Key result
Stellate ganglion block successfully controlled ventricular electrical storm in a patient following NSTEMI, allowing for safe completion of a subsequent radical nephrectomy.
Why the study?
Increased cardiac sympathetic activity after myocardial injury can cause ventricular electrical storm, and stellate ganglion block provides minimally invasive temporary sympathetic cessation to control it.
Does stellate ganglion block control ventricular electrical storm in a patient post-NSTEMI?

Does stellate ganglion block control ventricular electrical storm in a patient post-NSTEMI?
Stellate ganglion block may be a safe and effective minimally invasive option for controlling unstable ventricular electrical storm following myocardial infarction.
Stellate ganglion block may control post-NSTEMI electrical storm and permit surgery; hypothesis-generating, prospective trials needed.
If cardiac sympathetic activity increases after myocardial injury, a ventricular electrical storm (VES) may occur. The stellate ganglion block is a minimally invasive technique performed to control VES through temporary sympathetic cessation. This case was treated after 3 stellate ganglion blocks in VES developed after non-ST elevation myocardial infarction. This patient underwent prophylactic stellate ganglion block prior to radical nephrectomy for a renal mass found during hospitalization, and the operation was safely completed. Stellate ganglion block is expected to be a safe treatment option for patients with unstable VES.

Kwon et al. (2022) conducted a case report in Ventricular electrical storm (n=1). Stellate ganglion block was evaluated on Control of ventricular electrical storm and safe completion of surgery. Stellate ganglion block successfully controlled ventricular electrical storm in a patient following NSTEMI, allowing for safe completion of a subsequent radical nephrectomy.
