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

backgroundPulsed-field ablation (PFA) is a novel nonthermal modality for atrial fibrillation ablation. Takotsubo cardiomyopathy (TTC) is associated with autonomic dysregulation, but its relationship with PFA remains unclear. CASE SUMMARY: A 62-year-old man underwent redo PFA including pulmonary vein, posterior wall, and superior vena cava isolation. The procedure was uneventful. Three hours later, he developed bradycardia, QT prolongation, and ventricular arrhythmia with cardiac arrest. Coronary angiography excluded obstructive disease, and ventriculography demonstrated apical ballooning consistent with TTC. Mechanical circulatory support led to full recovery. DISCUSSION: This case suggests delayed-onset TTC after PFA, possibly related to autonomic imbalance rather than direct myocardial injury. TAKE-HOME MESSAGES: Delayed life-threatening complications may occur after PFA. Postprocedural monitoring and readiness for rapid hemodynamic support are essential.
