I am surprised they are not doing the Aorta. My doctors always said whichever triggers surgery first will get both replaced. Keep a positive attitude, get up and start walking as soon as they tell you and keep busy not to dwell on your surgery. I was working right away, had my laptop and it kept me busy and mind off what I was going through. After first days, once they remove most of the tubes and stuff it is liberating and you will be feeling great. listen to the doctors. Keep a pillow close as coughing or sneezing will suck big time. Best of luck.
