[Abstract]Postoperativeconduction block is a critical complication in patients with Wolf-Parkinson-White syndrome（WPW）undergoing radiofrequency catheter ablation（RFCA），potentially resulting in permanent pacemaker implantation.To enhance procedural safety and improve patients’prognosis，，a profound understanding of its mechanisms and precise risk prediction are vitally important. This paper reviews the mechanismsand risk prediction of conduction block after RFCA in WPW patients.It systematically analyzes contributing factors for postoperative conduction block，including the anatomical site characteristics of abnormal atrioventricular accesory pathways，ablation-energy-induced injury，and intraoperative procedure-related risks.Byintegrating existing evidences，this paper aims to provide clinicians with a more comprehensive risk assssment framework and preventive strategies to guide individualized surgical planning，minimize the risk of conduction block，and thereby improve clinical outcomes.
