Atrial septal defect is a type of congenital heart disease, which is not a primary orifice defect or a secondary orifice defect, but a secondary orifice defect is usually a defect around the foramen ovale. There are two types of treatment for secondary foramen ovale septal defect: first, interventional blocking surgery, which costs about 20-30,000 RMB; second, open-chest direct vision repair of atrial septal defect, which costs between 30-40,000 RMB. Both surgical procedures can achieve a radical cure, and cardiotonic, diuretic, anticoagulant and anti-inflammatory drugs are required after the surgery to enable the patient to recover as soon as possible.
