We report an unusual case of an adult who underwent a mitral valve replacement with concomitant excision of the left atrial myxoma and thrombus. Echocardiography showed the presence of a large "thrombus" within the left atrial appendage, body and atrial septum. There was difficulty in trying to distinguish between the atrial thrombus and myxoma due to their morphological similarities. At time of surgery, frozen section confirmed the atrial septal component of the thrombus to be an atrial myxoma and the atrial septum was excised to obtain a clear margin.

我们报告了一例不同寻常的成年患者，该患者在进行二尖瓣置换术的同时切除了左心房黏液瘤和血栓。超声心动图显示左心耳、心房体部和房间隔内存在一个大的“血栓”。由于心房血栓和黏液瘤在形态上相似，难以区分。手术时，冰冻切片证实血栓的房间隔部分为心房黏液瘤，遂切除房间隔以获得清晰切缘。
