The Welsh girl in question has had the transplanted heart removed after nearly 10 years and so far has recovered just fine with her original heart.
A decade ago in London, surgeons implanted 2-year-old Hannah Clark with a new heart because her own heart was swollen and unable to function on its own.
Technology in mechanical devices then was not reliable enough to suit her doctors, and they left her own heart in place.
In November of 2005, her body began rejecting the second heart. Reportedly, Dr. Magdi Yacoub, who conducted the original ground breaking transplant, advised surgeons to remove it and see if her own heart had strengthened.
Surprisingly the original diseased heart has started recovering and Hannah is recovering well.
Professor Peter Weissberg, medical director of the British Heart Foundation, says the event is one of the most important in medical history, 'Surgeons have thought for some time that if a heart is failing because of acute inflammation it might be able to recover if rested.
