Isolated Right Aortic Arch

Hello, I wanted to reach out for some support and advice really as I’m going out of my mind with worry.
So at our 20 week scan it was advised they could see a right aortic arch on our baby, we were really upset and confused as to what this meant.
After a fetal echo it was confirmed this was the case and thankfully didn’t see any other heart differences, everything seems to be developing as expected.
We also had an amino done which came back fine to rule out any genetics concerns. Out of fear I’ve since had a follow up scan at 24 weeks which confirmed they see no other heart differences and it still is a right aortic arch in isolation. We have another scan in a few weeks time, this is more for my reassurance and anxiety rather than because it’s needed but what if they see something else, could this now change?
Has anyone got any experience with this? If so, please can you share? I am looking for realistic and if possible positive stories to ease my anxiety.
Im so concerned about what is to come, if something could have been missed and so on.
Any help would be appreciated, thank you xx

This page from Brompton is very comprehensive (though not especially simplified considering it's intended for a lay audience - may be worth feeding through AI to simplify?)
