Key result
PFA restores sinus rhythm in a case of paroxysmal AF and concomitant CTI-dependent atrial flutter.
Why the study?
PFA has only been used for atrial fibrillation ablation in limited clinical trials, leaving its application for other arrhythmias such as mitral isthmus-dependent flutter unclear.
Case Report (n=1)
This case report provides the first evidence that pulsed field ablation can be successfully used to treat paroxysmal atrial fibrillation combined with mitral and carvotricuspid isthmus dependent atrial flutter.
May support PFA feasibility in combined AF and flutter; leaves open need for prospective validation before practice change.
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.

He et al. (2023) conducted a case report in Paroxysmal atrial fibrillation with mitral and carvotricuspid isthmus dependent atrial flutter (n=1). Pulsed field ablation (PFA) was evaluated on Restoration of sinus rhythm. Pulsed field ablation successfully restored sinus rhythm in a 76-year-old female with paroxysmal atrial fibrillation and concomitant mitral and carvotricuspid isthmus dependent atrial flutter.
