Abstract

Refractory ventricular tachycardia is a life-threatening condition. Therapeutic modalities for patients with ventricular tachyarrhythmias include atrioventricular nodal (AV) nodal blockade agents, anti-arrhythmics and radiofrequency catheter ablation. Sudden cardiac death associated with ventricular arrhythmias can be prevented with an implantable cardioverter-defibrillator (ICD) but the management of ventricular storm unresponsive to medical therapy remains a significant clinical challenge. A novel therapeutic approach involving sympathectomy via ultrasound (US) guided left sided stellate ganglion blockade has emerged with variable success rates. We describe five patients with ventricular arrhythmia refractory to medical management who underwent stellate ganglion block and report associated outcomes.
