This is pretty off-topic, but who knows—maybe you could use it somehow for a cardiology meeting? Nathan Sawaya is an artist whose medium is candy, and he made this lovely rendition of a heart because, he says, "I'm not a fan of Valentine's Day. It is a made up holiday and makes more people feel sad than happy. It can make your heart feel vulnerable. Almost edible."
(Thanks to BoingBoing for the pointer.)
