Mom2Izzy and Nancy Jane, you're both quite welcome. It's a great opportunity for me to reflect back on that process. The one thought that keeps coming up and up when I do reflect back, is just how easy the whole thing was, on balance. Sure there were trying moments, and the fear and anticipation themselves were a little tough at times, but the actual events leading up to, including, and recovering from valve replacement surgery, were never hard, and rarely even unpleasant. I suppose I was lucky too, with few complications (some pretty intense A-fib which lasted hours, and a kind of grody infection in my incision were the worst of it), but I think most of us get through without much more trouble than that.
Oh! One more thing I remember about the cath. When they dumped the large quantity of dye, or medium, or whatever it was called, to see the flow through the aortic valve and aorta itself (I think), it was either warm or cold, I don't remember which. What I do remember is that it was the most curious feeling as it spread around my body. To be either warmed or cooled from inside like that. Not at all uncomfortable, just unusual. Actually, I kind of liked it, but that might have been the drugs.
