Objective:
Although simulation-based education is now commonly utilized in medicine, its use in the instruction of congenital heart disease remains limited. The objective of this study is to evaluate whether heart models created with three-dimensional printing technology can be effectively incorporated into a simulation-based congenital heart disease and critical care training curriculum for pediatric resident physicians.
Design:
Utilizing heart models created with a three-dimensional printer, pediatric residents participated in a 60-minute simulation seminar with three consecutive components: (1) didactic instruction on ventricular septal defect anatomy; (2) didactic/simulation-based instruction on echocardiographic imaging of ventricular septal defects and anatomical teaching/operative simulation of ventricular septal defect repair; (3) simulation-based instruction on postoperative critical care management of ventricular septal defects.
Setting:
Academic, free-standing, children's hospital with quaternary care referrals.
Participants:
Twenty-three pediatric resident physicians.
Outcome Measures:
Subjective, Likert-type questionnaires assessing knowledge acquisition, knowledge reporting, and structural conceptualization of ventricular septal defects.
Results:
Three-dimensional printing technology was successfully utilized to create heart models of five common ventricular septal defect subtypes. After using these models in a simulation-based curriculum, pediatric residents were found to have improvement in the areas of knowledge acquisition (P = .0082), knowledge reporting (P = .01), and structural conceptualization (P < .0001) of ventricular septal defects, as well as improvement in the ability to describe and manage postoperative complications in ventricular septal defect patients in the critical care setting.
Conclusions:
The utilization of three-dimensional printing in a simulation-based congenital heart disease and critical care training curriculum is feasible and improves pediatric resident physicians' understanding of a common congenital heart abnormality.
