Best of luck to you.
Those doctors and the rest of the medical teams are pretty good these days.
Nevertheless, a very harrowing experience for you I am sure.
Hope that your recovery goes well and that you get back in the saddle soon.
Used to be my neighbor out in the country...came over one day to help me clear some acreage, cut some firewood, etc.
Thought he was going to die he was breathing so hard...turns out he need 4X bypass...had it...and after about 6 weeks recover, I could barely keep up with him...
This is a good thing & you'll be much better after!
