VATS cardiac sympathetic denervation for ventricular arrhythmias: initial experience in a tertiary care centre.
Article in Indian journal of thoracic and cardiovascular surgery, 2022. 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
Cardiac sympathetic denervation (CSD) is a useful therapeutic option for patients with ventricular arrhythmias (VAs) refractory to anti-arrhythmic agents and/or catheter ablation. However, the experience is mostly limited to non-structural heart disease in paediatric patients. The advent of video-assisted thoracoscopic surgery (VATS) with its reduced morbidity has encouraged the use of VATS CSD in patients with structural heart disease. In this series, we report the surgical and cardiac outcomes of VATS-guided CSD in four patients who presented with electrical storm in the setting of different structural cardiomyopathies. Four patients underwent VATS-guided CSD at our centre during the period 2019-2021 after failure of conventional medical and/or ablative treatment for the management of refractory VAs. All four patients presented with electrical storm with different cardiomyopathies including ischaemic (post-acute myocardial infarction) and non-ischaemic aetiologies (sarcoidosis, non-specific right ventricular cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy). A combined total of 349 implantable cardioverter defibrillator (ICD) shocks were registered in the 4 weeks preceding the procedure with mean shocks of 87 per patient. All four patients successfully underwent CSD through the VATS approach with no operative mortality or any major surgical morbidity. All patients had resolution of electrical storms with 75% of patients remaining free of ICD shocks at a mean follow-up of 14.87 months. One patient who remained free of ICD shocks and recurrent VAs died at 23 months after the procedure due to progressive heart failure and complications. VATS CSD is a safe and effective complementary therapeutic modality in patients with life-threatening refractory VAs and electrical storms irrespective of the underlying substrate.
