Hi, Larry, before surgery, I worried a lot about how much of an invalid I would be upon returning home. In truth, one persons experience cannot be directly related to your own, still, most people should be able to move around and do normal light tasks around the house and care for themselves when they return home. You might need to take the stair more slowly at first but they would not normally be a problem. Your legs are fine after the AVR. The big problem is pulling with the arms and lifting. The one problem I would see with orienting yourself towards the upper part of the house is that one might tend to avoid getting out as much as necessary. Upon returning home, you have only three primary things to focus upon. Resting, eating, and walking. You will likely find the loss of stamina surprising but the good news is that it returns quickly. In the mean time, when your body tells you it needs a nap, listen to it. If you are going to heal properly, you need to eat a good diet. Some have suggested heavy on the protein. Walking will spur on your recovery more than anything else. Don't worry about distance. Several shorter walks will do quite well during those first three weeks while the incisions are healing. Walking will also improve your appetite and help you sleep better.
I did get a recliner before the AVR but I never slept in it at night. That said, I found it a wonderful place to nap and use my notebook computer (with a lap table). Mine is the kind with a lever on the side and I never had a problem with it. You might go to a store with a number of different ones and try out each of them paying attention to comfort and ease of operation.
You are very likely to find that although you will be week at first, strength will return rapidly and movement less of a problem than you may presently imagine. Your recovery is something you control. To get the most out of your recovery time, you might treat it like you would if you were training for some event and, in fact you are. Make a schedule for yourself and try to follow it. Try to walk at regular times instead of just when you "feel" like it. Look for things you can do. You might need to make several trips to load the washing machine but who says you have to carry everything at one time. After a couple of weeks, you will find that you still need to rest but are less inclined to sleep; it is a good time for writing or reading. Recovery can be a surprisingly good time, Larry. I encourage you to make the most of it.
Larry
