34-year-old male with history of recurrent atrial fibrillation (AF) and mitral stenosis, status post radiofrequency ablation (RFA) and prosthetic mitral valve replacement two years earlier was admitted with prosthetic valve thrombosis for redo mitral valve surgery. During the surgery, a 2 x 1.5 x 1 cm mass was identified on the interatrial septum, attached to the edge of tricuspid valve's septal leaflet by a stalk. The mass was excised and histological evaluation revealed myxoma. It is accepted that myxomas can develop after cardiac trauma. It is known that RFA for AF increases the risk of thrombus or endocarditis in the atrium. Herein, we report a myxoma case where we think the heat energy caused by RFA might have triggered the development of the tumor.
一名34岁男性,有复发性心房颤动(AF)和二尖瓣狭窄病史,两年前接受了射频消融术(RFA)和人工二尖瓣置换术,因人工瓣膜血栓形成入院接受二尖瓣再次手术。手术期间,在房间隔发现一个2×1.5×1厘米的肿块,通过一个蒂附着于三尖瓣隔叶边缘。肿块被切除,组织学评估显示为黏液瘤。黏液瘤可在心脏创伤后发生,这是公认的。已知用于治疗AF的RFA会增加心房血栓或心内膜炎的风险。在此,我们报告一例黏液瘤病例,我们认为RFA产生的热能可能触发了肿瘤的发生。
