James, when my Cardio started talking about surgery, I wasn't feeling great but still not too bad and I sort of expected to be the same by the time my AVR date arrived. Instead, each week I felt worse and worse. My Surgeon said that it is not atypical for valves to degrade pretty quickly once they start to go. Still, it made getting things ready at home every so much more of a strain when feeling more ill with each passing day. Hang in there, it will be better. Hopefully, you will share my experience and feel better as soon as you get to leave the ICU.
