Assessment of wall-shear stress pre and post renal sympathetic nerve denervation in patients with resistant hypertension

Background Renal denervation (RD) is a promising treatment for patients with resistant hypertension, with a good safety profile. Studies performed in animal models have demonstrated an increase in renal arteries’ velocity and flow. The hemodynamic effects of RD on renal arteries in humans remain unknown. The aim of our study is to evaluate the hemodynamic effect of RD on renal arteries non-invasively, using magnetic resonance (MR) techniques.
