Abstract
Tetralogy of Fallot is a common cyanotic congenital heart disease in children,often leading to symptoms such as cyanosis and hypoxic spell,squatting,heart murmurs,feeding difficulties in infants,and club-bing.Corrective surgery in infancy can alleviate the anatomical anomalies of tetralogy of Fallot.However,long-term postoperative complications may include pulmonary valve regurgitation,tricuspid valve regurgitation,resid-ual right ventricular outflow tract obstruction,aortic root dilation,arrhythmias,and right heart failure.Due to the pathological characteristics of tetralogy of Fallot(pulmonary valve dysplasia/stenosis and the use of transannu-lar patches),patients often coexist with postoperative pulmonary valve regurgitation and can survive asymptom-atically for a long time.This review primarily summarizes the current understanding of the pathological mecha-nisms and treatment progress of pulmonary valve regurgitation after Tetralogy of Fallot repair.It discusses the clinical examination methods for grading the severity of pulmonary valve regurgitation,surgical indications and timing,and analyzes the advantages and disadvantages of surgical pulmonary valve replacement versus percuta-neous pulmonary valve intervention,ultimately summarizing the better clinical treatment strategies to improve the quality of life for patients.关键词
