About

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..

Full 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.

Enrollment: 18 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• patients over 18 years of age.
• arrhythmic storm refractory to conventional treatment.

Exclusion criteria

• patients younger than 18 years of age.
• previous history of heart transplantation.
• history of previous surgical cardiac sympathetic denervation.
• patients with neck anatomy considered unsuitable for the procedure (including previous neck surgery, burns, the presence of extensive scars, or large goiters with significant displacement of adjacent structures).
• contraindications to the interventional technique (such as infection at the puncture site, or refusal to provide consent).

Trial design
