The authors report two operated cases of floating left atrial thrombus. Both patients had severe mitral stenosis, atrial fibrillation and dilatation of the left atrium. In the first case, the patient had no anticoagulant therapy; in the second case, the observance of anticoagulant therapy was irregular. Neither patient complained of syncope. The diagnosis was made in both cases by two-dimensional echocardiography which, in addition to confirming the severe mitral stenosis, showed a round, free-floating intra-atrial mass, rebounding from wall to wall and repeatedly engaging itself into the mitral orifice. The risk of prolonged engagement of the thrombus in the mitral orifice, causing syncope or sudden death, justifies urgent surgery associating thrombectomy and treatment of mitral stenosis every time this problem is encountered.
作者报告了两例左心房漂浮血栓的手术病例。两名患者均患有严重二尖瓣狭窄、心房颤动和左心房扩张。第一例患者未接受抗凝治疗；第二例患者抗凝治疗不规律。两名患者均未诉晕厥。两例均通过二维超声心动图确诊，该检查除证实严重二尖瓣狭窄外，还显示心房内有一个圆形、自由漂浮的肿块，在心房壁间反弹，并反复嵌入二尖瓣口。血栓长时间嵌顿于二尖瓣口导致晕厥或猝死的风险，说明每次遇到此问题时均应紧急行手术取栓并治疗二尖瓣狭窄。
