Dear Tam,
It's hard to say without knowing what all the data are. However, if she wants to do everything possible and is willing to take the risks of surgery then this may be the best course of action. I would recommend that she get a second opinion at a heart center. She is probably not a transplant candidate due to her age but may still be a good surgical candidate. If she wants to be seen at the Cleveland Clinic I would recommend Dr. Richard Grimm or Dr. William Stewart.
My mother is on medication for heart failure:coumadin, two diuretics, and an ace inhibitor.
