| 摘 要： | 目的比较多层螺旋CT（MSCT）与经食管超声心动图（TEE）诊断房颤患者左心房／左心耳内血栓的准确性，同时探讨二者发生差别的可能原因。方法119名阵发性或持续性房颤患者于射频消融术前行16排增强螺旋CT（16CCT）及TEE检查，排除左心房／左心耳内血栓。结果16CCT发现3例患者存在左心耳血栓，而TEE则诊断7例患者存在左心耳血栓（其中2例患者与16CCT结果相符，另外5例患者，TEE诊断新鲜血栓形成者为3例，其余2例患者血栓位于左心耳入口靠近左上肺静脉处）。以经食管超声心动图为金标准，16排增强螺旋CT诊断左心房／左心耳内血栓的敏感性为28．6％，特异性为99．1％，阳性预测值及阴性预测值分别为66．7％和95．7％，Kappa值为38．8％。结论16CCT与TEE诊断左心房／左心耳内血栓的符合率较低。

| Abstract: | Objective To compare the efficiency of 16-slice contrast-enhanced computed tomography (16 CCT) with transesophageal echocardiography (TEE) for detection of thrombi in LA/LAA,and to discuss the causes for difference between these 2 techniques and advantages and shortages of these 2 techniques.Methods Altogether 119 patients (paroxysmal n=50,persistent n=69) were enrolled,each patient underwent 16 CCT and TEE for exclusion of thrombus in LA/LAA before radiofrequency ablation.Results Among them,3 patients were... |
