The baby is 1 year old and was diagnosed at birth with a condition, ventricular septal defect. He has been hospitalized and reviewed several times, and his current condition is a 9mm septal defect and mitral regurgitation. The doctor said that minimally invasive surgery is possible, and since our child is covered by health insurance, we can get a discount. I would like to ask about the cost. How much is the cost of the blocking device for heart surgery? In addition to septal defects, interventional blocking is not recommended for ventricular defects in other parts of the ventricle, because: 1. Therefore, the possibility of damaging adjacent structures is greater than that of open-heart surgery, and the corresponding complication rate (tricuspid or aortic valve injury, complete atrioventricular block, blocker dislocation, etc.) is higher than that of surgery; if blocker-related complications occur, another surgery (e.g., blocker removal, aortic valve injury repair, etc.) is required to solve the problem. 2, surgical correction has a history of more than 50 years, mature experience, high safety; interventional blocking is a new treatment in recent years, the long-term effect is yet to be observed, and the limited experience shows that interventional blocking is not the first choice for the treatment of ventricular septal defect (except for some cases of multiple defects in the muscle beam). Moreover, if there are other problems such as combined valve lesions, they should be corrected surgically at the same time.
