BACKGROUND
Treatment of recurring atrial flutter can be challenging due to anatomical obstacles preventing complete conduction block of linear ablation lesions. Epicardial or bipolar ablation can be used as an alternative to create deeper ablation lesions but is still limitedly used in patients with atrial flutter.
CASE SUMMARY
We describe a case of a 54-year-old patient with recurring peri-mitral flutter treated with ablation of an anteroseptal line using bipolar ablation to achieve a complete conduction block.
DISCUSSION
As conventional ablation cannot always achieve, complete conduction block in linear ablation lesions alternatives may be used to create deeper lesions. In this, case bipolar ablation was used successfully for an anteroseptal line in a patient with recurring peri-mitral flutter.
背景
由于解剖学障碍妨碍线性消融病灶的完全传导阻滞，复发性心房扑动的治疗可能具有挑战性。心外膜或双极消融可作为一种替代方法来产生更深的消融病灶，但在心房扑动患者中的应用仍然有限。
病例摘要
我们描述了一例54岁复发性二尖瓣周围扑动患者，采用双极消融对前间隔线进行消融以实现完全传导阻滞的病例。
讨论
由于传统消融不能总是实现线性消融病灶的完全传导阻滞，可使用替代方法来产生更深的病灶。在本病例中，双极消融成功用于一名复发性二尖瓣周围扑动患者的前间隔线。
