Abstract

A 72-year-old woman was hospitalized with recurrent acute coronary syndrome after initial successful treatment of acute ST-elevation myocardial infarction with percutaneous coronary intervention. Echocardiography demonstrated unexpectedly a 9 x 8 mm pendulating structure attached to the anterior, proximal interventricular septum in the left ventricular outflow tract 6 mm beneath the aortic valve annulus. Magnetic resonance imaging of the heart yielded the same findings. The patient underwent coronary artery bypass grafting and tumour excision. The histopathological findings were typical for papillary fibroelastoma (PFE) with a central zone of connective tissue and some elastic fibres without blood vessels and covered by endocardium. PFE is the third most common type of primary cardiac tumours, second to myxoma and lipoma. PFEs are avascular papillomas that predominantly occur on the aortic and mitral valves (90%). However, the present case demonstrates that PFE occasionally can be attached to the ventricular wall endocardium.

摘要

一名72岁女性在经皮冠状动脉介入治疗成功初始治疗急性ST段抬高型心肌梗死后,因复发性急性冠状动脉综合征住院。超声心动图意外显示在主动脉瓣环下方6毫米处的左心室流出道前室间隔近端有一个9×8毫米的摆动结构。心脏磁共振成像也得到了相同的结果。患者接受了冠状动脉搭桥术和肿瘤切除术。组织病理学结果为典型的乳头状纤维弹性瘤(PFE),其中心为结缔组织区,有一些无血管的弹性纤维,表面被心内膜覆盖。PFE是第三常见的原发性心脏肿瘤类型,仅次于黏液瘤和脂肪瘤。PFE是无血管的乳头状瘤,主要发生在主动脉瓣和二尖瓣上(90%)。然而,本病例表明PFE偶尔也可附着于室壁心内膜。
