The cost of atrial septal defect surgery is mainly divided into two cases: the first case is the use of minimally invasive methods, the use of puncture devices, catheter devices, and then the sealing devices, the whole cost is about 35,000 yuan. If the conventional open-chest method is used, the operation is risky and the cost is relatively high, the basic cost may be around 50,000 yuan, most of them choose minimally invasive blocking, of course, there are also individual cases that are not suitable for minimally invasive, mainly because the defect site is special, there is no special development to completely block the defect site, only open-chest surgery can be done. So the cost is basically about 30,000 yuan to do minimally invasive.
