Hi, Barbara,
I have HCM also, diagnosed following a cardiac arrest in 2010. You are most definately not alone. I am a patient at Mayo and most impressed by their knowledge. The questions Cyna suggested are excellent-it is important to know that your heart is being trusted to people who have the expertise to successfully do the surgery if needed. If you can't fly, would train be an option? It's slow and a bit of a pain (though I LOVE trains) but it might be possible. Please let us know and know that we are here to support you.
