Renal Denervation

Renal sympathetic denervation (RSDN), or renal denervation (RDN), is a minimally invasive, endovascular catheter based procedure using radiofrequency ablation or ultrasound ablation aimed at treating resistant hypertension (high blood pressure not controlled by medication). Catheter-based interventional strategies that interrupt the renal sympathetic nervous system have shown promising results in providing better blood pressure control in patients with resistant hypertension.
