Percutaneous Blockade of the Stellate Ganglion in Electrical Storm

Sponsor: University of Sao Paulo General Hospital

Summary

There is no randomized clinical study in the literature that evaluated the efficacy and safety of the stellate ganglion infiltration procedure in patients with electrical storm. So far, case reports and retrospective studies suggest that such a strategy should be considered in cases refractory to initial therapy. In this scenario, the European and American guidelines for the treatment of ventricular arrhythmias recommend autonomic modulation in this setting, but only with a level of recommendation IIb (1,2). This project aims to evaluate the effect of stellate ganglion infiltration in patients with electric storm refractory to initial clinical measures. It is a randomized clinical trial where patients will receive treatment with a lidocaine and bupivacaine anesthetic solution or no intervention. The effect of the intervention will be considered positive when there is a reduction of arrhythmic events of at least 50% in the 12 hours immediately after.
