The formation of a right atrial mass was detected in a patient by two-dimensional echocardiography 3 weeks after successful transvenous electrical ablation of the atrioventricular node had been performed. The mass was attached to the atrial septum at the site where the electrode catheter used for the ablation had supposedly been located and it exhibited no mobility. It was interpreted as a right atrial thrombus induced by the ablation procedure. Although no pulmonary embolic events have been observed during a 7 month follow-up period, right atrial thromboembolism must be considered a potentially dangerous complication of transvenous catheter ablation to control cardiac arrhythmias.
在成功进行经静脉房室结电消融术后3周，通过二维超声心动图在一名患者中检测到右心房肿块。该肿块附着于据推测用于消融的电极导管所在部位的房间隔，且无活动度。它被解释为消融手术诱发的右心房血栓。尽管在7个月的随访期内未观察到肺栓塞事件，但右心房血栓栓塞必须被视为经静脉导管消融控制心律失常的一种潜在危险并发症。
