Focal Pulsed Field Ablation and Strategic Upsizing in Concomitant Atrial Fibrillation Ablation and Left Atrial Appendage Occlusion.
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
backgroundConcomitant atrial fibrillation ablation and left atrial appendage (LAA) occlusion are increasingly considered in patients with elevated thromboembolism and bleeding risk. Emerging data suggest a higher incidence of peridevice leak with pulsed field ablation (PFA). CASE SUMMARY: Two patients underwent concomitant PFA with the Sphere-9 catheter (Affera/Medtronic) and Watchman FLX Pro (Boston Scientific); postablation LAA changes were managed with tailored upsizing in one case and standard sizing in the other. At 6 months, both maintained sinus rhythm on antiplatelet therapy with no thromboembolic or bleeding events, and cardiac computed tomography confirmed well-seated devices with peridevice leak ≤2 mm. DISCUSSION: These are the first reported cases of concomitant LAA occlusion with Watchman FLX Pro and Sphere-9 PFA. Postablation LAA anatomical changes influenced device selection, and larger studies are needed to validate these findings. TAKE-HOME MESSAGES: Focal PFA led to specific, observable changes in LAA anatomy, directly affecting device sizing decisions. Tailoring device sizing to account for postablation LAA remodeling-using standard sizing or upsizing-may optimize device seal and compression.
