Beating heart transplants tested

Andrea Ybarra's donated heart was beating rhythmically by the time she awoke from the grogginess of her surgery.

Lub-dub. Lub-dub. Lub-dub. In fact, it was warm and pumping even before doctors transplanted it.

Ybarra belongs to a small group of people who have had a "beating heart" transplant, an experimental operation that's mostly been done in Europe. The donor heart is placed into a special box that feeds it blood and keeps it warm and ticking outside the body.
