Update

The surgery went well.  My dad was a real trooper through the hospitalization.  He remained upbeat unless he was in a lot of pain.  When he started joking with us and the nurses and telling stories we knew he was well on the road to recovery.  He came home this afternoon.  We still have to wait the results of the biopsy, have spots on his lung checked out and then go ahead with mitral valve repair/replacement.  He has been tired and has had very low endurance for the last while and they determined he needed mitral valve replacement or repair.  The cancer was discovered because of pre-op blood work for the heart surgery, so it was discovered early. Thanks to everyone for your support.
