Apparently the same organ can be transplanted more than once. It's called a Domino Transplant and forms the basis of Canadian actor Matthew Edison's playwrighting debut
The Domino Heart. It's made up of three monologues by people who, whether literally or metaphorically, have at some point had possession of the heart in question, that of a writer killed in a car crash. First up we have the newly-widowed Cara (Amanda Hale,) who like many people dealing with grief blames herself - in her case it's because she and her husband were arguing at the time of the accident, about an affair she had had ten years previously. On top of this, the fact that a heart her husband said belonged to her, will now be harvested to be given to someone else, makes her want to say quite a literal goodbye to it.
