A comprehensive analysis of 32 studies involving 9,194 patients found catheter ablation achieved a 65% arrhythmia-free rate at 12 months for persistent atrial fibrillation. Pulmonary vein isolation combined with additional ablation strategies showed numerically better outcomes (66%) compared to pulmonary vein isolation alone (63%). Pulsed field ablation demonstrated similar effectiveness to radiofrequency ablation (65% each) while showing lower complication rates. This meta-analysis addresses a critical knowledge gap in cardiovascular medicine, as persistent atrial fibrillation affects millions and significantly increases stroke risk and mortality. The finding that no single ablation approach consistently outperforms others suggests the field is moving toward personalized treatment selection based on individual patient factors. While the 65% success rate represents meaningful symptom control for many patients, it also highlights that roughly one-third still experience arrhythmia recurrence, underscoring the need for continued innovation. The low overall adverse event profile (1% for major complications) supports ablation as a viable option for appropriate candidates. However, as this is a preprint awaiting peer review, these findings require validation through the formal review process before informing clinical practice guidelines.
