Outcomes of Non-Paroxysmal AF Undergoing Ablation Guided by a Novel High-Density Panoramic Cycle-Length Mapping System.

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
backgroundCatheter ablation is a current therapeutic approach for atrial fibrillation (AF). However, the efficacy for non-paroxysmal AF remains suboptimal.
objectiveWe hypothesize that the novel panoramic cycle-length mapping (CLM) system can guide the pulmonary vein (PV) isolation and additional potential AF drivers.
methodsA total of 31 patients with non-paroxysmal AF referred for ablation guided by a new high-density panoramic CLM system were prospectively enrolled. We then retrospectively screened the patients with non-paroxysmal AF undergoing the conventional method during the contemporary period (conventional group). They were matched with a 1:2 ratio (31 patients in Group 1 receiving the CLM-guided approach, and 62 patients in Group 2 receiving the conventional method).
resultsDuring a mean follow-up of 23.2 months, patients in Group 1 had fewer recurrent atrial arrhythmias (p = 0.037), mainly driven by a reduction in recurrent AF. There was no difference in recurrent atrial tachycardia or atrial flutter. In multivariate analysis, the application of the CLM module was the only independent factor for recurrent atrial arrhythmias after RFCA of non-paroxysmal AF.
conclusionsIdentification of the potential drivers in non-paroxysmal AF is crucial. Compared to the conventional method, ablation guided by a new high-density CLM system might result in better outcomes for patients with non-paroxysmal AF.
