@Drew944 I think you are trying to find a way to blame something you did for this aneurysm but it may not be anything you did but just a genetic weakness in the aorta. In any case, don't spend time trying to find an answer to a question that doesn't need to be asked. You have an aneurysm, you can't change that and all you can do is assure your cardio is monitoring it and that you are following the cardio's direction about what you should and should not do. It is important to keep your blood pressure under control as elevated blood pressure can put pressure on that weak spot in the aorta. If you smoke, stop right now. I believe that an aneurysm can remain stable and not in need of surgical repair for years and years and years. Not sure about "forever".

The longer we can remain stable, the more likely there will be a different and less invasive repair available. And the more likely that something else will "get us" before we need a repair. Our bodies age and we won't live forever; our best bet is to follow the cardio's direction and enjoy our lives. We don't "win" by worrying.

And if down the road I do need surgical repair, I will have it done and be grateful that medical science has advanced to the point that such repair can be done with a positive outcome. And if I get really, really old and perhaps not likely to survive such a surgical procedure, there is another procedure already available for placing a stent in the aorta to add strength.

I will not let this diagnosis steal my joy in life and you shouldn't either. You have children who need you to be joyful and not consumed with (unnecessarily) worrying about this. Place your trust in your cardiologist and he will alert you if you need to do anything further.

I wish you well.
