Supplementary Material for: A Rare Case of Aortic Valve Myxoma: An Unusual Cause of Embolic Stroke

Aortic valve myxoma is an extremely rare cardiac tumour. We describe a 60-year-old woman found to have an aortic valve myxoma and a patent foramen ovale (PFO) presenting as a stroke. In view of the recurrent cerebral ischaemic events, the aortic valve myxoma was surgically removed and the PFO was closed. To the best of our knowledge, this is the first reported case of aortic valve myxoma with a PFO. We also highlight the importance of identifying a possible cardiac source of embolism in a stroke patient and considering this rare tumour as a cause in patients with a cryptogenic stroke.

主动脉瓣黏液瘤（aortic valve myxoma）是一种极为罕见的心脏肿瘤。本文报告1例以脑卒中为首发表现的60岁女性患者，经检查确诊其同时患有主动脉瓣黏液瘤及卵圆孔未闭（patent foramen ovale，PFO）。鉴于患者存在复发性脑缺血事件，临床遂行主动脉瓣黏液瘤切除术与卵圆孔未闭封堵术。据我们所知，这是首例报道的合并卵圆孔未闭的主动脉瓣黏液瘤病例。本研究同时强调，脑卒中患者需积极排查潜在的心源性栓塞来源，且对于隐源性脑卒中（cryptogenic stroke）患者，应将此种罕见肿瘤纳入病因鉴别范畴。
