title: Fracture-embolization of duromedics valve prosthesis and microscopic uncommon lesions.
abstract: We report a sudden leaflet fracture of a Duromedics mitral valve 6 years after implantation. The patient had cardiogenic shock and complained of asthenia, orthopnea, and tachycardia. Transesophageal echocardiography showed the lack of one leaflet of the prosthesis and regurgitation. An emergency mitral replacement was successfully performed. Angiographic computed tomography scan localized the sequestrum that embolized the common iliac arteries. Examination of the deficient prosthesis showed multiple lesions and, in particular, a subsurface lesion that may be characteristic of carbon pyrolytic valves.
