Enhanced Echocardiographic Assessment of the Aortic Root Structure: A Comparative Study of the Application of CT-3D Printing and Traditional Methods in the Teaching Context

Introduction: Echocardiographic assessment of the aortic root structure is critical with regard to efforts to diagnose and manage aortic valve diseases. However, traditional teaching methods often fail to provide the necessary depth and practical experience for residents. This study addresses this knowledge gap by exploring the value of applying computed tomography 3-dimensional (CT-3D) printing in the context of teaching echocardiographic assessment of the aortic root structure. Methods: Between January 1, 2022, and November 30, 2024, thirty residents in the Ultrasound Department of our hospital were recruited and randomly divided into a 3D printing group and a traditional teaching group. Participants in the 3D printing group used CT-3D printed aortic root models, whereas those in the traditional teaching group relied on standard methods. The theoretical knowledge and operational skills of participants in both groups were evaluated. Results: Participants in the two groups did not differ significantly in terms of their theoretical knowledge. However, participants in the 3D printing group outperformed those in the traditional teaching group in terms of their operational skills; the 3D printing group also exhibited higher levels of teaching effectiveness satisfaction (all P<0.05). Discussion: Our results revealed that the use of CT-3D printed models can result in improved operational skills and increased teaching satisfaction, echoing the findings reported by other studies that have revealed enhanced learning outcomes as a result of the integration of 3D printing into medical education Conclusion: The use of CT-3D printed models significantly improved operational skill training and teaching satisfaction in the context of education in the echocardiographic assessment of the aortic root structure.
