Multiple echogenic foci seen on baby's heart

Had just went for my 20week prenatal anomaly screening. The tech did not say anything to me but on the screening form to be forwarded to the doc, she had noted down special notes that say 2 echogenic foci seen at left side of the heart and 1 focus seen on the right side. Does anyone have some advices or experience to share? There is nothing I can do now except waiting for the report/call from doc. I'm worried sick 😭.
