Hi Will3886. I see you got checked because your brother had heart issues? That points towards a possible genetic component to your aneurysm. You need to have that discussion with your cardiologist soon. Some familial TAADs (thoracic aortic aneurysm disease) lead to early dissection. Not all, but some. If you show one of these genetic markers, the algorithm for the timing of repair is altered accordingly. I urge you, with a 4.5, to have this discussion in order to make informed decisions. I to love hiking! I used to run and I get your desire to let loose on those amazing trails! Good luck!!!
