What does this research mean for the field?

Pulmonary vein reconnections frequently occur at the anterior aspect after pulsed field ablation for atrial fibrillation, though a multiple procedure approach yields 86% arrhythmia-free survival and additional anterior lesions at the right pulmonary veins may reduce recurrences. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess the recurrence of atrial fibrillation (AF) after pulmonary vein (PV) ablation and identify factors influencing this recurrence.

Incidence and predictors of AF recurrence during long-term follow-up of patients after PF ablation for atrial fibrillation

Key Points

To assess the recurrence of atrial fibrillation (AF) after pulmonary vein (PV) ablation and identify factors influencing this recurrence.
Long-term follow-up of patients undergoing pulmonary vein ablation for atrial fibrillation.

Structured PICO

Do additional anterior lesions at the right pulmonary veins prevent AF recurrence in patients undergoing PF ablation for atrial fibrillation?

Population

Patients after pulsed field (PF) ablation for atrial fibrillation

Intervention

PF ablation with multiple procedure approach and/or additional anterior lesions at the right pulmonary veins (RPVs)

Outcome

AF recurrence / arrhythmia-free survival

A multiple procedure approach for PF ablation yields 86% arrhythmia-free survival, and additional anterior lesions at the right pulmonary veins may protect against recurrences.

Abstract

PV reconnections are frequent in patients presenting for repeat ablations, especially at the anterior PV aspect. A multiple procedure approach estimates arrhythmia-free survival in 86% of patients. Procedures with additional anterior lesions at the right pulmonary veins (RPVs) could be protective for recurrences.
