The authors studied 56 patients with cardioembolic stroke to search for intracardiac thrombi by use of transesophageal and transthoracic echocardiography. Forty consecutive patients were examined within four weeks of stroke onset and the remaining 16 in the chronic stage. They also performed ultrafast computed tomography in 9 of them. Underlying heart disease was present in all subjects. Anticoagulant therapy had already been started in 29 at the time of examinations. Using their own criteria for echocardiography, they diagnosed intracardiac thrombus in 7 cases and valvular vegetation in 1. Six thrombi were located in the left atrial appendage, 4 of which were smaller than 10 mm in diameter. These small thrombi were not found by either transthoracic echocardiography or computed tomography. Transesophageal echocardiography appears to be superior to the other two methods, especially for detecting small intracardiac thrombi in the left atrial appendage.
作者对56例心源性栓塞性中风患者进行了研究，通过经食管和经胸超声心动图来寻找心内血栓。连续40例患者在中风发作后4周内接受检查，其余16例处于慢性期。他们还对其中9例患者进行了超速计算机断层扫描。所有受试者均存在潜在的心脏病。在检查时，29例患者已经开始接受抗凝治疗。根据他们自己的超声心动图标准，他们诊断出7例心内血栓和1例瓣膜赘生物。6个血栓位于左心耳，其中4个直径小于10毫米。经胸超声心动图或计算机断层扫描均未发现这些小血栓。经食管超声心动图似乎优于其他两种方法，特别是对于检测左心耳内的小的心内血栓。
