Bipolar catheter ablation of a left atrial anteroseptal line in a patient with peri-mitral atrial flutter: a case report

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.
