RESUMO
The Duromedics bileaflet pyrolitic carbon mechanical prosthesis was introduced by Hemex in 1982 and subsequently acquired by Baxter. This communication documents a case of sudden leaflet fracture of a Duromedics mitral valve 48 months after implantation, which was managed successfully by replacement with a St. Jude Medical mechanical prosthesis. The patient presented in acute distress with paroxysmal atrial tachycardia and pulmonary edema. Transesophageal echocardiography was used to diagnose the leaflet fracture. The fracture had occurred transversely, with the fragments embolizing bilaterally to the iliofemoral arteries. These were removed at a subsequent operation. Cases of such fractures of the Duromedics prosthesis have been reported, with cavitation damage being the postulated mechanism.
