Efficacy and Safety of Radiofrequency Renal Denervation in Drug Resistant Hypertension
Study of Efficacy and Safety of Radiofrequency Sympathetic Renal Denervation for Treatment of Drug Resistant Hypertension

Single-center, single group study of the efficacy and safety of transcatheter renal denervation for treatment of patients with essential hypertension uncontrolled despite combined pharmacotherapy including 3 or more hypotensive drugs one of which is a diuretic. Bilateral transcatheter renal denervation will be performed on the top of existed pharmacotherapy. Change in blood pressure (BP), left ventricle (LV) mass, carotid artery thickness, renal artery blood flow and renal function, will be assessed at 6 and 12 months of follow-up.

Phase 2
Phase 3
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Hypertension
Procedure: Bilateral radiofrequency sympathetic renal denervation
Bilateral radiofrequency sympathetic renal denervation is performed as percutaneous transluminal radiofrequency (RF) ablation of neural pathways in the renal artery walls and surrounding tissue using standard equipment for RF ablation of cardiac electrical pathways
Other Names:
  • Transcatheter renal denervation
  • Percutaneous radiofrequency ablation of renal nerves
Experimental: Renal denervation
All eligible patients undergo bilateral radiofrequency sympathetic renal denervation using endocardial ablation system: after standard renal angiography using femoral access a small size endocardial ablation catheter (5-6 F, 4 mm electrode) is inserted into renal artery and 4-8 point ablations are performed consecutively from distal part to aorta with 3-4 mm step and 90 degrees rotation on the upper, lower, front and back aspects of the artery to get circumferential coverage, then the procedure is repeated on the other side.
Intervention: Procedure: Bilateral radiofrequency sympathetic renal denervation
