An Artificial Heart That Beats Like the Real Thing

Is the Great Depression of 2008 giving you heart palpitations? Here’s some good news: France’s leading cardiac surgeon has unveiled an artificial heart that’s almost as good as a human’s. “If you show the graphs to a cardiac surgeon, he will say it’s a human heart,” Dr. Alain Carpentier said. “But no, it’s not a human heart, it’s the prosthesis.” After successful testing on calves and sheep, the device—which uses electronic sensors to regulate blood flow and heart rate—will be implanted in human patients within three years.
