Özet

Electrical storm (ES) is not a rare clinical entity. Sympathetic hyperactivity may play critical role in development and continuation of ES. Some recent reports have demonstrated that catheter-based renal sympathetic denervation (RSD) may reduce sympathetic activation and have a potential role in reducing arrhythmic burden. A 46-year-old man was admitted to clinic with frequent implantable cardioverter defibrillator shocks and ES related to catecholaminergic polymorphic ventricular tachycardia (VT). Tachycardia was unresponsive to administration of beta-blockers, verapamil, and flecainide. Catheter ablation failed to suppress initial premature ventricular contractions. Based on aggravating effects of sympathetic system in clinical tachycardia, decision was made to perform RSD. After the procedure, sinus rhythm was achieved and no polymorphic VT was detected. Sustained monomorphic VT with right ventricular origin was successfully ablated via endocardial radiofrequency ablation. This new treatment modality may be a potential alternative method for patients in whom other ablative strategies have been unsuccessful.
