Dear sir. Actually the decision depends a lot on what complaints your baby is having and what is the structural anatomy (severity, exact location etc.) of these blockages. Hence I would advise you to personally show your baby to a pediatric cardiologist for the final decision. But in my opinion, in general, for this problem intervention (usually surgery) is required and there are no medicines or physiotherapy which can cure this. Hope this helps.
