Hey Book
I'm in the same position you are. I feel great and, though I did have one fainting spell, it's hard for me to believe I need an AVR.
Unlike you, I have had a great exchange with my surgeon. I spent, quite literally, two whole hours in his office going over the procedure, the recuperation, the various valve choices from both the patients perspective AND the perspective of the guy who has to implant it.... we actually ran out of things to talk about and I got an earful abut his college hockey team.
Most important to me -
He started in the military (My dad was a Navy Doc and I know how well those guys are trained)
He's done over 1500 of these procedures
He's a very approachable guy
He called me back to answer some questions I forgot to ask initially
He never played hockey professionally
I think the whole trick to this (for me at least) was to get it through my thick skull that I will be out cold for the whole thing and only partly awake when they yank my tubes. Even then, I have the promise of the anesthesiologist that I'll be well and truly doped up, so I should not be too put out by it. Unless something goes wrong (and why assume that?) I'll go in, get prepped, pass into a deep slumber and awaken with a big scar on my chest. Yes, the following weeks will probably suck but my wife and family will take good care that I don't do anything stupid and, three months from now, I should be fine.
You're actually in a good place right now.You've done all your pre-op stuff so there's nothing you can possibly contribute to the process now other than your consent. You will take a nap in the morning and wake up in the afternoon with a pain in your chest and high as a kite. They even give you a self dosing morphine pump you can preoccupy yourself with. YES!
So take it easy.
BTW, I have had a few operations over the years and all I can remember from any of them is the hot nurses and the sh*tty food.
I wish you the best of luck.
