A case is reported in which the formation of a right atrial mass was detected by two-dimensional echocardiography 3 weeks after successful transvenous electrical ablation of the atrioventricular junction had been performed. The mass was attached to the atrial septum at the site where the electrode catheter used for the ablation had 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 thrombus formation must be considered as a potentially dangerous complication of transvenous catheter ablation to control supraventricular arrhythmias.
报道了1例病例，在成功进行房室交界区经静脉电消融术后3周，二维超声心动图检测到右心房肿块形成。该肿块附着于用于消融的电极导管所在部位的房间隔，且无活动度。其被解释为由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，但右心房血栓形成必须被视为经静脉导管消融控制室上性心律失常的一种潜在危险并发症。
