Hi Littlemommabear - Good to see you here!
Hey, don't worry too much about your PFO procedure. Sure, any procedure carries risks, but heart catheter procedures have become so commonplace now, placing stents, performing ablations, closing septal defects, that most cardiology practices in the US perform many procedures per year and are very proficient at it.
You're going to be up and around, and probably feeling better in no time. Hey, if you're interested, I have an anecdotal story you might be interested in about a professional football player.
