Key result
Renal artery denervation generally improves blood pressure in resistant hypertension despite conflicting trial data.
Why the study?
There have been conflicting data from different randomized controlled trials regarding the efficacy of renal artery denervation in managing resistant hypertension.
Does renal artery denervation improve blood pressure in patients with resistant hypertension?
Does renal artery denervation improve blood pressure in patients with resistant hypertension?
This review highlights that renal artery denervation is generally effective for improving blood pressure in resistant hypertension, noting recent FDA approvals for the ReCor Medical Paradise and Symplicity Spyral RDN systems.
Answers are grounded in this paper and cite their sources.
Conflicting RCT data on renal denervation warrant clinical caution; leaves open its role in resistant hypertension pending further trials.
PURPOSE OF REVIEW: This review article discusses the controversies, strengths, and limitations of the current literature on renal artery denervation in the management of resistant hypertension, as well as the future directions of this intervention. RECENT FINDINGS: There have been conflicting data from the different randomized control trials assessing the efficacy of renal artery denervation in the management of resistant hypertension. SUMMARY: Renal artery denervation is achieved by ablating the sympathetic nerves surrounding the renal arteries using endovascular ultrasound, radiofrequency, or alcohol. Our review article highlights that renal artery denervation is generally effective in improving blood pressure in patients with resistant hypertension. The Food and Drug Administration (FDA) has recently approved the ReCor Medical Paradise system, and the Symplicity Spyral RDN systems for renal artery denervation.
