I had Aurotic Valve Bypass replacement surgery and two stents in 2005. Reassure your husband it will be fine! He will finally get to breathe normally and enjoy life. He MUST do as doctors tell him after the surgery for a short time (walking, not lifting anything) then he is free to run like the wind! I made a trail walking around our place here as soon as they said "WALK". It looked like a funny little parade with the dogs and chickens walking along behind me. I had to use a cane for a few days but then my speed increased and the cane went bye-bye. Tell him to hang on to his little pillow. It will be his best friend for awhile (behind you of course). Our prayers are with you and your husband through this until he is well. Know that prayer warriors are in full armour and out in force for you both. any questions I can help with just write and I'll try to give any help I can.
