Although M-mode echocardiography (MME) is not a reliable method for detecting left atrial thrombi, recent reports suggest that two-dimensional echo (2DE) may be more effective than MME in identifying intracardiac thrombi. In three patients with prosthetic mitral valves who presented with either arterial embolization or prosthetic valvular dysfunction, 2DE demonstrated left atrial masses consistent with thrombi, while MME was either negative (two patients) or suspicious (one patient) for left atrial thrombus. Thrombi were documented by surgical or postmortem examination in all cases. Clear delineation of the atrial cavity and the margins of the masses, visualization on multiple echocardiographic views and comparison of serial examinations were helpful in identifying these masses as thrombi. In addition, the masses visualized had certain patterns of motion which seem unique and may allow characterization of atrial masses as thrombi.
虽然M型超声心动图（MME）并非检测左心房血栓的可靠方法，但近期报告表明，二维超声（2DE）在识别心内血栓方面可能比MME更有效。在3例出现动脉栓塞或人工瓣膜功能障碍的人工二尖瓣患者中，2DE显示左心房有与血栓相符的团块，而MME对左心房血栓的检查结果要么为阴性（2例患者），要么可疑（1例患者）。所有病例的血栓均通过手术或尸检得到证实。心房腔和团块边缘的清晰勾勒、多个超声心动图视图上的可视化以及系列检查的比较，有助于将这些团块识别为血栓。此外，可视化的团块具有某些独特的运动模式，这可能有助于将心房团块定性为血栓。
