Dear Devorah, thank you for your question. This is a controversial area, as you have found out. It's encouraging that the size of your daughter's ASD is small (< 1 cm) and she is asymptomatic. The problem with repairing the ASD as this point is that the tissue used to repair the defect may not grown as she develops. If she is followed closely by a cardiologist and she is monitored for the development of symptoms, then she should have a good outcome when the decision is made to repair the ASD. Thus, I agree with the opinion of the cardiologist that you have seen, but if you feel a second opinion is needed, then you should get one. I can't give you specific advice regarding that question in this forum, but I think the present course of action sounds appropriate.
