Cardiac myxomas are rare with reported incidences of less than 0.03%. Cardiac myxomas are most commonly observed in the left atrium. Their clinical manifestations vary and most are non-specific to the diagnosis. The most common extra-cardiac manifestations are thrombo-embolic infarcts from tumor embolization. A previously healthy 55-year-old man presented with findings suggestive of acute arterial limb ischemia. Following surgical treatment of his acute presentation, a left atrial mass was found on echocardiography suggesting that the embolization was secondary to a cardiac myxoma. The patient was discharged without complication. Embolic myxoma should be included in the differential in younger, previously healthy patients presenting with acute arterial limb ischemia without obvious cause. Our patient's dramatic presentation with a single acute event, however, prompted immediate treatment and resulted in a functional recovery with minimal complications.
心脏黏液瘤很罕见，报告的发病率低于0.03%。心脏黏液瘤最常见于左心房。其临床表现各异，大多数对诊断不具有特异性。最常见的心脏外表现是肿瘤栓塞导致的血栓栓塞性梗死。一名55岁的既往健康男性出现提示急性肢体动脉缺血的症状。在对其急性症状进行手术治疗后，超声心动图发现左心房有肿块，提示栓塞继发于心脏黏液瘤。患者出院时无并发症。对于年轻、既往健康且出现无明显原因的急性肢体动脉缺血的患者，鉴别诊断应包括栓塞性黏液瘤。然而，我们的患者因单一急性事件而出现的显著症状促使立即进行治疗，并实现了功能恢复，并发症极少。
