Radiofrequency Ablation and Right Purkinje De-Networking for Moderator Band PVC-Induced VF: Broadening the Therapeutic Landscape.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIdiopathic ventricular fibrillation (VF) can occasionally be triggered by rare premature ventricular complexes (PVCs), including those from the moderator band. Radiofrequency ablation (RFA) is challenging given low PVC burden and anatomic complexity. CASE SUMMARY: A 36-year-old man with idiopathic VF and an implantable cardioverter-defibrillator for secondary prevention presented with multiple shocks. The VF episodes were triggered by short-coupled PVCs from the moderator band. Despite a low PVC burden (<1%), zero-fluoroscopy catheter ablation was performed. RFA was guided by pace mapping, followed by right-sided Purkinje de-networking. The procedure was uncomplicated, and at 8-month follow-up, the patient remained asymptomatic, with no PVCs or arrhythmic events. DISCUSSION: Low-burden PVC-triggered VF is challenging, as conventional pace mapping is limited. Targeted Purkinje network ablation (de-networking) appears to reduce the risk of recurrent VF. TAKE-HOME-MESSAGE: Pace-mapped RFA combined with ipsilateral Purkinje de-networking may be an effective zero-fluoroscopy strategy for PVC-induced VF, even with low ectopic burden.
