I'm so sorry. I hope she continues to improve quickly. When is the baby due? Is she in reehab or still in the hospital? Either way, I assume she is getting very frequent ultrasounds of the baby? There is really no way to know for sure about the health of the baby and his response until he is born. I would surely want a neonatologist present for the birth besides just an ob md. With an EF of 20%, and recent history like this, is there a planned c-section once the baby has the best chance of developed lungs. Are they trying to ready the lungs ahead with surfactin? I don't think they can completely go after her cardiac care until the baby is born. She will likely AT LEAST need a dibrillator if they haven't given her one alreay. Besides her history, an EF of < 35% is an indicator for an AICD- im,planted defibrillator. If you never need it, no harm done, if it fires ONCE, it has saved your life. At the hospital I work at, people with an EF < 25% get evaluated for transplants. First they will see what can be done with treatments to see if anything can bump up that ef. Hope that helps. It some scary stuff, but knowing helps. If it is completely pregnancy induced, I'm not sure of the stats but maybe much of it can resolve. I certainly recommend an ongoing conversation with God. It helps.
I am so sorry to that you and all have had such a frightening experience.
I see you post has been up for 7 hours so I respond even though I don't have any knowledge that will help.
Clearly the situation is improving, and that has to be a relief. The overall condition is very complex but should be something your doctor(s) can help you understand better.
