title: Malfunction of a Bjork-Shiley prosthetic heart valve in the mitral position producing an abnormal echocardiographic pattern.
abstract: This report presents an echocardiographic study of a patient with fibrous ingrowth about the sewing ring and hinges of a Bjork-Shiley valve in the mitral position. The valve was obstructed and produced a distinct motion pattern. In addition to having a rounded diastolic motion, the disk excursion was decreased.
