Hello, I had my surgery 4 years ago at 54, I was in great shape physically as I exercised frequently and never smoked, my surgeon gave me over 99% probability of no complications based on that and suggested I had it taken care of sooner than later, mine was larger 5.2, and I’m a smaller frame. I couldn’t wait to have it fixed, I was healing from leg fracture surgery (how they found the aneurysm) so had to wait a bit, but 3 months after leg surgery I had my open heart. Not going to lie, it is not pleasant but I recovered quickly, out of the hospital in 5 days, back to work in 3 weeks. I slowly went back to my workouts, limited by both leg and chest but 4 years later I am at full work outs (can’t run anymore because of the leg, but bike and swim often)

At the size of yours I think surgery is just a matter of time , I would consider taking care of it when your body is at its best and that may be now.

Hope everything goes well and if you have any questions about surgery, etc just let me know

Good luck
