title: [A rare cause of obstruction of mitral valve prosthesis: periannular fibrosis. Diagnostic by transesophageal echocardiography].
abstract: The authors report a case of dysfunction of a double hemi-disc mitral valve prosthesis due to peri-annular fibrous overgrowth on the atrial side of the prosthesis. Conventional transthoracic Doppler echocardiography showed signs of thrombosis of the prosthesis. Transoesophageal echocardiography allowed a precise diagnosis of the lesions, resulting in immediate surgical referral.
