Brief Summary:
The study is aiming to document the long-term safety and effectiveness of renal denervation in patients with hypertension and other diseases characterized by elevated sympathetic drive. Catheter-based renal denervation will be performed using CE marked, percutaneous, systems.

Condition or disease Intervention/treatment Phase
Hypertension Heart Failure Chronic Kidney Disease Diabetes Heart Rhythm Disorders Device: Renal denervation with Symplicity Flex Medtronic/Ardian Device: Renal denervation with EnligHTN St. Jude Medical Device: Renal denervation with Paradise Recor Device: Renal denervation with V2 Vessix Phase 1 Phase 2

Detailed Description:

Inclusion Criteria

  1. Individual is 18 years of age.
  2. Individual agrees to have all procedures performed, and is competent and willing to provide written, informed consent to participate in the registry.
  3. Patient scheduled for renal sympathetic denervation using market-released device.

Exclusion Criteria

  1. In the eyes of the treating physician, the renal artery anatomy would interfere with safe cannulation of the renal artery or meets local standards for surgical repair.
  2. Individual has any serious medical condition, which in the opinion of the treating physician may adversely affect the safety and/or effectiveness of the participant (i.e., patients with clinically significant peripheral vascular disease, abdominal aortic aneurysm, bleeding disorders such as thrombocytopenia, hemophilia, significant anemia, etc.).

Renal denervation using CE-marked devices will be performed according to best medical practice.

Device: Renal denervation with Paradise Recor
Renal denervation using CE-marked devices will be performed according to best medical practice.

Device: Renal denervation with V2 Vessix
Renal denervation using CE-marked devices will be performed according to best medical practice.
No Intervention: Medical therapy
Best medical therapy using guideline recommended drugs in each disease state.


Outcome Measures
Go to

Primary Outcome Measures :
  1. Safety and efficacy of renal denervation [ Time Frame: Baseline to 6 months ]

    Effect on blood pressure including office, ABPM, and home-based measurements.

    Number of adverse events (death, stroke, myocardial infarction, new dialysis, and congestive heart failure).

    Changes of antihypertensive medications.

    Effects on renal function assessed with glomerular filtration rate.

    Renovascular safety (renal artery stenosis) assessed by duplex ultrasound.



Secondary Outcome Measures :
  1. Effect of renal denervation on different organ systems. [ Time Frame: Baseline, 3, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 months ]

    Myocardial function and geometry using echo and MRI.

    Heart rate changes and arrhythmias.

    Glucose metabolism and insulin resistance (fasting and during oGTT).

    Hospitalization rates (eg. hypertensive emergencies, heart failure, etc).


  2. Safety and efficacy of renal denervation [ Time Frame: Baseline, 3, 12, 18, 24, 30, 36, 42, 48, 54, 60 months ]

    Effect on blood pressure including office, ABPM, and home-based measurements.

    Number of adverse events (death, stroke, myocardial infarction, new dialysis, and congestive heart failure).

    Changes of antihypertensive medications.

    Effects on renal function assessed with glomerular filtration rate.

    Renovascular safety (renal artery stenosis) assessed by duplex ultrasound.
