I don't know... i took a whole bag of stuff, books, Ipod, crosswords, etc... i used my Ipod to listen to pre surgery and never opened the bag again through my stay. I couldn't concentrate on anything. I would move things to lower shelves so that you can reach them. A shower chair was great to have when I came home.. and lots and lots and lots of pillows.
Just wanted to give you a bit of encouragement. I'll assume you are having the Maze due to some Arrythmias since I really see no other reason to do one. I was having them at least 8-9 a day before my surgery. They also did a Maze on me also... i am 7 weeks post op now and haven't had a single arrythmia. I am also not taking Anti-Arrythmia meds anymore either. So I hope that makes you feel good and hopeful. Good luck to you.
