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 and gathering data for other diseases characterized by elevated sympathetic drive, such as diabetes mellitus type 2, renal insufficiency, etc. The Global Symplicity Registry will consecutively enroll 3000 patients who undergo the renal denervation procedure, from over 200 sites worldwide.

Condition or disease	Intervention/treatment
Hypertension; Diabetes Mellitus; Heart Failure; Chronic Kidney Disease; Sleep Apnea	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 and individual disease state(s) characterized by elevated sympathetic drive.

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: 3000 participants
• Observational Model: Case-Only
• Time Perspective: Prospective
• Official Title: Global proSpective registrY for syMPathetic renaL denervatIon in seleCted IndicatIons Through 3 Years Registry
• Study Start Date: February 2012
• Estimated Primary Completion Date: February 2022
• Estimated Study Completion Date: October 2023

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.

Outcome Measures

Primary Outcome Measures :

1. BP Measurements [ Time Frame: 6 months ]
   Blood pressure changes from baseline (Office Setting and 24-hr Ambulatory measurements)

Eligibility Criteria

• Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No
• Sampling Method: Non-Probability Sample

Study Population

Subjects undergoing renal denervation procedure to treat the diseases affected by increased sympathetic activity.

Criteria

Inclusion Criteria:

• 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")
