BAV and ascending aortic aneurysms are related due to a common problem in the proteins that make up those structures. As a result, the other two aneurysms are also related to that as well. Just like with the aortic aneurysm, those are also at inceased risk of rupture. I am assuming that you are not experiencing any symptoms from either one of them. The measurements that you mentioned above are a little worrisome to me, they are definitely larger than what the upper limits of normal measurements should be. Again, in asymptomatic cases, the decision to operate is probably very subjective and dependent on the surgeon but in most cases rapid progressio, presence of clot or any symptoms all point toward the need for surgery. I would recommend that you see a vascular surgeon about this sooner than later. You should also compare the size of the aortic anuerysm from a year or two ago to make sure that the repair was good and that there is no further expansion.
Thank you again.
