title: [A successfully operated case of isolated tricuspid insufficiency due to traumatic laceration of anterior leaflet of tricuspid valve].
abstract: A case of isolated traumatic tricuspid insufficiency is presented. The patient was a 26-year-old designer with chief complaints of palpitation and dyspnea on exertion, who had the traffic accident three years and four months ago. The cardiac catheterization and two-dimensional echocardiography showed isolated insufficiency, and revealed that the basic damage was laceration of anterior leaflet of tricuspid valve itself. Tricuspid valve was replaced with SJM M-31 valve. His postoperative course was satisfactory. Until present to our knowledge, 13 cases of traumatic tricuspid insufficiency have been reported in Japan including our case. In three instances the papillary muscles ruptured. In nine patients the chordae tendineae were torn and in this case, there was primary laceration of anterior leaflet.
