title: Fracture of the Carpentier-Edwards ring in tricuspid position: a report of three cases.
abstract: Three cases of fracture of a Carpentier-Edwards ring in tricuspid position are presented. In all three cases the shape of the ring was shown to be abnormal by roentgenogram examination; there was an abrupt bend in the middle portion of each ring. At the time of operation, fracture of the ring skeleton at this midpoint was found in all three instances. Roentgenogram examination seems to be a reliable method of diagnosing this uncommon entity, and tricuspid valve replacement is required for its correction.
