Lesion characteristics after pulsed-field ablation in patients with paroxysmal atrial fibrillation and a left common ostium (PFALCO RE-MAP 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
backgroundApproximately one-fifth of patients undergoing pulmonary vein isolation have a left common ostium (LCO). These patients tend to have worse arrhythmia-free survival when treated with a single-shot device, which may be related to lesion location and ablation thermodynamics. PURPOSE: This study evaluates lesion characteristics around the LCO in paroxysmal atrial fibrillation (AF) patients treated with a pentaspline pulsed-field ablation (PFA) modality.
methodsTwenty-two patients underwent PFA. Directly after the PFA applications, an electro-anatomical map (EAM) was created using the PFA catheter. After the procedure, three experienced operators were asked to draw a fictional ideal ablation line in the EAM encompassing the LCO. Outcome measurements were operators' satisfaction with the lesion characteristics and the distance from the lesion to the fictional ablation line.
resultsThe median age was 61 years [56-73] and the median CHA
conclusionsThe LCO lesion location after PFA in paroxysmal AF patients varies widely compared to the ideal ablation line. According to three experienced operators, unintended ablation and/or electrical activity were present in a substantial group of patients.
