A free-floating thrombus in the left atrium is very rare in mitral stenosis. Such a thrombus can lead to sudden circulatory arrest and syncope or can cause severe cerebral or peripheral thromboembolic events. Clinical diagnosis is difficult, but left atrial thrombus should be suspected if patients with mitral stenosis and atrial fibrillation have intermittent or changing murmurs, emboli, or syncope. We describe the case of a patient with mild mitral stenosis under warfarin therapy, and a left atrial pedunculated thrombus discovered during the investigation for syncope attacks.
左心房游离血栓在二尖瓣狭窄中非常罕见。这样的血栓可导致突然的循环骤停和晕厥，或引起严重的脑或外周血栓栓塞事件。临床诊断困难，但二尖瓣狭窄合并房颤的患者若出现间歇性或变化的杂音、栓塞或晕厥，则应怀疑左心房血栓。我们描述了一例接受华法林治疗的轻度二尖瓣狭窄患者的病例，该患者在对晕厥发作进行检查时发现了左心房带蒂血栓。
