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

Background: Left atrial appendage is an unusual site of origin of atrial tachycardia and ablation used to be challenging due to fear of perforation and increased risk of thromboembolism. Case summary: A 14-year-old patient presented with frequent palpitations due to atrial tachycardia. Mapping confirmed origin of the atrial tachycardia to be the tip of the left atrial appendage. It was successfully treated with catheter ablation of the source using a linear-tip pulsed field ablation catheter. Discussion: Pulsed field ablation catheters are associated with less thermal damage to adjacent tissues, and linear tip design are suited for direct ablation of the source of atrial tachycardia of left atrial appendage origin. This can avoid the thromboembolism risk of electrical isolation of left atrial appendage and is less invasive than surgical ligation.
