Brief Summary
Study design: Investigator initiated, single centre, feasibility study Main objectives are twofold:
- 1.To investigate the feasibility of RNS in patients with therapy resistant hypertension, which is assessing the functional distribution of renal nerves using 3D imaging and differential pacing modalities.
- 2.To investigate the blood pressure responses and cardiac excitable properties to RNS, and subsequently perform a RDN procedure, guided by 3D mapping by two different techniques e.g. RNS-checked RDN and RNS-guided RDN procedures.

Outcome Measures
Primary Outcomes (1)
arterial blood pressure response
Main study parameter will be the arterial blood pressure response to RNS prior to renal denervation and absence of blood pressure rise in response to pacing in the renal artery after RDN.

blood pressure at 3 months
3 months after the intervention
blood pressure at 6 months
6 months after the intervention
blood pressure at 12 months
