Summary

Despite significant advances in the management of ventricular arrhythmias through the use of ICD therapy, AADs, and catheter-based ablation strategies, considerable challenges remain. The optimal method for the prevention of recurrent VT following catheter ablation remains unclear. RSDN may be an effective tool for preventing ventricular arrhythmias, and associated ICD therapies, by reducing central sympathetic tone, catecholamine levels, and the renin-angiotensin- aldosterone system and promoting ventricular remodeling. Although RSDN has been shown to reduce the recurrence of VT in a case report of 2 patients suffering from electrical storm, to date no large prospective randomized study has evaluated the impact of RSDN in the prevention of recurrent VT in patients following catheter ablation of VT with ischemic or non-ischemic ventricular dysfunction. This study will specifically evaluate the safety and efficacy of adjunctive RSDN in the prevention of ICD therapy in patients with ischemic or non-ischemic ventricular dysfunction who are to receive a catheter-based VT ablation.

Conditions

  • Ventricular Tachycardia

Interventions

DEVICE

Renal sympathetic denervation

* The ablation catheter is placed within a long vascular sheath and advanced into the renal artery. The sheath is advanced over the catheter to engage the renal artery ostium and allow for contrast injection and visualization of the vessel during catheter manipulation. * After completion of the measurement, no more than six radiofrequency ablation lesions separated both longitudinally and rotationally (a "spiral pattern", see figure) will be placed per renal artery. The power will be started at 10 W and titrated to a maximum 20 W, as deemed appropriate by the impedance drop (goal 10% drop). Each lesion should be between 30-120 seconds in duration (no more than 120 seconds per lesion).

DEVICE

VT ablation alone

Placebo arm will receive standard VT ablation using current techniques
