目的评估经食管超声下左心耳声学造影(contrast-enhanced of left atrial appendage,CE-LAA)与三维经食管超声(three dimensional transesophageal echocardiography,3D-TEE)技术对左心耳(left atrial appendage,LAA)内血栓的诊断价值...目的评估经食管超声下左心耳声学造影(contrast-enhanced of left atrial appendage,CE-LAA)与三维经食管超声(three dimensional transesophageal echocardiography,3D-TEE)技术对左心耳(left atrial appendage,LAA)内血栓的诊断价值。方法经胸超声或CT可疑左心耳血栓的心房颤动患者42例,均行CE-LAA及3D-TEE,以常规经食管超声(transesophageal echocardiography,TEE)检查为金标准,比较CE-LAA及3D-TEE对左心耳血栓的诊断价值。结果CE-LAA检测左心耳血栓的敏感性、特异性、阳性预测值、阴性预测值分别为100%、94.7%、95.8及100%,明显高于3D-TEE的88.5%、73.1%、76.7%及86.3%,差异有统计学意义(P<0.05)。结论同3D-TEE相比,CE-LAA对左心耳血栓的鉴别更具优势;CE-LAA能够为临床提供更准确信息,值得在临床上推广应用。展开更多
