I am sorry about what your family is going thru. I have seen some kids with left hypoplastic do okay, we send our kids to Cleveland Clinic and most of them have the Norwood procedure. We have even gotten a few of the kids back post op, and they do pretty well.
Is she delivering at a hospital that is equipped to take care of the baby? Or is the baby being transported to an outlying facility? We usually don't hang on to those kids for long as our cardiologists make arrangements for us to take the baby as soon as we can after stabilizing it. I believe that they put the baby on Ecmo after arrival if it is very unstable.
I have seen some kids that have no left side whatsoever and we usually let them go.
Again, I am so sorry
