Study Overview
Brief Summary
The goal of this clinical trial is to learn if 3D-printed heart models and augmented reality can be useful modalities to teach medical students about congenital heart disease. The main questions it aims to answer are:
- Does using 3D-printed heart models improve learners' understanding of congenital heart disease when compared to traditional slide-based teaching methods?
- Does using augmented reality heart models improve learners' understanding of congenital heart disease when compared to traditional slide-based teaching methods?
- How can these modalities best be integrated into standard medical school curricula?
Participants will:
- Take a pre-test consisting of questions regarding anatomy and physiology of the normal heart as well as two congenital heart diseases.
- Be randomized into 3 groups that receive a teaching session using either slide-based lecture, 3D-printed models, or augmented reality.
- Take a post-test of the same questions from the pre-test.
- Take a delayed post-test of the same questions with additional subjective questions about their experience with their assigned modality.

Changes in Pre and Post-test Scores
Time Frame: Enrollment Pre-Intervention, Baseline Post-Intervention, and 3 Weeks Post-Intervention
Participants completed a 16-item, multiple choice questionnaire about the anatomy and physiology of the normal heart and two complex congenital heart defects. The questionnaire is broken down into 4 questions on basic cardiology and 6 questions each pertaining specifically to tetralogy of Fallot and hypoplastic left heart syndrome. The questionnaire is delivered pre-intervention, immediately post-intervention, and again at 3-weeks post intervention. Correct answers are scored as true (1) and incorrect answers scored as false (0) with a score range of 0-16 with higher scores indicating better retention and understanding of the curriculum.
