Currently, renal denervation (RDN) has proven its overall procedural and renal safety in registries and trials. Available data, suggest that vascular complications are rather scarce in modern studies using established neuromodulation catheters of different technologies and kidney parameters are mainly maintained stable overtime in RDN patients. Identification of the impact of energy delivery at vascular level by means of advanced methodologies such as optical coherence tomography (OCT) is a meaningful research tool. This accumulation of evidence on the acute and late effects of the procedure in the renal artery tissue especially when a new catheter is tested, as in the present work can further enhance our knowledge on the pathophysiology and clinical outcome of RDN.
