Left Atrial Function and Strain Assessed by Three-Dimensional Echocardiography as Factors Associated With Atrial Fibrillation Recurrence After Pulmonary Vein Ablation.
Article in Journal of cardiovascular electrophysiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionRecurrence of atrial fibrillation (AF) after pulmonary vein isolation (PVI) remains a major clinical challenge. Left atrial (LA) remodeling contributes to recurrence, but its predictive value is still under investigation. This study aimed to assess LA morphology, function, and strain using three-dimensional (3D) echocardiography and determine their association with AF recurrence. METHODS AND
resultsThis prospective, single-center study included 119 patients with paroxysmal or persistent AF who underwent radiofrequency or cryoballoon ablation. Six months after the procedure, an echocardiographic assessment was performed, evaluating LA volumes, reservoir, conduit, booster pump function, global longitudinal strain (GLS), and LA ejection fraction (LAEF). AF recurrence occurred in 26.1% of patients. Patients with recurrence had larger LA dimensions (p < 0.01) and reduced GLS, LAEF, and peak atrial longitudinal strain (PALS) (p < 0.001). Multivariate analysis identified GLS > -13.5% (OR = 3.495, p < 0.001) and LAEF < 27.5% (OR = 0.857, p < 0.001) as independent predictors of recurrence. ROC analysis confirmed their strong discriminatory ability (AUC: 0.941 and 0.812, respectively).
conclusionLA remodeling and dysfunction are key predictors of AF recurrence after PVI. Reduced GLS and LAEF and increased LA size were independently associated with recurrence, supporting their role in risk stratification and personalized management. Incorporating 3D echocardiographic and strain-based analysis may enhance postablation surveillance and therapeutic decision-making.
