Pulsed-Field Ablation With Transcatheter Left Atrial Appendage Occlusion for Left Atrial Appendage-Origin Atrial Tachycardia.

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) may be an emerging treatment for left atrial appendage (LAA)-origin atrial tachycardia (AT), but it may cause thrombus in the LAA. Concomitant transcatheter LAA occlusion (LAAO) may address this risk. CASE SUMMARY: A 54-year-old man with symptomatic LAA-origin AT underwent PFA. Post-PFA transesophageal echocardiography showed significant pectinate muscle edema with narrowing of the LAA orifice. To avoid late peridevice leak, a 40-mm Watchman FLX Pro (Boston Scientific) was implanted with intentional overcompression. At the 1-month follow-up, cardiac computed tomography demonstrated a complete LAA seal with adequate device compression. DISCUSSION: Concomitant PFA and LAAO is feasible for LAA-origin AT. Because PFA can induce significant edema within the LAA, device selection based on pre-PFA imaging is critical to ensure durable sealing. TAKE-HOME MESSAGES: Careful pre-PFA imaging-based device sizing is critical when combining PFA with LAAO in patients with LAA-origin AT.
