Mitral Prolapse Caused by Lymphangioma

Abstract

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.

Key words
