摘要
目的探讨经食道超声(transesophageal echocardiography,TEE)对射频消融术前房颤患者左房及左心耳血栓的诊断价值。方法对52例房颤拟行射频消融术患者同时进行经胸超声(transthoracic echocardiography,TTE)和经食道超声检查,比较分析左房和左心耳血栓检出情况。结果 52例房颤患者经胸超声检出左房血栓4例(7.69%),左心耳血栓3例(5.77%),其中1例假阳性,左心房自发显影(spontaneous echo contras,SEC)2例(3.85%);经食道超声检出左房血栓8例(15.38%),左心耳血栓9例(17.31%),左心房SEC 8例(15.38%),左心耳SEC 6例(11.54%),两种方法比较均有显著差异性。超声图像显示:左心房及左心耳内可见异常回声团块,附着于心房或心耳内壁,形态不规则,不活动,提示为左房或左心耳血栓形成,左房或左心耳内漩涡状或云雾状回声为血流自发显影现象,提示血流高凝状态。结论经食道超声明显提高了左房及左心耳血栓的检出率,是房颤射频消融治疗前的有效检查手段。
Objective To explore the diagnostic value of transesophageal echocardiography （TEE） in the left atrial and left atrial appendage thrombus before atrial ifbrillation radiofreguency ablation treatment.Methods 52 cases of patients with atrial fibrillation received check of transthoracic echocardiography （TTE）and TEE, before radiofreguency ablation treatment, the situation of left atrial and left atrial appendage thrombus were summarized.Results In 52cases patients with TTE, left atrial thrombus were found in 4 case（7.69%）, left atrial appendage thrombus in 3 case （5.77%）, The false positive in 1of 3 cases, left atrial spontaneous echo contras （SEC）in 2 case （3.85%）; In 52cases patients with TEE, left atrial thrombus were found in 8 cases （15.38%）, left atrial appendage thrombus in 9（17.31%）, left atrial SEC in 8（15.38%）, left atrial appendage SEC in 6（11.54%）.Every indice had statistically significantly in all patients between TEE and TTE.The Uitrasonic image of left atrial or left atrial appendage thrombus showed abnormal clumps echo attached to the wall. Swirling or cloudy signs which were explored in left atrium or left atrial appendage were SEC, It is hypercoagulable state. Conclusion The detection rate of left atrial and left arterial appendage thrombus is increasesed by TEE. It is a effective method before atrial ifbrillation radiofreguency ablation treatment.
