A 64-year-old man manifested a stroke two years after restoration of sinus rhythm through a radiofrequency catheter ablation. Transesophageal echocardiography demonstrated the presence of a thrombus in the left atrial appendage. Left atrial volumes and different parameters of atrial emptying showed that, despite the persistence of the sinus rhythm, atrial mechanical function was severely impaired. After atrial ablation procedures echocardiography can be useful to stratify patients according to their risk of developing embolic events and hence be of help in deciding whether or not discontinuation of anticoagulant therapy is the appropriate choice.
一名64岁男性在通过射频导管消融恢复窦性心律两年后发生中风。经食管超声心动图显示左心耳存在血栓。左心房容积和心房排空的不同参数表明，尽管窦性心律持续存在，但心房机械功能严重受损。心房消融术后，超声心动图有助于根据患者发生栓塞事件的风险进行分层，从而有助于决定是否停止抗凝治疗是合适的选择。
