房颤患者双源CT重建在诊断左心耳血栓中的应用价值

Value of Dual-Source CT reconstruction in diagnosis of left atrial appendage thrombi with atrial fibrillation

目的探索双源CT重建对房颤患者左心耳血栓诊断的的价值。方法 35例患者分别接受左心耳双源CT重建及经食管超声心动图(TEE),对检测结果进行对比分析。结果与食管超声检出结果比较,左心耳双源CT重建符合率94.29%,诊断特异性为96.77%。灵敏度为80.0%,阳性预测值为83.33%,阴性预测值为96.77%。结论左心耳双源CT重建与TEE对房颤患者左心耳血栓的诊断有较好的一致性,能作为房颤患者左心耳血栓筛查和诊断的重要手段。

Objective To explore the value of Dual-Source CT in patients with atrial fibrillation diagnosis of left atrial appendage thrombi.Methods Totally 35 patients were treated with dual-source CT reconstruction of the left atrial appendage and transesophageal echocardiography（TEE）,the test results were analyzed.Results The detection result of the comparison with transesophageal echocardiography,left atrial appendage dual-source CT reconstruction in line with the rate of 94.29%,96.77% diagnostic specificity,sensitivity of 80.0%,the positive value of 83.33%,negative 96.77%.Conclusion Left atrial appendage dual-source CT in patients with atrial fibrillation and TEE LAA thrombus diagnosis have better consistency,it can serve as an important means of left atrial appendage in patients with atrial fibrillation screening and diagnosis of thrombosis.
