NCT02496117

Brief Summary

Study design: Investigator initiated, single centre, feasibility study Main objectives are twofold:

  1. 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. 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.

    during procedure

Secondary Outcomes (4)

  • 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

    12 months after the intervention

  • change in blood pressure compared to measurement before the intervention

    intervention - up to 12 months after the intervention

Study Arms (2)

RNS-checked RDN

ACTIVE COMPARATOR

20 patients with hypertension will be enrolled undergoing RNS-checked RDN

Procedure: Electrical mapping, nerve stimulation checked renal denervation procedure

RNS-guided RDN

EXPERIMENTAL

20 patients with hypertension will be enrolled undergoing RNS-guided RDN

Procedure: Electrial mapping, nerve stimulation guided renal denervation procedure
