It sounds like your aneurysm is likely to be familial or genetic. The thing I would focus on right now is your blood pressure. Certain exercises can spike it- but you also want to keep it in check on a day to day basis outside of exercise. I have a 4.8 at the root and originally a suspected genetic component because of my brother’s sudden death from a heart attack. We don’t know if his heart attack was aneurysm related because there was no autopsy. I have been to both Cleveland Clinic and Mayo, and they feel that mine is likely congenital- but not due to a genetic elastic tissue disorder. Like you I have health trileaflet valves. If they had determined it was a genetic disorder issue, they both were recommending I consider surgery because I was in the 4.5 to 5.0 range. I would have never known about my aneurysm if I hadn’t gotten the tests after my brother died. The knowledge that we have this is a bit unnerving- but it is such a gift to know because we can take the necessary steps to take care of it. Best of luck to you!!
