Eif problems in ultrasound

Anybody have any problems with echogenic intracardiac focus while pregnant? I’m 33 weeks and went for a nst today and I got an ultrasound and they saw a light spot on baby’s heart and said it was related to the baby having Down’s syndrome. But my nipt and quad test were all normal. I’m so confused at this point because they have been seeing it at past ultrasounds but just now wanna tell

Me about it.

Has anybody had this problem and baby was alright?
