If you can get those kind of rides in with your doc's blessing, that's GREAT! I know it's prbably not enough, but it sure beats not riding.
I have a 20 year old Vitus-Cilo set up on a trainer in the basement. That was a really neat old bike. It has glued thin tube aluminum frame. 10 years ago or so I had it upgraded with an Ultegra gruppo. I used that as my only bike until 3 years ago when I splurged and got a Merlin.
I don't love the trainer...too boring. But if I had to go somewhere to ride a trainser, I know I'd never do it. If I break it up into multiple 1/2 hour sessions it's not too bad.

Eddie, I don't know if your docs or anyone suggested it, for some reason I noticed valve replacements don't get told about it as much as other heart surgeries. But you might want to look into cardiac rehab. it is kind of like a gym, but you are monitored and the tech let you know what/how much you can do, so you can get a good dea and not find out what it "too much" the hard way. Alot of people that weren't really interested in going ended up thinking it was pretty great and recomend it to everyone. Lyn
