thanks for your query on health magic care
at present there is no need of surgical intervention for this small ASD .
ASD > 8 mm diameter that will rarely close . small ASD may be closed . if ASD did not close by 2 year this will rarely closed .
most of the case of ASD did not cause problem in life . Rarely they will have heart failure
and not to be fright if ASD need surgical intervention. operation is small and not much complicated as truncus arteriosus
medicine did not close ASD. heart failure can be managed by medicines but if heart failure occures that is indication for surgical management.
