IEF / bright spot on heart

So I went in for a 2nd ultrasound because my baby has a bright spot called an IEF on his heart... Basically it's a calcium build up on his heart that isn't dangerous at all and usually goes away... The doctor said this is a soft marker for Down syndrome / Chromosonal defects, but they find it in a lot of babies without DS too....All of my blood work came back good and she said I have a very low chance of this baby having any type of defects, especially since I'm only 20 & my results were good. I'd love him either way--- but has any other moms out there had this happen? What was the outcome for your baby?
