Renal denervation for uncontrolled hypertension

  Figure 1:. Circumferential ablation of renal sympathetic nerves by (A) multielectrode radiofrequency ablation, (B) ultrasound-based denervation or (C) alcohol-mediated perivascular renal denervation. Radiofrequency treatment is delivered bilaterally in a number of locations along the main and extra-parenchymal renal arteries ranging from 3 to 8 mm in diameter. For ultrasound-based or alcohol-mediated denervation, treatment is applied to both main renal arteries only. Note: RDN = renal denervation. Kitty Choi

Example of a multidisciplinary, team-based care pathway for renal denervation *The clinical specialty of the hypertension experts and interventionalists will vary from centre to centre depending on clinical interests and local expertise.
