Hypoplastic Left Heart Syndrome (HLHS)

The structures of the left heart are too small to provide all of the body’s blood supply. Sometimes, the left heart structures might be so small that the diagnosis is obvious. However, there are some babies where it is hard to tell if the left heart is just barely too small or just barely big enough.
