目的：实践操作外科培训课程使用三维(3D)打印的心脏模型来模拟复杂的先天性心脏手术。本研究旨在验证模拟Norwood手术2种技术的模型和评估工具，并调查在有Proctor在场和没有Proctor在场的情况下排练后技术表现是否有所改善。方法：在3D打印的左心发育不全综合征模型上，5名有经验的外科医生和5名初级外科医生进行了Norwood手术的2种技术。对10名在先天性心脏病手术(CHS)(医学博士学位与非医学博士学位)不同经验的评分员的表现进行了回顾评估。使用专门的手术操作培训-CHS工具进行评估。分析了结果的技术表现和评分者的一致性。经过验证，30名外科医生(24名有Proctor指导，6名只有培训视频和客观反馈)模拟了Norwood手术两次。结果：有经验的外科医生和评分员在有经验的外科医生和初级外科医生之间有明显的区别(P
OBJECTIVES: The hands-on surgical training course utilizes 3-dimensional (3D)-printed heart models to simulate complex congenital heart operations. This study aimed to validate a model and assessment tool in the simulation of 2 techniques of the Norwood operation and investigate whether technical performance improves following rehearsal with or without proctor presence.METHODS: Five 'experienced' and 5 'junior' surgeons performed 2 techniques of the Norwood operation on 3D-printed models of hypoplastic left heart syndrome. Performances were retrospectively assessed by 10 raters with varying experience in congenital heart surgery (CHS) (Medical Doctorate versus non-Medical Doctorate). Assessments were made with the procedure-specific Hands-On Surgical Training-CHS tool. Results were analysed for technical performance and rater consistency. Following validation, 30 surgeons (24 with proctor guidance and 6 with training videos and objective feedback only) simulated the Norwood operation twice.RESULTS: Performance scores were consistently higher for experienced surgeons and raters discriminated clearly between the experienced and junior surgeons (P
