Left atrial posterior volume and posterior-anterior volume ratio as predictive factors for atrial fibrillation recurrence: Insights from regional atrial remodeling

Heart RhythmPublished Retrospective cohort

Authors' conclusion

LA-P volume and PAVR are significant predictors of AF recurrence, underscoring the importance of regional atrial volumetric assessments to refine risk stratification and inform personalized treatment strategies for patients undergoing AF ablation.
