@lsheerin, I agree that the waiting is a difficult period of time, especially as one's health continues to fail, as was my experience. However, I was fortunate that the wait resulted in me getting 2 beautiful organs. I had a simultaneous liver and kidney transplant, which is one donor, one surgery, and 2 organs that were a good match for me.
I hope that your husband's transplant team explained to both of you, at the time that he was evaluated and listed, that organs can be rejected for a multiple of reasons and that the MELD score is just one of the criteria for getting the surgery.

How is hubby doing? Has he returned to any of his former activities?
