The Beall-Cromie is a caged-disc mitral valve coated with Teflon. it is similar in design to Charles Hufnagel's caged disk valve. In this model, the ring is large and the cage is flimsy. It was designed by Dr. Arthur Beall (1929-2002) of Baylor University College of Medicine and Harry Cromie, an engineer who was involved in designing the sutureless Magovern-Cromie valve. Beall worked with Dr. Michael DeBakey during his residency at Baylor.
