1 · What the graph read from it

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.

2 · The registry

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

backgroundRecent studies have confirmed the feasibility and safety of cavotricuspid isthmus (CTI) ablation using either a pentaspline or a focal monopolar pulsed-field ablation catheter. However, no documented cases have reported irreversible heart block as a potential complication. CASE SUMMARY: A 62-year-old woman with persistent atrial fibrillation underwent CTI ablation using a pentaspline pulsed-field catheter after pulmonary vein isolation. Immediately postablation, third-degree atrioventricular block occurred, transiently recovering to 2:1 block before reverting to complete heart block. A permanent pacemaker was subsequently implanted given irreversible conduction impairment. DISCUSSION: We report to our knowledge the first case of irreversible heart block after CTI ablation using a pentaspline pulsed-field ablation catheter, necessitating permanent pacemaker implantation after 13 hours of observation. This case underscores the need for caution when employing this technology for CTI ablation. TAKE-HOME MESSAGE: Irreversible heart block is a novel, albeit rare, complication of CTI ablation with a pentaspline pulsed-field catheter.
