The impact of left atrial voltage abnormality on ablation outcomes in paroxysmal atrial fibrillation and its pre-procedural predictors: an observational retrospective study.

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
backgroundLeft atrial (LA) localized voltage abnormality displayed by electro-anatomic mapping (EAM) has been established as a surrogate marker of atrial fibrosis (AF) which predicts post-ablation recurrence. This study investigates preoperative predictors of LA voltage abnormalities and assesses their impact on atrial fibrillation recurrence following catheter ablation in patients with paroxysmal atrial fibrillation (PAF).
resultsForty-four (25.6%) patients had LA voltage abnormality which independently predicted post-ablation recurrence (HR 2.85, 95%CI 1.20-6.78, p = 0.02). Larger left atrial diameter (LAD) (OR 1.24 per 1 mm, 95%CI 1.02-1.50, p = 0.03) and higher atrial tachyarrhythmia (ATA) burden (OR 1.02 per 1%, 95%CI 1.00-1.04, p = 0.03) independently correlates with LA voltage abnormality with an ideal combined diagnostic efficiency (AUC 0.80, sensitivity 79.3%, specificity 70.7%, 95% CI 0.70-0.89, p < 0.01).
conclusionsLA substrate abnormality, even moderate, is an independent risk factor for PAF post-ablation recurrence which can be predicted pre-procedure by LAD and ATA burden.
