OBJECTIVES The aim of this study was to evaluate the impact of simulation-based training on surgical skills during 2-h learning labs during surgical annual meeting. METHODS During the 36th European Association of Cardiothoracic Surgery annual meeting a learning drylab for simulation-based training for endoscopic mitral valve repair was set up. For this purpose, a validated high-fidelity endoscopic mitral valve surgery simulator and a validated suturing map were used. The training lasted 2 h. Technical pre- and post-assessment were carried out based on time and accuracy to place a suture at the posterior mitral valve annulus. The suture had to be placed within 60 s. The suture was considered anatomically correct if it entered and exited the annulus at the designated place (on the posterior annulus) and accurate if placed within the right width (8–12 mm). RESULTS In total, 46 participants were included in this study, of whom 18 (38%) were experienced/staff surgeons, 23 (51%) fellows and 5 (11%) residents. Before the training, 48% of the participants failed to place any suture for pre-assessment. After completing the training, 100% of the participants succeeded in placing an anatomically correct suture. There was a significant improvement in the time taken [pre-assessment mean 45 (standard deviation: 25) s vs post-assessment mean 18 (standard deviation: 12) s, P < 0.001] and the accuracy to place a suture in the mitral valve annulus after completing the training (pre-assessment 32.6% vs post-assessment 65.2%, P < 0.001). CONCLUSIONS This study shows a significant improvement in endoscopic skills for mitral valve surgery after completing a 2-h training with a high-fidelity endoscopic mitral valve surgery simulator. This suggests that simulation trainings during scientific annual meetings are effective on surgical skills.
