Renal denervation (RDN) is a recent procedure that can be used to control BP (blood pressure) in hypertensive patients. Numerous publications from randomised trials have demonstrated the efficacy of RDN in this indication. The latest guidelines now include RDN as an effective technique for use in hypertension. Since early 2023, RDN using Medtronic's Spiral radiofrequency system has benefited from transitional authorisation for reimbursement by the French health insurance system. An application for reimbursement is underway for the ultrasound system. We aim to compile an exhaustive prospective register of all procedures carried out in France over the next few years, regardless of the type of catheter used or the context in which the procedure was carried out (transitional reimbursement, industrial register, randomised trial). Our aim is to assess the efficacy and safety of the procedure within the French healthcare system, the characteristics of patients benefiting from the procedure, the centres performing renal denervation, and the care pathways used, and to be able to present all this data, independently of the industry, to the healthcare authorities when it comes time to reassess the value of this procedure and its indications. The goal of this observational study is to learn about changes in blood pressure in patient with high blood pressure before and 1 year after a renal denervation treatment (RDN). The primary endpoint is to describe changes in systolic blood pressure (SBP) measured by Home Blood Pressure Measurement (HBPM) in patients suffering from high blood pressure, before and 1 year after RDN.
This study concerns patients with high blood pressure who have been treated with renal denervation since January 2010 or who will undergo renal denervation after March 2025.
