Radical surgery for congenital heart disease without incision, i.e. interventional blocking treatment for congenital heart disease, has a high success rate, and children can get out of bed the day after surgery and be discharged from hospital within a week after surgery with satisfactory surgical results. Nanyang City took the lead in carrying out this technology, with mature technology and rich experience, and has relieved many children of their pain. Every year, 150,000 newborns in China suffer from congenital heart disease, of which the incidence of arteriovenous ductus arteriosus accounts for about 15%, the incidence of atrial and ventricular septal defects accounts for about 10-12%, as well as pulmonary valve stenosis, pulmonary arteriovenous fistula, coronary arteriovenous fistula and so on. In the past, surgery was the only treatment method, and although the success rate was high, surgery required open-heart surgery, which was traumatic and had a relatively long postoperative recovery time. With the continuous development of medical technology, level and medical devices, non-invasive, less invasive and minimally invasive interventional treatment of congenital heart disease has created a new field of congenital heart disease treatment. During the treatment, the doctor punctures the patient’s blood vessel (usually using the blood vessel at the root of the thigh) and delivers an appropriately sized blocker to the lesion to seal the defective or unclosed arterial duct through a specially designed sheath of 2-4 mm in diameter, under the guidance of X-ray and ultrasound, in order to achieve the treatment purpose. It is confirmed through clinical practice that interventional occlusion of precordial disease has the advantages of small trauma, short operation time (about 1 hour), quick recovery (can be out of bed the next day after operation), no special anesthesia and extracorporeal circulation, and short hospitalization period (about 1 week). General anesthesia is required only if the patient is too young to cooperate with the operation. The indications for this blocking procedure are very broad, and atrial septal defect, patent ductus arteriosus, and ventricular septal defect can all be treated by interventional methods. Interventional treatment of congenital heart disease is characterized by less trauma, less pain, higher success rate, lower mortality rate, shorter hospital stay and no scarring after the procedure, and the results are comparable to surgery for the purpose of radical treatment. At present, congenital heart diseases that can be treated by interventional methods include: 1, arteriovenous ductus arteriosus of any age, weight and shape; 2, two-hole central atrial septal defect less than 36 mm; 3, membranous and muscular ventricular septal defect; 4, simple pulmonary valve stenosis.
