Trial Outcomes & Findings for REnal SympathetiC Denervation to sUpprEss Tachyarrhythmias in ICD Recipients (NCT NCT01747837)

NCT ID: NCT01747837

Last Updated: 2020-03-04

Results Overview

The primary endpoint of this study is the time to first event requiring implantable cardioverter defibrillator (ICD) therapy or Incessant VT. (Ventricular tachycardia (VT) occurring below the ICD rate cut-off); this will be assessed in the on-treatment patient cohort. An event requiring ICD therapy is defined as an anti-tachycardia pacing (ATP) or shock therapy for ventricular tachycardia or fibrillation.

Measure
Standard ICD Implantation Alone
These subjects will undergo standard ICD implantation alone (if not already present)
Boston Scientific Vessix Renal Denervation System
These subjects will undergo standard ICD implantation (if not already present) plus renal sympathetic denervation. Boston Scientific Vessix Renal Denervation System: Renal sympathetic denervation is modulation of the nerves which run along the renal arteries (the renal sympathetic nerves) with radiofrequency energy. This is the same energy source used to perform your heart ablation. Boston Scientific Vessix Renal Denervation System, Boston Scientific, Inc., Quincy, Massachusetts
