Congenital heart disease is the most common birth defect among children in China. Approximately 20% of children with complex congenital heart disease may develop right ventricular outflow tract dysfunction after surgical repair, among which pulmonary artery stenosis is one of the most prevalent long⁃term postoperative complications. Percutaneous pulmonary artery stenting has emerged as a novel minimally invasive interventional approach, demonstrating favorable advantages in ameliorating congenital heart disease postoperative hemodynamic disturbances in pulmonary artery. With advancements in new type of devices, material engineering, and interventional techniques, percutaneous pulmonary artery stenting has achieved remarkable progress in both technology and application. This review summarizes the research progress on application of percutaneous pulmonary artery stenting for postoperative pulmonary artery stenosis in congenital heart disease, analyzing the challenges and opportunities of pulmonary artery stent in this field, aiming at providing new research directions for the treatment of right ventricular outflow tract dysfunction following congenital heart disease surgery.
