[Myxoma of the mitral leaflet. Apropos of a case].
This case of an intracardiac myxoma observed in a 15 year old girl had several points of interest: the mode of presentation: the clinical signs were exclusively systemic and articular; the mode of diagnosis: 2D echocardiography demonstrated an immobile, dense mass about the size of a walnut implanted on the ventricular surface of the posterior mitral leaflet along the whole of its base and seemingly adherent to the ventricular wall; the intraventricular location of the tumour (exceptionally rare) and its mitral valve origin. The site of the tumour imposed mitral valve replacement but we were able to discuss the surgical approach using the results of echocardiography before surgery and a bioprosthesis was inserted to protect the maternal future of the patient.
