Hi Doclewis - you and I had the same procedure - except mine was 3 1/2 years ago with the Carpentier Edwards Perimount Magna Ease Aortic (21mm)... things are going very well! I was 51 at the time, and had quite a roller coaster ride trying to decide between mechanical and tissue. I ended up going with the tissue valve because I already have thin blood. I am not sure if it was the right choice, because I am quite active and have read that active people end up with stenosis on their tissue valves sooner than not, but I can't go back now. I am assuming the repair of the aneurysm is a one time thing? (I hope) I would love to know in advance how long my tissue valve will last, but that will be a mystery until it starts going down hill. Hopefully many years to go!
