ARSA (Aberrant Right Subclavian Artery) finding?

Hi mummies, anyone after the 20weeks details scanning and finding of ARSA (Aberrant Right Subclavian Artery) issue? While my NIPT result both Down’s syndrome and digeorge syndrome come our as low risk. Gynea said it could be an isolated case. But I’m still worrying , would like to see anyone have the experience and should I do future inversions test ( which Gynea said habe less than 1% miscarriage rate) This is my 1st baby girl. So would like to see your all’s experience. Thanks!
