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

Intramural premature ventricular complexes (PVCs) are notoriously challenging during catheter ablation due to the depth of the arrhythmogenic substrate. We present a case utilizing intracardiac echocardiography (ICE) integrated with 3D electroanatomical mapping to ablate an intramural PVC in a patient with methamphetamine-associated cardiomyopathy. A 22-year-old female with a history of stimulant use disorder presented with debilitating palpitations and a 46% PVC burden. PVCs originating from the posterior superior process of the left ventricle (PSP-LV) were successfully targeted under ICE guidance. There were no arrhythmia recurrences during follow-up, highlighting ICE as an invaluable tool for mapping and ablating PSP-LV origin PVCs.
