Not true. I've been involved in atudies where we cut the heart out of sheep and then implanted a pump to replace it. One animal had the pump strapped to its back. The animal bumped up against its pen one day and broke one of the 1/2" tubes free and the pump (artificial heart) sprayed blood all over the pen and the animal bled out. We discovered it in the morning. I'd rather do just about anything than that. Worst death imaginable.
