Without evaluating your son, I cannot tell you the chance of these VSDs closing. If, in fact, you say that they are small, then it does not matter whether they close or not. What matters is how much blood is recirculating from the left side of the heart to the right side of the heart. If a small amount is going across the holes, and he is eating well without getting out of breath or getting sweaty with feeds, then it is likely not to be a problem for him. If you find that he has these problems, then his defects may be larger than initially thought, and he may require surgical intervention to close them.
