It is now more than 5 years since I wrote my first commentary on renal denervation (RDN).1 At the time, I was prompted by the contrast between the enormous enthusiasm for the technique, inspired by dramatic claims of >30 mmHg reductions in systolic blood pressure (SBP) observed in patients with resistant hypertension who had undergone RDN,2–4 and the minimal falls in blood pressure (BP) when RDN was studied in well-controlled trials, particularly those involving sham-control procedures.5–7 National bodies and international guidelines followed,8,9 which recommended a moratorium on the widespread clinical uptake of RDN until such time as the true benefits or otherwise of RDN had been evaluated in well-controlled studies, in a variety of patient subgroups with hypertension and possibly other cardiovascular conditions, including heart failure. Two important studies now deserve further commentary. SPYRAL HTN-ON MED10 was a proof-of-concept randomised trial of BP lowering with the Symplicity Spyral multielectrode renal denervation catheter and the Symplicity G3 renal denervation RF generator (Medtronic), used to provide circumferential radiofrequency ablation treatments in a spiral pattern in the four quadrants of the renal artery and branch vessels. The control group received a sham procedure. A total of 467 patients were recruited into this trial, and subsequently 80 with uncontrolled BP (office SBP 150–180 mmHg, a 24-hour ambulatory SBP between 140 and 170 mmHg) and receiving one to three antihypertensive drugs were randomised to RDN or sham procedure. The primary efficacy end point was change from baseline ambulatory BP at 6 months. After 6 months, baseline-adjusted treatment differences between the RDN and sham control groups were −7.0/−4.3 mmHg for 24-hour ambulatory BP and −6.6/−4.2 mmHg for office BP in favour of RDN. Both results were statistically significant. No procedural or other adverse events were reported. In SPYRAL HTN-OFF MED,11 331 patients with an office SBP between 150 and 180 mmHg were randomly assigned RDN using the same procedure as for the ontreatment trial or sham control. The primary efficacy end point was baseline-adjusted change in 24-hour SBP at 3 months. The treatment differences between the two groups at 3 months in favour of RDN were 3.9 mmHg for 24-hour SBP and 6.5 mmHg for office SBP. Both differences were statistically significant. Again, no procedural or other adverse events were reported. Thus, after more than a decade, RDN comes of age.
