Is pulmonary vein antrum isolation a critical determinant of recurrent Arrhythmias after ablation of atrial fibrillation?

[摘要] In this issue of the journal, Di Biase et al. (1) reported their initial experience with remote magnetic navigation of a 4-mm-tip catheter for ablation of atrial fibrillation (AF). Their results confirm that the catheter navigated to targets and reduced fluoroscopy; however, the procedure time was not improved and the 4-mm-tip catheter was ineffective and prone to charring. This is why most groups have abandoned 4-mm-tip catheters for ablation of AF. Experience with remote navigation is required to assess tissue contact, but the incidence of charring reported by Di Blase et al.
