Impact of pulmonary vein isolation on atrial arrhythmias in patients with typical atrial flutter: systematic review and meta-analysis of randomized clinical trials.

ABSTRACT:

Aims

Cavotricuspid isthmus (CTI) ablation is the current ablation treatment for typical atrial flutter (AFL). However, post-ablation atrial tachyarrhythmias, mostly in the form of atrial fibrillation (AF), are frequently observed after CTI ablation. We aimed to evaluate the effectiveness and safety of concomitant or isolated pulmonary vein isolation (PVI) in patients with typical AFL scheduled for ablation.

Methods and results

Electronic databases (PubMED, EMBASE, Clinicaltrials.gov) were searched through July, 2024. Randomized controlled trials (RCTs) were eligible if comparing PVI ± CTI ablation vs. CTI alone. The primary outcomes were any sustained atrial arrhythmia, typical AFL relapse, and AF. Secondary outcomes were need for redo-ablation or antiarrhythmic drugs. Rando
