The prevalence, distribution and ablation of non-pulmonary vein triggers in older patients with paroxysmal atrial fibrillation.
Article in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo investigate the prevalence, distribution and ablation of non-pulmonary vein (PV) triggers in older patients with paroxysmal atrial fibrillation (AF).
methodsA total of 694 patients aged 65-80 receiving index ablation for paroxysmal AF were included. These patients were divided as follows: patients without low-voltage areas (LVA) (n = 437), LVA patients with modification (n = 175), and LVA patients without modification (n = 82). Following propensity score matching (PSM) analysis, two sets of matched groups emerged: LVA patients without modification (Group A, n = 77) and patients without LVA (Group B, n = 77), and patients without LVA (Group C, n = 168) and LVA patients with modification (Group D, n = 168). The clinical endpoint was defined as the detection of ATA lasting longer than 30 s through ECG documentation or Holter recordings following the index ablation.
resultsFifty-seven (8.2%) patients were identified with non-PV triggers, mostly originating from superior vena cava (SVC). Compared with Group A, Group B exhibited a higher prevalence of non-PV triggers (18.2% vs. 6.5%, p = 0.027). Likewise, Group C showed a higher prevalence compared with Group D (14.3% vs 7.1%, p = 0.034). Over a mean follow-up of 19.7 months, there was no significant difference in ATA recurrence between patients with non-PV triggers ablation (n = 57) and without non-PV triggers (n = 637) (71.9% vs 74.9%, p = 0.458).
conclusionsAmong older patients with paroxysmal AF, non-PV triggers exhibit a lower prevalence, originate mostly from SVC, and present less frequently in patients with LVA.
