Pulse filed ablation for paroxysmal atrial fibrillation with Mitral and carvotricuspid isthmus dependent atrial flutter

Abstract

Abstract Pulsed field ablation(PFA) as an nonthermal ablative mechanism is proved to be effective and safe in clinical application. Up to now, PFA is only used for atrial fibrillation ablation in limited clinical trials. This article describes a case of paroxysmal atrial fibrillation in which mitral and carvotricuspid isthmus dependented atrial flutter was discovered incidentally during PFA operation and successfully ablated with PFA. This is the first medical record of PFA for atrial fibrillation combined with mitral isthmus atrial flutter, marking the promise of PFA in the treatment of other various kind of arrhythmia, including mitral isthmus related arrhythmia which was previously considered to be challenging in traditional ablation method.
