Radiofrequency catheter ablation of ectopic foci that trigger atrial fibrillation has been established as a curative method for patients with symptomatic paroxysmal atrial fibrillation. Although the majority of these foci are located in and around the pulmonary veins, other less common locations have been identified. Recognition that foci can lie outside the pulmonary veins is important for ensuring therapeutic success. The most frequently reported foci of ectopic activity outside the pulmonary veins are in the superior vena cava and the posterior wall of the left atrium. Here we report our experience with the ablation of ectopic foci located in the superior vena cava in patients with symptomatic paroxysmal atrial fibrillation.
射频导管消融触发房颤的异位灶已成为有症状阵发性房颤患者的一种治愈性方法。尽管这些病灶大多位于肺静脉及其周围，但也已确定了其他一些不太常见的位置。认识到病灶可能位于肺静脉之外对于确保治疗成功很重要。肺静脉外最常报告的异位活动病灶位于上腔静脉和左心房后壁。在此，我们报告了对有症状阵发性房颤患者位于上腔静脉的异位灶进行消融的经验。
