Annie,
I'm not sure what you mean by repaired by angioplasty. Often times an aortic aneurysm is repaired with a graft when a bicuspid valve is replaced. Angioplasy refers to ballon dilitation of a blood vessel and is usually performed for narrowing of arteries.
Sometimes at the end of a aortic repair an anuerysm can form. I would be interested in interval change of your anuerysm, and 4.9 cm lies within the range that is usally followed medically unless there was evidence of rapid expansion. I would probably repeat a scan in 3-6 months and see if there was any significant change. If not you could probably be followed yearly.
good luck
I really don't know much about aortoplasty, but it seems to me that it is really not done anymore, for whatever reason. With a brother who died at 33 of an essentially unspecified cardiac event, I am going to trust that I cannot alarm you. If I do, I apologize. IMO, you should be evaluated at a large, high-volume center with an aortic clinic--there are several such centers in the country, Cleveland Clinic among them. I can't imagine having peace of mind in your situation without a game-plan from a surgeon who has dealt with aortic aneurysms adjacent to aortoplasties. Even at a regional heart center I would guess you might be the first--or one of a handful--that a surgeon has seen.
I visit a forum for heart valve replacement patients and their families where you would undoubtedly find valuable emotional support and ample comisseration, but no medical advice. It is called valvereplacement.com. Go there and register. And hang in there. ~~~HUG~~~

Thanks again for your concern.
There is a lot of information at www.bicuspidfoundation.com.
Take good care and keep up the posts on your status if you can...I too have a bicuspid valve and ascending aortic aneurysm and have found that being proactive in my care saved my life.
