Painting of 3D Models of Congenital Heart Disease as an Educational Tool for Pediatric Residents

Background

Three-dimensional (3D) models of congenital heart diseases have been used to teach cardiac anatomy to learners. Our team sought to determine whether the painting of 3D models could help pediatric residents better understand both the anatomy and physiology of complex congenital heart diseases.

Methods

This was a prospective assessment of pediatric resident perceptions regarding a novel teaching method on the 3 stages of palliation for hypoplastic left heart syndrome. After attending a didactic session about the topic, they were provided with 3D models representing each stage. They were guided in painting them to represent the presumed oxygen saturations of each model’s chambers. Questionnaires were used to assess the self-perceived understanding of the anatomy, pathophysiology, and management from before to after the session using 5-point Likert scales. Statistical analysis was performed using a paired samples t test.

Results

There were 36 pediatric residents from 2 institutions. There was an increase in the mean self-perceived understanding of the anatomy (2.14 vs 3.94, P < 0.001), pathophysiology (2.14 vs 3.72, P < 0.001), and management of single ventricle palliation (2.19 vs 3.78, P < 0.001) before and after the session. All 36 participants enjoyed the session and wanted to participate in future sessions.

Conclusion

Painting of 3D models increased knowledge acquisition among pediatric residents.
