I am 20 weeks pregnant with my second child, and was shocked to be told last week that my baby has a heart defect called "persistent superior left vena cava", which is in essence an extra vein going into the heart. On its own this is often not a problem, but it can be linked to chromosomal abnormalities. In addition the baby is missing an artery in the cord, which I think is linked to the heart defect, and can lead to a problem with development. Has anyone had this problem and can give me any reassurance?
Thanks.
