A NOVEL APPROACH TO TEACHING CORONARY ANGIOGRAPHY USING 3D-PRINTING

ABSTRACT

Background: Coronary angiography (CAG) is a fundamental component of cardiology fellowship. As the impact of COVID-19 fueled the need for self-directed and remote learning, we sought to develop a resource that would address this need and improve angiogram interpretation skills among fellows. To this aim we developed a teaching tool correlating fluoroscopic projections with a 3D-printed physical and digital model of coronary anatomy derived from coronary CT. We hypothesized that fellows exposed to this resource would benefit from improved comprehension of spatial concepts in CAG compared to usual resources. Methods: Twenty-two cardiology fellows were randomly assigned to exposure of the teaching tool versus usual resources. An exam assessing comprehension of the spatial orientation of coronary anatomy, aortic cusps, and catheter tip position in relation to fluoroscopic views was administered before and after a six-week exposure period. Scores were compared, and qualitative feedback was obtained using the Likert scale. Results: Fellows exposed to the content achieved a greater improvement on their exam score and were more likely to improve (Figure). All fellows felt the content was superior to existing resources and will improve their comprehension of CAG. Conclusion: Educational platforms leveraging 3D printing can enhance comprehension of CAG among cardiology fellows, and may serve as valuable resources to promote self-directed and remote learning.
