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.
Article in Current cardiology reviews, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionEchocardiographic 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.
methodsBetween 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.
resultsParticipants 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.
conclusionThe 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.
