As we all know, there are two kinds of congenital heart disease treatment methods: surgery and interventional treatment. Surgical treatment is the main treatment modality, which is practical for all kinds of simple congenital heart diseases (such as: ventricular septal defect, atrial septal defect, arteriovenous insufficiency, etc.) and complex congenital heart diseases (such as: combined pulmonary hypertension, tetralogy of Fallot, transposition of the great arteries, complete pulmonary vein ectopic drainage, right ventricular double outlet and other heart diseases with cyanosis manifestation). Interventional therapy is a new treatment method developed in recent years, mainly for children with unclosed ductus arteriosus, atrial septal defect and partial ventricular septal defect that are not combined with other anomalies requiring surgical correction can be considered for interventional therapy. The difference between the two mainly lies in the fact that surgical treatment has a wider scope of application and can cure all kinds of simple and complex congenital heart diseases, but there is a certain degree of trauma, longer recovery time after surgery, a few patients may have arrhythmias, pleural effusion, pneumonia, low heart row and other complications, and also leave the surgical incision scars affecting the aesthetics. Interventional treatment is narrower in scope, less traumatic, with quicker postoperative recovery and no surgical scars. However, there are two types of interventions: medical interventions and surgical interventions. Interventional treatment has its limitations. Internal interventional treatment has radiation damage to the body and vascular damage, and is not suitable for large defects with existing right-to-left shunts, severe pulmonary hypertension, combined deformities requiring surgical correction, and poor margins because it must be done via a vascular route and is also limited by age. Surgical intervention, on the other hand, avoids radiation damage, and can be performed through both the transvascular route and the perforation of the chest, without age restriction. Through the above introduction, you may understand how to choose the treatment method for atrial defect of precordial disease. Simply put, surgical occlusion is the first choice, and for children over 3 years old, it is best to choose percutaneous surgical occlusion. Surgical occlusion of atrial defect via femoral vein under the guidance of esophageal ultrasound is already mature, with no incision, no bleeding, no radiation, no extracorporeal circulation and so on. It is the best treatment method for atrial defect at present. The incision is located in the right axilla, which is aesthetic and easy to heal, and is the preferred treatment for infants and children with atrial defects. If these two methods are not suitable, then small incision bloodless surgery can be chosen. In my opinion, the current treatment of atrial defect should be considered in this way.
