Hello and welcome to HealingWell. I am sorry to hear of the problems your Father is experiencing. I do know that each facility has their own eligibilty criteria for being accepted into the transplant program.
Doctors evaluate potential candidates individually. You must be willing to adhere to a regimented medical program and work closely with your medical team to maximize the benefits and reduce the risks of transplantation.
I would suspect that a social worker has been assigned to your Father and this may be a good person to talk to re your concerns as to why you Father is being excluded access to the transplant list. Reading from the University of Michigan Hospitals website it states, " The heart transplant specialists at the heart transplant center will determine whether a patient is eligible for a transplant."
