Children with ventricular septal defects definitely need surgery to repair the defects. The presence of ventricular septal defects will cause changes in the hemodynamics of the heart, which may have an impact on the normal growth and development of the child, especially if the area of the defect is relatively large, which will reduce the volume of blood in the circulation and increase the volume of blood in the pulmonary circulation, thus the probability of respiratory infections is greatly increased, and it may also affect the child’s normal growth and development. Regarding the cost of the surgery, it depends on which type of surgery is used, if it is a blockage treatment, the approximate cost of the surgery is around 20,000 to 30,000 dollars, if it is an open surgery needs 50,000 to 70,000 dollars.
