular septal defects that are not combined with other malformations requiring surgical correction. Interventional occlusion treatment has fewer complications, less trauma, no open-heart surgery, faster recovery, less pain for the patient, and a hospital stay of about 3 days, but it has stricter indications and higher costs compared to surgical procedures. Of course, as medical technology becomes more mature, the indications for interventional occlusion will be further expanded. Minimally invasive surgical occlusion: a combination of surgery and intervention. Minimally invasive surgical occlusion is also a new technique that has emerged in recent years. Instead of opening the chest, a small 2-3 cm incision is made in the right anterior sternum, a delivery system is placed, and under the guidance of cardiac ultrasound, the occluder is released to occlude the defect. The average operation time is less than 1 hour, and the patient is able to go down on the same day of the operation with a hospital stay of 3-4 days. It is indicated for patients with partial atrial septal defect, ventricular septal defect and patent ductus arteriosus. The respective characteristics of surgical open-heart surgery, interventional blocking surgery and surgical minimally invasive blocking surgery for congenital heart disease in infants are as above, which can be flexibly applied in the treatment of congenital heart disease according to the specific situation. The timing of surgery After the diagnosis of congenital heart disease, some parents think that their children are too young to withstand the trauma of surgery, and it is safer to wait until the children are older to perform surgery, thus delaying the disease and losing the opportunity of surgery, resulting in lifelong regret. With the development of modern medical technology, the operation time of heart disease can not be determined by the size of the age, but should be based on the specific condition of the patient, especially some complex congenital heart disease, for these children life and treatment time is calculated in “hours”, such as complete transposition of the great arteries, must be operated after birth, otherwise the child will Otherwise, the child will die suddenly or lose the opportunity for corrective surgery. In addition to complex congenital heart disease such as complete transposition of the great arteries, some children’s lives are measured in months, such as those with large ventricular septal defects, if surgery is not performed in time, the child’s development will be affected by recurrent heart failure and lung infections, and severe pulmonary hypertension will occur, and the opportunity for surgery will be lost. In addition, in children with tetralogy of Fallot, severe hypoxia can affect the function of the child’s vital organs, and even a single severe hypoxic episode can endanger the child’s life, and only about 10% of them can grow up to be healthy above the age of 10. In addition, some diseases affect children in terms of “years”, such as ventricular septal defect and atrial septal defect with a diameter of 0.5 cm or less, which have a small impact on the growth and development of children and can be observed regularly and treated by surgery at a later date according to the growth and development of the child and the disease. For whether to operate and the timing of surgery, it is important to visit the cardiovascular surgery department and listen to the specialist’s opinion so as not to miss the opportunity of surgery.
