Effectiveness of ultrasonography-guided cardiac sympathetic denervation in acute control of electrical storm: A retrospective case series.

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
Background and Aims: Ultrasonography-guided left cardiac sympathetic denervation (LCSD) or bilateral cardiac sympathetic denervation (BCSD) may be a useful intervention in the electrical storm (ES) that persists despite pharmacological therapy. The aim of our study was to evaluate the effectiveness of ultrasonography-guided LCSD or BCSD in the acute control of ES. We conducted a retrospective case series of patients who underwent ultrasonography-guided CSD for control of ES at a tertiary care hospital. Material and Methods: Data of all patients who underwent unilateral or bilateral CSD were collected from January 2017 to December 2019. Eleven patients with ES refractory to standard antiarrhythmic therapy underwent ultrasonography-guided pharmacological CSD (eight underwent LCSD and three underwent BCSD). Quantitative data was expressed as mean and median with interquartile range (IQR). Non-quantitative data was expressed in proportions. Results: Eleven patients underwent ultrasonography-guided pharmacological CSD (eight underwent LCSD and three underwent BCSD). Six of the eleven patients were female (54.5%). Ischemia was the underlying substrate in nine patients (81.8%). Five patients (46%) had complete resolution of ventricular tachycardia (VT) after CSD and one had 90% reduction in episodes of VT. The median follow-up duration was 8 months inter-quartile range IQR (7-18). One patient succumbed to heart failure and one patient was lost to follow up. The other patients had no further events and were well at last follow up. Conclusion: Ultrasonography-guided pharmacological CSD is effective in the acute control of ES. It is easily performed with equipment that is readily available and relatively safe in terms of immediate complications and is an ideal second-line intervention when ES persists despite drug therapy.
