Orlando Health and Florida Hospital, Central Florida's two largest hospital systems, have submitted competing bids to start a heart-transplant program in Orlando. No Florida metro area has more than one heart-transplant program, making it unlikely the state would approve both Orlando applications. But the large east Central Florida organ-transplant district that includes Orlando currently has no heart-transplant program, so it's unlikely the state would turn down both. State regulators will decide by Aug. 22 whether to accept both, neither, or just one of the proposals.
