心房颤动复律前经食管超声心动图检测左心房血栓的临床意义

目的 评价经食管超声心动图(TEE)在非瓣膜性心脏病心房颤动患者药物或电复律治疗中的作用。方法 43例心电图证实的非瓣膜性心脏病心房颤动患者接受抗血小板或抗凝治疗并在复律治疗前24～48h行经胸超声心动图和TEE检查。结果 TEE发现左心耳血栓2例和左心房自发声影3例，经抗凝或抗血小板治疗后39例接受复律治疗，其中31例药物复律(成功19例，失败12例)，8例接受电复律(成功6例，失败2例)。所有患者在治疗期间均无血栓栓塞性并发症。结论 心房颤动患者早期接受复律治疗前，TEE探测心房血栓可作为指导抗凝治疗、降低血栓栓塞风险的一项必要的常规检查。

Transesophageal echocardiographic detection of left atrial thrombus and spontaneaus echo contrast before cardioversion of atrial fibrillation

Objective To evaluate the role of transeso phageal echocardiography(TEE) before chemical or electric cardioversion for non-vulvular atrial fibrillation. Methods Forty-three patients, confirmed non-vulvular atrial fibrillation, undertook anticoagulation or anti-platelet therapy and transthoracic echocardiography and TEE less than 24-48 hours prior to cardioversion. Results Two thrombi in the left atrial appendage and three spontaneous echo contrasts in the left atrium were evidenced. After anticoagulation or anti-platelet therapy, 39 patients undertook cardioversion therapy. Among them,31 patients received drug cardioversion,success in 19,and failure in 12;8 patients received electric cardioversion,success in 6,and failure in 2. There were no thromboembolic events during the hospitalization. Conclusions TEE performed before cardioversion for atrial fibrillation is necessary to reduce the risks of thromboembolic events and to guide for anticoagulation therapy.
