Yes! Only difference is I'm 40 and was diagnosed at birth. My first suggestion would be to find an Adult Congenital Heart Disease clinic in your area. If you have a good Children's Hospital near by, there may be a partnership with an adult hospital for cardiac.
Cardiologist that specialize in congenital disease and/or pediatric cardiologist are your friend. They understand the anatomy better of your heart. Also, if the time comes, you will want a pediatric surgeon, that understand s and sees these types of cases everyday.
Unfortunately, I had my valve replaced when I was 37, due to endocarditis. I was getting close to needed to replace the valve but I never expected it to happen that way. We couldn't repair the AA though, because of infection.
The surgery wasn't nearly as bad as you wouldn't thought, and I ran a mile at 7 weeks post-op.
I am also very active, strength training, TRX, Yoga, Pilates, circuit training. I'm careful about the amount of weight I use and straining, not wanting to elevate my blood pressure quickly, and I also take a beta blocker to help ensure I don't have the BP rushes, which can expand the aorta. Of course I didn't have high BP before, so I do have to take salt tablets to keep my pressure normal as it will drop low w/ the BB.
Best of luck and feel free to ask me anything you'd like.
