UK doctors perform unique heart operation

A girl whose body began to reject a donor's heart has had it removed because her own heart is now strong enough to pump her blood on its own again, her doctor said Thursday. Doctors transplanted a donor heart to "piggyback" on Hannah Clark's diseased organ a decade ago, said Dr. Victor Tsang, one of the 12-year-old's surgeons. When she developed severe complications with her immune system recently, doctors at the Great Ormond Street Hospital decided to remove the donor heart so they could take her off the immune suppression drugs she needed to keep her body from rejecting it. They had determined that her own heart had recovered sufficiently to work on its own, Tsang said.
