Abstract：Objective To explore the application effect of 3 D printing technology in the standardized training of cardiovascular medicine specialists and provide new ideas for improving training quality.Methods A total of 40 cardiovascular medicine residents with no experience in surgical treatment of coronary heart disease or structural heart disease were selected from the First Affiliated Hospital of Nanjing Medical University from January to December 2024.They were randomly divided into an experimental group(20 residents,receiving theoretical lectures+3 D printing technology training)and a control group(20 residents,receiving only theoretical lectures).The teaching durations for both groups were the same.The teaching effect was evaluated through course assessments(diagnostic accuracy,standardized surgical operation procedures),teaching situation questionnaires(theoretical level,satisfaction with explanation,operation guidance level)and self-assessment questionnaires(learning ability,problem analyzing ability,etc.).SPSS 23.0 was used for statistical analysis.Results The score of standardized surgical operation procedures in the experimental group(42.15±3.00)was significantly higher than that in the control group(37.65±3.41,t=4.30,P<0.01),and there was a significant difference in diagnostic accuracy between the two groups(t=2.54,P=0.02).The score of the teaching situation questionnaire in the experimental group(53.35±1.65)was significantly higher than that in the control group(51.50±1.66,t=3.45,P<0.01).In the self-assessment questionaires,the scores of learning ability,problem analyzing ability and practical work ability in the experimental group were significantly higher than those in the control group(t=3.53,P<0.01;t=4.77,P<0.01;t=5.09,P<0.01,respectively),but there was no significant difference in the score of teamwork ability(t=0.82,P>0.05).Conclusion 3 D printing technology-assisted teaching can significantly improve standardized surgical operations,teaching satisfaction and core abilities(learning ability,problem analyzing ability and practical work ability)of cardiovascular medicine residents,providing an efficient new method for the standardized training of specialists.
