Anatomy scan/ spot on heart

We had are anatomy scan today ☺️🤗 it was so much fun seeing our little girl moving around and smiling. We also were told she has a spot on her heart and that the doctor has no concerns. But I’m a little bit worried. But we did do a genetic test and tested low risk and all her other parts measure well and she’s measuring big like her two brothers before her, 75 percentile. But, has any had this and everything was ok with your little? Guess I’m looking for some extra peace of mind...
