###Human: What should be done for supravalvular pulmonary membrane in a baby? ###Assistant: Hi. This condition is more of pediatric cardiology rather than adult cardiology. However, I think that if the stenosis is minimal then it should only be observed at this stage with regular yearly echos. If the stenosis progresses and become of severe degree, then this can be managed with means of balloon dilatation in the first instance in young age group and only if this fails, then she can have surgery. I wish your daughter good recovery and happy life.
