The heart septal defect includes ventricular septal defect and atrial septal defect, and the onset of atrial septal defect is in the first place, which needs to be treated by surgery later on. The septal defect is a congenital heart disease, and if the surgery is performed in infancy, the quality of life of the child will not be affected and the prognosis is good. For children with obvious indications for non-surgical intervention, interventional therapy is used as early as possible. The incidence of ventricular septal defect is second only to that of atrial septal defect, and the treatment is likewise surgical and also non-surgical closure therapy can be chosen with obvious indications and contraindications. It is recommended to customize the treatment plan at the early stage of diagnosis of the disease and to choose the treatment method suitable for your condition.
