A patient with a thrombosed mechanical valve underwent valve re-replacement during which a tumor of the left ventricular outflow tract with the typical macroscopic and microscopic characteristics of a papillary fibroelastoma was successfully removed surgically. The 60-year-old woman had undergone isolated mitral valve replacement with a St Jude Medical 29-mm valve for mitral regurgitation 15 years ago. The present admission was for investigation of dyspnea on exertion. Two-dimensional transthoracic echocardiography demonstrated a posteroseptal, pedunculated mass, measuring 1.3x1.0 cm, in the outflow tract of the left ventricle, mild mitral regurgitation and slight aortic stenosis.
一名患有机械瓣血栓形成的患者接受了再次瓣膜置换手术，术中成功切除了左心室流出道的一个肿瘤，该肿瘤具有典型的乳头状纤维弹性瘤的宏观和微观特征。这位60岁女性15年前因二尖瓣反流接受了圣犹达医疗公司29毫米瓣膜的单纯二尖瓣置换术。此次入院是为了调查劳力性呼吸困难。经胸二维超声心动图显示左心室流出道有一个1.3×1.0厘米的后间隔带蒂肿块、轻度二尖瓣反流和轻度主动脉瓣狭窄。
