Objective  To explore the application value of high-fidelity simulators in the clinical teaching of transthoracic echocardiography (TTE).

Methods  Residents receiving standardized training who rotated in the Department of Ultrasound Medicine, Zhongnan Hospital of Wuhan University, from November 2023 to November 2024, were selected as the research objects and divided into an experimental group and a control group. Both groups received theoretical and practical skill video learning of 10 key sections of TTE. The experimental group received practical training using high-fidelity simulators, while the control group received training through the traditional mode. After training, the training effects of the two groups were compared through assessment scores and questionnaires.

Results  A total of 24 residents were included, with 12 in each group. Before training, there was no statistically significant difference in the theoretical assessment scores between the two groups (P>0.05). After training, the experimental group achieved better results in the practical skills exam than the control group (82.08±5.03 vs. 71.83±0.83), and the difference was statistically significant (P<0.05). The residents in the experimental group generally held a positive attitude towards the practicality, simulation effect and teaching effect of the high-fidelity simulators.

Conclusion  The high-fidelity simulation teaching method can effectively improve the TTE examination skills of the residents and can be used as a beneficial supplement to traditional teaching.
