Stellate Ganglion Blockade for Refractory Ventricular Arrhythmias: Implications of Ultrasound-Guided Technique and Review of the Evidence

Refractory ventricular arrhythmias (VAs) carry high mortality rates despite electrical and pharmacologic therapy utilization. These patients often require aggressive hemodynamic support, including mechanical circulatory devices such as extracorporeal membrane oxygenation because of progressive hemodynamic and metabolic deterioration. Sympathetic nervous system stimulation and neuronal remodeling after myocardial insults have been implicated as drivers of refractory VAs. This understanding has led to interest in and a growing body of experience with percutaneous blockade of the stellate ganglion as a means of interrupting the vicious cycle of refractory VAs.
