Renal sympathetic denervation and ventricular arrhythmias: a case of electrical storm with multiple renal arteries

Sympathetic hyperactivity contributes significantly to the development of ventricular arrhythmias (VA)1. Catheter-based renal sympathetic denervation (RSD) has been demonstrated to reduce norepinephrine spillover and efferent muscle sympathetic nerve activity2. We report a case of a patient with electrical storm, contraindication of cardiac ablation and multiple renal arteries in whom RSD was carried out as an attempt to reduce episodes of ventricular tachycardia (VT).

A 62-year-old man with dilated cardiomyopathy presented with syncope and multiple VA episodes. Implantable cardioverter-defibrillator records showed 50 episodes of VT (cycle length varying from 345 to 430 ms), resulting in 85 ATPs and eight shocks within 48 hours. No reversible ...
