Primary Outcome Measures:
  • Cardiovascular death or heart failure event [ Time Frame: Trial duration ]
  • Assess safety by evaluating all system or procedure-related complications [ Time Frame: Through six months post-implant ]

Secondary Outcome Measures:
  • To assess the timing and frequency of primary efficacy endpoint events. [ Time Frame: 24 months post-randomization ]
  • To assess changes in Left Ventricular Mass Index [ Time Frame: 6 months post-randomization ]
  • To assess changes in quality of life [ Time Frame: 6 months post-randomization ]

Enrollment: 19
Study Start Date: August 2009
Estimated Study Completion Date: April 2021
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Rheos Device
Rheos Baroreflex Activation System
Device: Rheos Baroreflex Activation System
Implant procedure
Other Name: Rheos System
Active Comparator: Medical Management
Medical Management Therapy
Other: Standard of care medical management
Patients will continue with medical therapy for standard of care of their heart failure condition.

Detailed Description:
This study closed to enrollment before adequate endpoint data was collected and before enrollment was completed. The study was not stopped for safety or futility, but for business/strategic reasons due to production of a new generation of the device. Currently, subjects are still enrolled in the trial under long-term follow-up.
