The fact that the baby has congenital heart disease
is probably indisputable. However, it is impossible to specify the answers to your question unless you tell me which problem is present. Assuming that you are referring to one of the valves of the big vessels that emerge from the ventricles of the heart, it is possible to open their constrictions with a balloon valvuloplasty
It is not possible to medicate the child against rubella
, because it is a viral illness, against which antibiotics are useless.
From the entire history, it seems as though your baby has aortic stenosis
. If so, she will have automatic enlargement of the left ventricle, thereby increasing the size of the shadow of the heart on the X ray
Do let me know the further progress of the child and feel free to follow up if needed.
