Paroxysmal Atrial Fibrillation
Renal Denervation
Cardiac Ablation
Device: Renal Artery Ablation Catheter
Device: Cardiac Ablation

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment

Primary Outcome Measures:
  • Freedom from atrial fibrillation in patients with hypertension [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Major adverse cardiac events [ Time Frame: 7 days, 6 months, and 12 months post procedure ] [ Designated as safety issue: Yes ]
  • Percent of patients who experience a procedural related event [ Time Frame: 30 days post procedure ] [ Designated as safety issue: Yes ]
  • Assessment of renovascular safety as measured by new renal artery stenosis or aneurysm at the site of ablation [ Time Frame: 6 months, 12 months ] [ Designated as safety issue: Yes ]
  • Renal function change based on eGFR (renal denervation group only) [ Time Frame: 6 months,12 months ] [ Designated as safety issue: Yes ]
  • Recurrence of AF based on electrocardiographic data up to 2 years following the initial cardiac ablation procedure. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Percentage of subjects achieving office Systolic Blood Pressure < 140 [ Time Frame: 6 months post procedure ] [ Designated as safety issue: No ]
  • Change in Office and Ambulatory Blood Pressure parameters [ Time Frame: 6 month, 12 month, 24 month post procedure ] [ Designated as safety issue: No ]
