Summary

The objective of our study was to evaluate the effectiveness of stellate ganglion block (SGB) and of the bilateral cardiac sympathetic denervation (BCSD) in patients with electrical storm refractory to conventional treatment..

Detailed description

A prospective, single-center observational study was designed with the aim of evaluate the safety and short-term efficacy of SGB within the first 24 hours, as well as the long-term effectiveness of ultrasound-guided percutaneous BCSD at 12 months, in patients with refractory electrical storm.

Conditions

• Ventricular Arrhythmias
• Electrical Storm
• Stellate Ganglion Block

Interventions

Type	Name	Description
PROCEDURE	Cardiac sympathetic denervation.	Patients underwent stellate ganglion block with 10 ml of levobupivacaine 0.25% and subsequently ultrasound-guided percutaneous bilateral cardiac sympathetic denervation , two neuroablative lesions were created using conventional radiofrequency treatment at 60°C, 20 V for 90 seconds.
