Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this double-blind, randomized and sham controlled study is to investigate the blood pressure lowering effect of renal denervation by catheter based ablation in the renal arteries in patients with milder forms of treatment resistant hypertension. The effect on blood pressure will be evaluated by 24-hour ambulatory blood pressure measurements at baseline and after 3 and 6 months of follow up. Secondary endpoint evaluation comprises hemodynamic assessment by applanation tonometry and the cold pressor response.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Renal denervation by ablation of the renal arteries

By femoral access, renal angiography is performed. The patient will be sedated. In case of acceptable renal artery anatomy allowing renal ablation, the patient will be randomized in the cath. lab. If randomized to active treatment, renal artery ablation will be carried out straight away.

Group Type ACTIVE_COMPARATOR

Ablation of the renal arteries

Intervention Type PROCEDURE

Catheter-based renal denervation by applying low power radiofrequency to the renal artery using the EnligHTN Catheter, introduced by femoral artery access.

Control

By femoral access, renal angiography is performed. The patient will be sedated. In case of acceptable renal artery anatomy allowing renal ablation, the patient will be randomized in the cath. lab. If randomized to sham treatment, the procedure stops.

Group Type SHAM_COMPARATOR
