The surgery for tetralogy of Fallot is more complicated compared to ventricular septal defect, atrial septal defect, and patent ductus arteriosus, so the cost is still relatively high. The specific cost, depending on the patient’s age and physical condition, is required. If the child has the surgery at 7-8 months, the pulmonary vascular development is also better, and there is no definite hypoxic attack, the postoperative recovery is usually more satisfactory, and it is about 50-60 thousand Yuan. However, if the child is younger, such as around 6 months old or even more than 5 months old to do the surgery, the intraoperative requirements are higher, the postoperative treatment time is also longer, the care time is also longer, and the cost is likely to be higher, about 60-70,000 Yuan or even higher. Older children also have more blood vessels, poorer heart function after surgery, longer hospital stays, and higher costs, perhaps even more than 100,000 yuan in some cases. In short, all costs cannot be generalized, but need to be judged according to the severity of the child’s condition, the recovery time after surgery, and the presence of complications.
