Objective　To compare the effects between the dual-cycle intensive training mode (DCITM) of teaching-in vitro-in vivo-summary-in vitro-in vivo-assessment and the single-cycle basic training mode (BTM) of teaching-in vitro-in vivo-assessment on training graduate students majoring in cardiovascular surgery. Methods　Eight graduate students majoring in cardiovascular surgery received the basic training of coronary artery bypass vascular anastomosis under the mode of BTM or DCITM. Then the training effects were evaluated by scoring of experts. Besides

SPSS 17.0 statistical software was used to analyze the evaluation results. Results　Compared with students who received BTM

the postgraduates trained by DCITM became more skilled in vascular anastomosis. In vitro

the average number of anastomosis completed by trainee increased significantly [(2.0±1.0) vs. (5.0±1.5)

P<0.05] over a specified period of time

the vascular leakage rate was significantly reduced [(92±5)% vs. (30±2)%

P<0.05]

and the average time per anastomosis was significantly shorter [in vitro: (20.1±2.5) min vs. (12.6±3.3) min

P<0.05]. There was also a statistically significant difference in the average time of each anastomosis in miniature pigs with coronary vascular anastomosis [in vivo: (30±2) min vs. (21±3) min

P<0.05]. Conclusion　Taken into together

DCITM is a highly efficient mode for promoting the quality of cardiovascular-surgery-teaching and enhancing the effectiveness of training in clinical surgical skills.
