Pulsed-Field Ablation for Atrial Premature Complexes From the Right Atrial Appendage Apex: A Novel Application.
Article in JACC. Case reports, 2025. 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
backgroundAtrial premature complexes (APCs) refractory to medical therapy pose management challenges. Pulsed-field ablation (PFA) is established for atrial fibrillation but is unreported for focal APCs. CASE SUMMARY: A 67-year-old woman with hypertension and hypothyroidism presented with 6-year refractory APCs (35.7% burden). Initial radiofrequency ablation at the right atrial appendage (RAA) apex failed owing to safety concerns. Subsequent PFA eliminated the APCs after 8 applications. DISCUSSION: This first report demonstrates the efficacy of PFA for APCs originating from the RAA apex, avoiding the risks of thermal ablation in thin-walled structures. TAKE-HOME MESSAGES: PFA safely eliminates arrhythmias originating from the thin-walled RAA apex. This novel approach avoids thermal ablation risks in high-risk anatomical sites.
