Pulsed-Field Ablation for Incessant Atrial Tachycardia Originating From the Left Atrial Appendage Apex.
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
backgroundFocal atrial tachycardias (ATs) originating from the left atrial appendage (LAA) apex are rare and challenging to treat given the high risk of cardiac perforation with conventional radiofrequency ablation. CASE SUMMARY: A 15-year-old girl with an incessant AT arising from the LAA apex was successfully and safely treated using a novel contact force-sensing focal pulsed-field ablation (PFA) catheter with 10 applications. The patient remained asymptomatic, without tachycardia recurrence throughout a 4-month follow-up. DISCUSSION: This first report demonstrates the safety and efficiency of PFA for AT arising from the LAA apex. TAKE-HOME MESSAGES: For focal ATs originating from the LAA apex, a contact force-sensing focal PFA catheter is a viable alternative therapy. This approach enables targeted ablation of the arrhythmogenic focus while mitigating perforation risk, thus offering clinical utility for this challenging subset of focal ATs.
