@janemc The lesson learned, I guess, is to know what expertise all these people bring to the table. My GP has the best communication skills and sees a much wider variety of patients over longer time periods than any of the specialists. So it seemed reasonable to ask her for a reality check about long-term benefits/complications.

The other thing is not to let anybody rush you. Take the time you need to absorb the info you need to make your decision. The cardiologists understand the mechanics, but only you can put it all in context to see how it will affect your life going forward.
