There are two types of treatment for congenital heart disease: surgical and interventional. Surgical treatment is the main treatment modality, which is useful for simple congenital heart disease (e.g., ventricular septal defect, atrial septal defect, arteriovenous ductus arteriosus, etc.) and complex congenital heart disease (e.g., congenital heart disease with pulmonary hypertension, tetralogy of Fallot and other heart diseases with cyanosis). 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. 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 postoperative recovery time, a few patients may have arrhythmias, chest and heart cavity effusion and other complications, and also leave surgical scars affecting the aesthetics. Interventional treatment is narrower in scope and more expensive, but non-invasive, with fast postoperative recovery and no surgical scars.
