A 62-year-old female patient with known mitral-valve prolapse for the previous five
years presented with progressive dyspnea and intermittent palpitations. This clinical
presentation was investigated by two-dimensional echocardiography which revealed moderate
mitral regurgitation due to a pedunculated mass oscillating between the left atrium
and the left ventricle. Successful operative treatment consisted of en-bloc resection
of the tumor from the anterior mitral valve leaflet and its primary cords and subsequent
reconstruction of the mitral valve. Pathohistological examination revealed a cystic
lymphangioma originating from mitral-valve tissue. To our knowledge this is the first
reported case in the literature.
