Hi Glimmer...I have the same aortic aneurym except I'm at 5.3 cmm. I've been followed for years and just found out today that it's time to repair it.Fun...I've already had 2 coarctations of the Aorta repaired. one at 12 yrs and the other at 35 yrs. I'm now 42 and we're going to replace the aortic valve at the same time. I was born with all this and grateful it can be fixed. It took a long time for mine to grow bigger, and yours may or may not change. Just keep up with your doctor visits and meds if they have you on any. My doc told me that the meds exstend the life of your aorta, keep the pressure down and not wear the walls out. A ct scan every year is a must to...take care of yourself.
