Right Aortic Arch - 19+3 anatomy scan

I just had my anatomy scan (19+3) with Maternal Fetal Medicine. Our dr. referred us to MFM because my husband had a mild heart defect at birth (small whole in heart that closed over time, caused no issues and did not need surgery or treatment). The doctor today found that our baby girl has a Right Aortic Arch. I'm scheduled for an appointment later this week with a cardiac specialists for an echo. Does anyone have experience with this? I'm obviously very much so freaking out.

The doctor did say the arch appears to be isolated (which would be best case scenario and potentially cause no issues in the future) but there is the small risk of DiGeorge syndrome. I'm kind of at a loss here of where to go from here. She said the only way to diagnose DiGeorge would be an amnio synthesis which comes with its own risks so idk if I would pursue that or not... any advice is much appreciated.
