I'm not on the other side yet, so I can't compare pre and post.
But in Mid April, I did a 150 mile bike ride over 2 days, 75 miles per day. We knew the aortic valve was down to 1 cm, but without symptoms, it seemed safe enough.
Then about 3 weeks ago, I consulted with a surgeon who had a CT done. My ascending aorta was 4.3 in Oct, 05, and now it is 5. He recommended surgery, so I looked at the AHA/ACC guidelines and they also recommended surgery. So we scheduled for July 7.
Sometimes I think I have symptoms, but I can't really tell. I've cut back on working out and when I ride the bike, I keep my HR under 120. If I go up a little hill or hit a strong head wind, my HR will go from 110 or so to 125 pretty quickly, and I just back off.
Right now, I just want to get it over with. If your valve is really interferring with what you want to do, it is probably time to find a surgeon and see what he or she says.
