Just happened to catch your post and wanted to reassure you that everything is probably just fine! My daughter had an EIF on her left ventricle as well. We were sent on for a level II ultrasound that showed no other markers, although I was still a little nervous for the remainder of my pregnancy. She was born completely healthy in March. They are being discovered more and more often because of better imaging technology. Also, if a mother is thin or of certain ethnic backgrounds, they are more commonly found. I hope this helps. I know it's hard, but try not to worry!
