Renal denervation in the treatment of resistant hypertension

Abstract

Renal denervation is an invasive method of catheter-based radiofrequency ablation of the sympathetic nerves located around renal arteries. Results from the Symplicity HTN-1 and HTN-2 trials have demonstrated evidence that renal denervation can safely reduce blood pressure in patients with resistant hypertension.

More research is needed to verify these data, clarify unanswered questions and assess future applications of RSD. An overview of current and upcoming denervation devices is also included.
