There are four main surgical procedures that can be used for simple precordial disease, namely conventional open-heart, small axillary incision, interventional and thoracoscopic. Simple precordial diseases, such as ventricular septal defect, atrial septal defect, and patent ductus arteriosus, can be treated partially without surgical open-heart surgery. First of all, the safest of the four surgical procedures is conventional open-heart surgery, which is safe because of the good surgical field of view and the mature technology, although it causes a lot of damage. Some complex congenital heart diseases must be treated with open-heart surgery. Secondly, small axillary incision is a modified procedure of conventional open chest for congenital heart disease treatment, which can be used for some simple type of congenital heart disease. Once again, intervention is a minimally invasive treatment, mainly through the placement of blockers in blood vessels to treat simple congenital heart disease, which has the characteristics of small damage and safety. However, this surgical procedure must wait until the patient has a certain diameter of blood vessels, which generally requires more than 3 years of age. Recently, there is a development of blocking from the jugular vein, which can bring the age forward appropriately. Huge defects, closer to the valve and other conditions are not suitable for the blocking approach. In addition, thoracoscopy is a congenital heart disease treatment technique that has emerged in recent years. The treatment of simple congenital heart disease through thoracoscopy is less invasive, but the selection of patients is more stringent and the risks of the procedure are greater.
