To investigate the efficacy of renal denervation (RDN) on the recurrence of ventricular arrhythmia (VA) in Asian patients with implantable cardioverter defibrillators (ICDs).Eight ICD patients with recurrent VA episodes underwent RDN using an off-the-shelf saline-irrigated catheter. The pre- and postprocedural VA episodes were counted via ICD interrogation. All patients underwent successful RDN without any complications related to radiofrequency catheter ablation. The median follow-up was 15 months (range 6-30), and the median VA episodes per month were significantly reduced from 3.17 (range 0.33-15.33) to 0.10 (range 0-5.83) after RDN (P < 0.05).RDN is an effective suppressor of VA in Asian patients with ICDs.
