Hi Kmailloux, my wife just discovered this blog and encouraged me to join and share. In late 2019 I had an MTB accident and broke my leg, during the surgery prep they discovered I had a 5.2 cm ascending aortic aneurysm also linked to a biscupid aortic valve, I was 54 years old then and exercised often (not as much as you) and in very good physical shape. My aneurysm was already within the size to consider surgery, there’s also a genetic factor in my family that makes us vulnerable somehow to getting aneurysms, and in some cases they have ruptured, none aortic though. I spoke with a surgeon and a cardiologist (awesome both) who specializes on aneurysms and their relationship to bicuspid valves. My surgeon told me that based on my physical fitness and overall health the surgery would be minimum risk, and I could return to my normal life, it could not be done immediately since my leg had to heal enough to allow me to walk after heart surgery. I made my mind immediately, the stress of knowing what I had was unbearable, every time I felt a little pain in my chest I jumped, they were all mainly muscular. I had my repair surgery in early 2020, and as my surgeon said, it went with no issues. Not going to minimize it, it is painful (not as much as the leg fracture though) and as I was recovering there were moments I felt the worst I felt in my life, but I was out of the hospital in less than a week and back to work in 3. I work out with no restrictions except the ones left by the leg fracture (hard to run, but I continue biking). Surgery is a personal choice but thought I’d shared if you ever consider it. I see my cardiologist every year mainly to monitor the bicuspid valve, at some point it will have to be replaced, in some cases that cannot happen endovascularly if the aneurysm is still there. My valve was still in good shape when I had the surgery so they left it knowing they if/when it needed to be replaced it could be done by catheter.
