Children with Congenital Heart defects can present with repeated chest infections.
But that does not mean that all kids with chest infections or wheeze have a heart defect.
How is her growth? Usually kids with heart defects and repeated chest infections, do not thrive
Since you had a doubt during your pregnancy
, its better that you have an ECHO done now.
Yes she can get allergy/ wheeze like any other children irrespective of the status of her heart.
If she has recurrent wheeze- along with albuterol
for rescue, your doctor may advise you medications that help in preventing such recurrences like Montair. You may discuss with your doctor regarding this.
Hope you find my answer helpful.
Wish your daughter good health!
