Anatomy scan

So today I went for my anatomy scan. They said baby girl looks healthy which I am so thankful for! But they said they did notice an echogenic intracardiac focus or an EIF, which is a fancy name for a calcium spot on her heart. They told me is was no cause for worry so I'd like to think I'm not too worried. Just wondering if any other mamas went through this? They said its believed it could be linked to DS, but no significant study for it. I don't have any other markers for DS, which is why I'm not too concerned. Just want to hear other stories to completely put my mind at ease. Thanks!
