Persistent atrial fibrillation; It is time to regroup.

Area of Science:

• Cardiology
• Electrophysiology
• Cardiac Ablation

Background:

• Pulmonary vein isolation (PVI) is the established ablation strategy for both paroxysmal and persistent atrial fibrillation (AF).
• A significant challenge remains in managing persistent AF recurrence despite achieving durable PVI.

Observation:

• A subgroup of patients with persistent AF experience recurrence of the arrhythmia after PVI.
• Currently, no definitive, scientifically validated ablation strategy exists for these cases.

Findings:

• This article summarizes the clinical approach employed at Johns Hopkins Hospital for managing persistent AF recurrence post-PVI.
• The described strategy aims to provide a structured pathway for further interventional treatment.

Implications:

• This approach may guide clinicians in managing complex persistent AF cases.
• Further research is needed to establish evidence-based guidelines for repeat ablation in persistent AF after PVI.
