Extrinsic obstruction of a Carbomedics prosthesis in the mitral position: echocardiographic and surgical findings.
In this article a case of malfunction of a Carbomedics mitral prosthesis in a patient with mild symptoms is described. Although there was evidence by echocardiography of a thrombus in proximity to the prosthesis and leaflet immobility assumed to be caused by the thrombus, it was demonstrated, at the time of surgery, that the immobility of the prosthetic leaflet was due to a chorda tendineae stuck between the leaflet and the sewing ring. This is the first report of this occurring in a bileaflet prosthesis. It is likely that the restricted mobility of the leaflet had contributed to the thrombosis of the prosthesis.
