Abstract: Renal denervation (RDN) as an interventional approach for treating refractory hypertension has developed a variety of ablation strategies and different energy ablation techniques. This article reviews the principles, characteristics, clinical advantages, and the latest research progress of mapping/selective RDN system. Selective RDN identifies “hot spots” (sympathetic nerve-rich points) through renal nerve stimulation (RNS) for targeted ablation, while avoiding “cold spots” (parasympathetic nerve-rich points) and “neutral points”, achieving more precise sympathetic nerve regulation. Animal experiments and clinical studies have shown that mapping/selective RDN can more effectively lower blood pressure, achieve blood pressure targets, and reduce the burden of antihypertensive drugs (reducing the drug index by 3.25). Mapping/selective RDN system provides a personalized solution for hypertension treatment, improving treatment efficiency and reducing complications.
