When you say natural healing, you mean to see if it closes naturally?
It can reduce in size but if large, it is unlikely it will close completely. I would have a discussion with your Doctor because they may decide to try and keep the heart more healthy using medications, and see how much the VSD shrinks. However, there are things to keep in mind. Brain development may be reduced in the first months, as nutrition delivery is a problem with heart failure symptoms. The whole body growth could be inhibited. I think an expert in this field needs to have a discussion with you. Surgery is safe, there are no complications with over 99% of operations. If the VSD shrinks a small amount, and health is maintained with meds, then a child would probably not be able to achieve the same exertion as other children in sporting activities etc. It would also mean many hospital visits for monitoring.
