Embolic Stroke After Pulsed Field Ablation for Atrial Fibrillation.
Article in JACC. Case reports, 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
backgroundPulsed field ablation (PFA) has rapidly gained adoption as a nonthermal ablation modality for atrial fibrillation. While considered safer regarding collateral tissue injury, ischemic stroke after PFA has recently emerged as a potential complication. CASE SUMMARY: We report 5 elderly patients (>75 years, high CHA DISCUSSION: These cases suggest that ischemic stroke after PFA is embolic in nature. Possible causes include air embolism introduced through the sheath or catheter, microbubble formation at the electrode, and given recent reports of temperature elevations at the electrode even during PFA, thrombus formation may also be a possible mechanism. TAKE-HOME MESSAGES: Ischemic stroke can occur after PFA despite its nonthermal mechanism. Multiple small infarcts suggest an embolic rather than an atherothrombotic etiology, which might be characteristic of cerebral infarctions associated with PFA. Further research is needed regarding ischemic stroke associated with PFA.
