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) has emerged as a novel energy source for pulmonary vein isolation in atrial fibrillation. Although generally safe, rare complications may occur during catheter manipulation in challenging pulmonary veins. CASE SUMMARY: A 71-year-old man underwent PFA with a circular-array catheter for paroxysmal atrial fibrillation. Echocardiography showed preserved left ventricular systolic function and a left atrial diameter of 39 mm. The right inferior pulmonary vein (RIPV) measured 15 mm at the ostium but bifurcated immediately, complicating catheter advancement. During circular-array catheter manipulation in RIPV, oxygen desaturation occurred, requiring endotracheal intubation. Hemoptysis developed, and bronchoscopy revealed bleeding from the right-lower-lobe bronchus, suggesting RIPV perforation. Idarucizumab and protamine were administered, and contrast-enhanced computed tomography confirmed extravasation. Bleeding resolved with supportive care, and the patient was discharged after 13 days. DISCUSSION: This case highlights a rare but serious complication associated with challenging RIPV anatomy during PFA. TAKE-HOME MESSAGE: Careful manipulation of a guidewire and a circular-array catheter is essential in narrow, branching pulmonary vein to prevent vascular injury.
