One must assume that she gave permission. But it does raise an interesting question for which someone may have an answer. If during a surgical procedure involving a transplant or organ removal, and one signs a consent form for the procedue, who in the end "owns" the organ removed?
I assume most bad tonsils or spleens end up in the hospital incinerator, but is there a special consent form aloowing study or, in the case of this lady's heart, display and what happens to the heart after the exhibit ends.
