“Dynamic Heart System”: The Beating Heart Machine
A new computer-controlled machine developed by scientists at North Carolina State University can keep animal hearts beating so that they can be studied for research. The machine is capable of keeping an animal’s heart pumping even after it has been removed from the body.

Andrew Richards, a Ph.D. student in mechanical engineering, designed the “dynamic heart system”, which “pumps fluid through a pig heart so that it functions in a very realistic way.”
The machine operates using pressurized saline solution, also allows researchers to film the interior workings of the pumping heart – enabling them to ascertain exactly which surgical technologies and techniques perform best for repairing heart valves.
