At present, there are two main methods of treatment for congenital heart disease: surgical treatment and medical interventional treatment. 1.Surgery: including the following two methods: 1. Open-heart surgery: it is the main treatment mode, with a wide range of application, and can cure all kinds of simple and complex congenital heart disease, but generally requires extracorporeal circulation and general anesthesia, which requires incision of the sternum and heart, which is traumatic to the body, and generally requires blood transfusion during the operation, and has a long recovery time after the operation, and a few patients may have arrhythmia, chest and heart cavity effusion and other complications. Complications, and also leave surgical scars affecting the beauty. Minimally invasive blocking: a surgical method emerging in recent years, the chest wall and heart are cut open and the blocker is placed under ultrasound monitoring, the operation time is short, no blood transfusion is needed, the recovery is fast, but the chest wall still leaves scars. Interventional treatment Interventional treatment is one of the most advanced methods in the world for treating congenital heart disease. During the treatment, the doctor punctures the patient’s blood vessel (usually the right thigh femoral vein or/and femoral artery) with a small special needle and delivers a suitable-sized blocker to the lesion to block the defective or unclosed ductus arteriosus under the guidance of DSA, or dilates the narrowed valve with a suitable-sized balloon. It is mainly used for simple heart diseases such as ventricular septal defect, atrial septal defect (secondary foramen ovale), arteriovenous stenosis, pulmonary stenosis, aortic stenosis, etc. The operation time is short, usually half an hour to one hour, and does not require extracorporeal circulation, and can be performed in school-age children and adults under local anesthesia. No scar will be left after the operation. Interventional treatment has the same scope of application as minimally invasive blocking, but is superior to the latter because it is less invasive and does not leave any scars. Interventional treatment should be considered as a priority in children with other cardiac anomalies that do not require surgical correction.
