摘要

研究目的介绍门诊阶段心房颤动患者左心房阑尾血栓存在的超声心动图情况。本研究涉及塔吉克斯坦共和国 "希福巴赫什 "国立医疗中心 2019 年至 2022 年期间门诊的 56 名永久性心房颤动患者。所有患者均采用标准方法接受了经食道超声心动图检查。根据经食道超声心动图检查结果,所有患者(n=56)被分为两组:第一组--42 例(75%)左心房阑尾无血栓形成;第二组--14 例(25%)存在血栓形成。左心房阑尾血栓形成患者血栓栓塞、出血风险高,左心房扩大,血流速度峰值水平低。同时,与无血栓形成的亚组相比,血栓形成患者的自发回声对比现象平均高出 22%。我们的数据显示,在对心房颤动患者进行经食道超声心动图检查时,血流峰值速度和自发回声对比度可作为左房阑尾血栓形成的预测指标。

Echocardiographic picture of left atrial appendage thrombi in patients with atrial fibrillation
Aim. To present the echocardiographic picture of the presence of thrombi in the left atrial appendage in patients with atrial fibrillation in the outpatient stage.Material and research methods. The study involved 56 patients with permanent atrial fibrillation, observed in outpatient conditions at the National Medical Center of the Republic of Tajikistan “Shifobakhsh” between 2019 and 2022. All patients underwent transesophageal echocardiography using standard methodology.Research results. According to the results of transesophageal echocardiography, all patients (n=56) were divided into two groups: Group I - 42 (75%) with no thrombosis in the left atrial appendage; Group II - 14 (25%) with the presence of a thrombosis. Patients with thrombosis of the left atrial appendage had a high degree of thromboembolic, hemorrhagic risk, left atrial enlargement and a low level of peak blood flow velocity. At the same time, the phenomenon of spontaneous echo contrast in patients with thrombosis was on average 22% higher compared to the subgroup without thrombosis.Conclusions. Our data showed that during transesophageal echocardiography in patients with atrial fibrillation, peak blood flow velocity and spontaneous echo contrast can be taken as predictors of thrombosis of the left atrial appendage.
