Coronary Artery Occlusion During Radiofrequency Ablation in a 2-Year-Old Boy.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundRadiofrequency ablation is an electrophysiological procedure for treating various forms of atrial and ventricular arrhythmias. One of its rare complications is coronary artery injury, with an incidence of <0.1%. CASE SUMMARY: A 2-year-old boy with atrial tachyarrhythmia underwent radiofrequency ablation using an irrigated tip catheter for a focus in the coronary sinus ostium as a result of incessant tachycardia not responding to medical therapy. During ablation, ST-segment elevation was observed in the inferior leads (II, III, aVF). Right and left coronary angiography was performed immediately, revealing an obstruction in the posterolateral branch of the right coronary artery. After diagnosis, balloon dilatation without stent was performed, and complete restoration of blood flow with TIMI flow grade 3 was achieved. DISCUSSION: We present a pediatric case with coronary artery occlusion during radiofrequency ablation. Immediate diagnosis and management played a vital role in resolving the occlusion and restoring the blood flow.
