First Experience Using a Novel Variable Loop Catheter for Mapping and Pulsed Field Ablation of Atrial Fibrillation.
Review in Pacing and clinical electrophysiology : PACE, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND AND
aimsA novel multielectrode variable loop catheter (VLC) has been introduced for atrial fibrillation (AF) ablation enabling 3D electroanatomic mapping and concomitant pulsed field ablation (PFA). This study sought to investigate the VLC under routine clinical conditions for AF ablation.
methodsConsecutive patients with symptomatic AF undergoing first-time AF ablation were prospectively enrolled. All procedures were carried out using the VLC. Electroanatomic mapping pre and post-ablation was conducted with the VLC and a high-density multipolar mapping catheter. The general ablation protocol consisted of four ablation pulses per pulmonary vein (PV). All procedures were conducted in conscious sedation.
resultsForty-five patients (mean age 66.3 ± 6.1 years, 68.9% paroxysmal AF) were analyzed. Procedure duration was 66.3 ± 13.1 min. Acute pulmonary vein isolation (PVI) was achieved in 45 patients without periprocedural complications. Remapping after the initial 16 ablation pulses revealed sustained electrical conduction to at least one PV in six patients (13.3%). Repeat ablation was conducted and with an average of 7.5 ± 4.5 additional pulses. PV intubation during mapping was achieved in 168/180 PVs with the VLC (93.3%) and in 180/180PVs (100%) with the high-density mapping catheter (p < 0.001). Incomplete PV intubation during mapping did not result in incomplete PVI, as demonstrated by remapping utilizing the high-density mapping catheter. Adequate correlation between left atrial post-ablation remapping of low voltage areas and ablated regions was demonstrated in all patients.
conclusionPFA-guided AF ablation using the novel VLC is safe and effective. The integration into a 3D-electroanatomic mapping system enables adequate mapping during PFA procedures.
