Pulmonary hypertension (PH), characterized by diverse etiologies and intricate pathological mechanisms, is a complex cardiopulmonary vascular disorder featuring high morbidity and mortality. Percutaneous pulmonary artery denervation (PADN) represents an emerging interventional treatment method, which shows good prospects in the clinical practice of PH. The PADN has attained preliminary achievements in terms of safety and efficacy. Nevertheless, its long-term prognosis, the characteristics of the appropriate patient populations, and the optimization strategies combined with targeted pharmacotherapy remain to be further explored. This article reviews the current clinical applications of PADN as well as the challenges it confronts.
