the original reason for this follow up cured itself, but she does have a hole in her heart the doctor said it is normal some but it may go away.. but sometimes it doesn't. it should not cause any problems
hopefully it's nothing too serious. my son has a hole in his heart that's bigger than most of the holes newborns have. we have to wait until he's 22 lbs to get another echo to see if it's closed on it's own. if it doesn't they have to use a catheter or surgery to close it. the heart is scary
