The cost of atrial septal defect surgery is determined on a case-by-case basis. If the child is able to go through a minimally invasive interventional method, the cost of the surgery is relatively low, and the cost varies depending on the instruments and equipment used for the intervention. The general cost of interventional surgery is about 30,000-40,000 RMB; if the septal defect is not suitable for interventional surgery and requires open-heart surgery, the cost of surgery is relatively high, with an overall cost of about 50,000 RMB. At present, most of the cost of atrial septal defect treatment in all provinces can be reimbursed through medical insurance, and many places have charitable funds for precordial diseases. The cost of atrial septal defect surgery is not a heavy burden for families, and even some poor families can have free surgery or funding to help complete atrial septal defect surgery. Because of atrial septal defect, as long as the child receives the surgery in time, the child can be restored to normal, just like a normal person. Therefore, treatment must be carried out as early as possible to ensure a better recovery of the child’s health.
