Ball-and-cage Heart Valve The heart’s four valves control blood flow through the heart with every beat. If damage or disease impair the valves, surgeons can replace them, most commonly the mitral and aortic valves on the heart’s left side. The Starr-Edwards valve was the first artificial mechanical valve used successfully in humans, and uses a ball-and-cage design to control the flow of blood. It was the product of a partnership between surgeon Dr Albert Starr, and engineer Mr Lowell Edwards. Me
