Welcome! I am assuming from your screen name that you are retired or semi-retired. Your situation sounds similar to mine back in '05. I had an aneurysm, ascending aortic, that was measured at 5.5, and a valve that was leaking "catastrophically" as my surgeon put it in his surgery report. I chose the stentless, porcine Medtronics Freestyle, combined root/valve replacement, which is a relatively new replacement device but seems to have a promising track record so far. Sounds like you have made your valve choice, and there are many good ones, so I am not trying to influence you in that decision.
Glad to have you here with us. As others have suggested, you could do some searches on here and find a lot of discussions of preparation for and recovery from this type of surgery, Direct answers are good, too, so ask away if you have specific questions and a bunch of folks will offer their slants. I found it very helpful to have my family involved in looking after me for several weeks. They really spoiled me and I appreciated it. I found a recliner very helpful b/c I had trouble sleeping in a bed for some time. Just napped in the recliner. Good idea to have a pill organizer -- my daughter helped me with that. Some DVDs on hand of movies you've always wanted to see. Pitcher of fresh water within reach. Of course the spirometer will be your constant friend -- a useful device for gaining full lung function.
You should do fine. We will be here for you.
