What is the exact cost of surgery for a so-called congenital heart disease atrial septal defect that can cost? If there is only a simple congenital atrial septal defect, the cost is around $40,000. There are two types of septal defects: central septal defect, superior vena cava septal defect, and inferior vena cava septal defect. The cost of surgery also varies according to the size of the septal defect, and when the septum is larger, it is likely to cause pulmonary hypertension, which will further increase the cost of surgery and make it more difficult to care for the patient in the future. Therefore, the exact cost of surgery for congenital heart disease with atrial septal defect depends on each patient’s own condition, and most of them are around 40,000 yuan, which is the case of simple atrial septal defect without complications. Some hospitals have funds available for application, in which case the patient may be able to solve the problem for a very small amount of money.
