Assessment of incomplete lesions using 3-dimensional mapping following pentaspline pulsed field ablation for atrial fibrillation.
Article in Heart rhythm O2, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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: Pulsed field ablation (PFA) is a novel nonthermal modality for pulmonary vein isolation (PVI) in atrial fibrillation (AF). However, the completeness of lesion formation following PFA using a pentaspline catheter remains insufficiently studied. Objective: This study aimed to evaluate the utility of 3-dimensional (3D) electroanatomical mapping in detecting incomplete lesion formation following pentaspline PFA in patients with AF. Methods: This study included 100 consecutive patients undergoing first-time PFA with the FARAWAVE™ catheter (Boston Scientific) under fluoroscopic guidance. 50 patients with paroxysmal AF underwent PVI alone, whereas 50 with persistent AF received PVI plus posterior wall isolation (PWI). Post-ablation 3D mapping was performed using the CARTO 3 system (Biosense Webster). Incomplete lesions were defined as preserved electrical activity or conduction gaps on activation or electrogram mapping. Results: Incomplete lesions were identified in 8 of 50 patients (16%) undergoing PVI alone and 24 of 50 patients (48%) undergoing PVI plus PWI ( Conclusion: 3D electroanatomical mapping effectively identifies incomplete lesions following pentaspline PFA. Detection rates were unaffected by operator learning curve, instead reflecting limitations of conventional guidance based primarily on fluoroscopy in patients with anatomical variability.
