Study Description

Brief Summary:

This is a prospective, multi-center, single-arm, non-interventional and open-label registry. The purpose of the registry is to document the long-term safety and effectiveness of renal denervation in a real world patient population with hypertension GSR DEFINE is the continuation of the Global SYMPLICITY Registry and collectively will enroll approximately 5000 patients with hypertension who undergo the renal denervation procedure, from over 300 sites worldwide. Subjects included in GSR DEFINE will be followed for a minimum of 1 year and up to 5 years post-procedure. Patients with uncontrolled hypertension will be enrolled in accordance with the inclusion criteria specified in the protocol.

Condition or disease	Intervention/treatment
Hypertension	Device: Medtronic Renal Denervation System

Detailed Description:

This registry will collect data prospectively on patients that receive renal denervation and treatment will be applied according to the 'Intended Use' in the IFU. The treatment will be performed according to routine hospital practice and no additional tests are required specific to the registry. This registry will serve as a tool to collect clinical data in order to expand the knowledge base of safety, effectiveness and functionality of the Medtronic renal denervation system in a real world patient population.

The key measures collected for the patients will be inclusive of, but are not limited to, blood pressure measurements, change in medications, eGFR changes (based on the MDRD formula) and clinical data pertaining to hypertension .

The inclusion criteria for the registry includes:

• Age ≥ 18 years or minimum age as required by local regulations
• The patient is an acceptable candidate for renal denervation based upon the Instructions For Use for the Medtronic renal denervation system. The procedure must be performed with an initial use, market-released Medtronic renal denervation catheter.
• The patient or legal representative has been informed of the nature of the registry has consented to participate and authorized the collection and release of this medical information by signing a consent form ("Patient Informed Consent Form" or "Patient Data Release Authorization Form")

Study Design

• Study Type: Observational
• Estimated Enrollment: 5000 participants
• Observational Model: Case-Only
• Time Perspective: Prospective
• Official Title: Global SYMPLICITY Registry (GSR) Denervation Findings in Real World (DEFINE)
• Actual Study Start Date: February 2012
• Estimated Primary Completion Date: May 2024
• Estimated Study Completion Date: October 2027

Groups and Cohorts

Group/Cohort	Intervention/treatment
Renal Denervation Treatment; All patients treated with renal denervation procedure will be enrolled as part of this single arm registry	Device: Medtronic Renal Denervation System; The Symplicity renal denervation system is comprised of a single-use, disposable catheter and a reusable radiofrequency (RF) generator. The Symplicity renal denervation system has CE Marking for the intended use of delivering low-level radiofrequency energy through the wall of the renal artery to denervate the human kidney.
