Hello, congenital heart disease, ventricular septal defect about 8 mm, if you have done ventricular septal defect repair, you can get married and have children, and it will not be inherited. If there is no operation, it is recommended to operate as soon as possible. Adult congenital heart disease ventricular septal defect, it is suggested that "ventricular septal defect repair" requires surgery as follows: 1. If there is a heart murmur, it will affect school employment; 2. Both patients and parents have psychological burden; 3. Ventricular septal defect may lead to infective endocarditis, conduction bundle damage and aortic valve insufficiency. 4. In mature hospitals, the success rate of ventricular septal defect repair is basically 100%. The total hospitalization cost of "ventricular septal defect repair" is about 1.8 thousand to 20 thousand, which may be obviously different in different regions and hospitals. In a large cardiovascular surgery center with mature technology, the success rate of "ventricular septal defect repair" is basically 100%. After the cure, it will be the same as normal people. Does not affect your work and life. If it is an operation, it is recommended to repair the ventricular septal defect through a cosmetic incision under the right armpit.

Compared with mature cardiovascular surgery, interventional occlusion is very risky, so at present, developed countries strictly limit interventional occlusion treatment. Only a few diseases with high surgical risk, such as muscular ventricular septal defect and patent ductus arteriosus, are treated with interventional therapy. Don't ignore the greater risk of intervention (including the harm of radiation) because you are afraid of a larger skin incision.
