Cardiac Sympathetic Denervation for Termination of Ventricular Tachycardia Storm: A Multidisciplinary Case.
Article in JACC. Case reports, 2026. 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
backgroundVentricular tachycardia (VT) storm is a life-threatening arrhythmic emergency. In recent years, autonomic neuromodulation has emerged as an adjunctive strategy beyond catheter ablation, antiarrhythmic drugs, and sedation. CASE SUMMARY: A 39-year-old man with dilated cardiomyopathy and recurrent VT storm despite implantable cardioverter-defibrillator implantation, multiple ablation procedures, and long-term amiodarone therapy was admitted with incessant VT. Combined endocardial-epicardial ablation failed to provide durable control. Refractory VT recurred postprocedure and was suppressed under deep sedation but recurred upon sedation weaning. Sequential left stellate ganglion blockage (LSGB) and bilateral thoracoscopic cardiac sympathetic denervation (CSD) successfully terminated the storm, providing arrhythmia-free survival for 1 year until recurrence, after which he ultimately underwent orthotopic heart transplantation. DISCUSSION: This case highlights the efficacy of CSD as a rescue therapy in refractory VT storm associated with structural heart disease. Suppression of VT using LSGB may predict a favorable response to CSD. TAKE-HOME MESSAGES: Autonomic neuromodulation, including CSD, is an adjunctive therapeutic approach for VT storm, offering sustained sympathetic suppression and VT control. Patients who demonstrate good VT suppression with LSGB, suggesting a predominant sympathetic contribution, may be favorable candidates for CSD.
