ABSTRACT Background: Catheter-based radiofrequency renal denervation has emerged as a promising tool for blood pressure control in patients with resistant hypertension. The aim of the present study was to evaluate the feasibility and safety of percutaneous renal sympathetic denervation by radiofrequency ablation using an irrigated-tip catheter in patients with true resistant hypertension. Methods: A saline-irrigated catheter was used for renal sympathetic denervation. The sample consisted of a consecutive series of 11 patients with resistant hypertension based on office blood pressure […]
