| 目的 探讨实时三维经食管超声心动图（RT3D-TEE）测量左心耳排空流速（PEV）及三维容积变化率(3D-EF)在预测非瓣膜性房颤患者左心耳自发显影及血栓形成中的应用价值。方法 选取203例心房颤动患者，分为异常组及未见异常组，分别测量左心耳排空流速及三维容积变化率。结果 两组间左心耳排空流速及三维容积变化率有统计学差异，以3D-EF截断值38%预测左心耳自发显影或（和）血栓形成的灵敏性100%，特异度90.6%；以PEV截断值30.85cm/s预测左心耳自发显影或（和）血栓形成的灵敏性100%，特异度89%。结论 实时三维经食管超声心动图检查对预测左心耳自发显影或（和）血栓形成有重要的临床价值。 |

| Abstract: |
| Objective To investigate the value of transesophageal three-dimensional echocardiography (RT3D-TEE) in the measurement of left atrial appendage flow velocity (PEV) and the rateof three-dimensional volumetric change (3D-EF) in the prediction of spontaneous echo contrastand thrombosis of left atrial appendage in patients with nonvalvular atrial fibrillation. Methods A total of 203 patients with atrial fibrillation were selected and divided into the groups with abnormality and no abnormality. The left atrial appendage flow velocity and the rate of three-dimensional volumetric change were measured, respectively. Results There were significant differences in left atrial appendage flow velocity and the rate of three-dimensional volumetric change between the two groups. The sensitivity predicted by 38% of the 3D-EF cutoff value of the left atrial appendage spontaneous echo contrast or (and) thrombosis was 100%, and the specificity was 90.6%. The sensitivity predicted by30.85 cm/s of the PEV cutoff value of the left atrial appendage spontaneous echo contrast or (and) thrombosis was 100% and the specificity was 89%. Conclusion Real-time three-dimensional transesophageal echocardiography has important clinical value in predicting left atrial appendage spontaneous echo contrastor (and) thrombosis. |
