My aneurysm was found after an MTB accident, I broke my leg and needed surgery to repair the fracture. It was already at 5.2 cm when found, so the Drs that found it recommended I saw a specialist surgeon ASAP as in their opinion I needed to have it repaired. The surgeon agreed, his take was it was very large for my body size (I’m 5’6”), I had family history of ruptured aneurysms and based on my general physical condition surgery was very low risk. I needed to be able to walk through so I had to wait a couple of months and had the surgery. So I don’t have a growth history, in my mind the accident saved my life. The only reference I have is that I had an echocardiogram in 2011 and they told me I had a bicuspid aortic valve but there was no mention of aortic dilation, they either didn’t see it or it didn’t exist back then. That was 9 years before it was found
