20% Heart muscle function

My husband has 20% heart muscle function with only one artery in the back that is functioning.  He had a pacemaker/defibulator placed in his chest in November 2007.  Since then his heart has gone out of rhythm and is still unable to have it shocked back into rhythm.  His blood "warfin" level was too low  only 1.7 and now it has raised to 3.7.  I too wonder why he had to have a defib if it is not going to shock him back to normal when it is out of rhythm.  We were told it is because it is the "good" muscle that is racing and the "lower" part of the muscle that is not functioning.  He can not take amiodarone because his lung fills with fluid.  I would like to know if there are places where he can have a chance to improve his heart or perhaps a transplant?  Naturally, all would depend on his current health.
