Abstract
Pulmonary artery denervation (PADN) can block local sympathetic nerve of pulmonary artery, reduce the hemodynamic parameters of pulmonary arterial hypertension(PAH), attenuate pulmonary vascular remodeling, right ventricular hypertrophy and fibrosis, thus improving cardiac function.Early basic experiment has determined the position of sympathetic nerve of pulmonary artery in pulmonary endarterium and confirmed the safety and effectiveness of PADN in the animal model of PAH.PADN may play a role by inhibiting execssive activation of the sympathetic nervous system and renin-angiotension-aldosterone system.PADN has been applied to adult clinical research, and has achieved a good clinical effect.On this basis, the possibility of applying PADN to children′s PAH is being explored preliminarily. Key words: Pulmonary arterial hypertension; Pulmonary artery denervation; Autonomic nerve; Child
