Testing new cardiac techniques and devices on live animals requires proper oversight, regulation, and considerable expense. To overcome this, researchers at North Carolina State University developed a machine, specifically intended for study of mitral valve repair, that can pump a pig's heart straight from the slaughterhouse. "Researchers can obtain pig hearts from a pork processing facility and use the system to test their prototypes or practice new surgical procedures," says Andrew Richards, a Ph. D. student in mechanical engineering at NC State who designed the heart machine.
