Successful treatment of atrial flutter post-radiofrequency ablation for atrial fibrillation following atrial septal defect occlusion: a case report of pulsed field ablation.

ABSTRACT:

Background

Atrial flutter (AFL) is a common arrhythmia following radiofrequency ablation (RFA) for atrial fibrillation (AF), with varying incidence depending on the ablation strategy. Patients with prior atrial septal defect (ASD) occlusion pose challenges for ablation, particularly when the lesions are located near the occluder. Pulsed field ablation (PFA) has emerged as a promising alternative to RFA for the treatment of AF or AFL; however, its use in patients with ASD occlusion remains unexplored.

Case summary

We present the case of a 46-year-old female with a history of ASD occlusion and subsequent RFA for AF. Despite the initial success, she developed symptomatic AFL 3 months post-procedure. Intracardiac echocardiography (ICE)-guided transseptal puncture guided by ICE r
