Background: To evaluate the effect of minimally invasive direct coronary artery bypass (MIDCAB) simulator for cardiac residency training.
Methods: A total of 26 resident surgeons who had never trained for coronary artery anastomosis participated in this training program. They received coronary artery anastomosis training on off-pump coronary artery bypass grafting (OPCAB) simulator for 15 h. After training, their performance of anastomosis was evaluated on the OPCAB simulator according to 12 items and a 5-point global rating scale. Based on the total score of assessment, those with an individual score of 12-36 formed group A, while group B was composed of the remaining trainees. The two groups then received another 15 h coronary artery anastomosis training on the MIDCAB simulator, and the performance was assessed.
Results: Trainees improved their performance of coronary artery anastomosis after training on the OPCAB simulator. Group A was composed of 7 trainees with an individual with a total score of 12–36 points and group B was composed of the remaining 19 trainees. After MIDCAB simulator training, significant differences were noted in the pre- and post-training values in the A group (P < .001), and the assessment value of group A was significantly better than those of group B (P < .05). No significant difference was detected between pre- and post-training values in group B after MIDCAB simulator training (P > .05).
Conclusion: We concluded that trainees who performed well in OPCAB simulation training can also perform better in MIDCAB, and our designed MIDCAB simulator was useful for residency training.
