Simulator training is important for teaching perfusion students fundamental skills associated with CBP before they start working in the clinic. Currently available high-fidelity simulators lack anatomic features that would help students visually understand the connection between hemodynamic parameters and anatomic structure. Therefore, a 3D-printed silicone cardiovascular system was developed at our institution. The aim of this study was to determine whether using this anatomic perfusion simulator instead of a traditional “bucket” simulator would better improve perfusion students’ understanding of cannulation sites, blood flow, and anatomy. Sixteen students were tested to establish their baseline knowledge. They were randomly divided into 2 groups to witness a simulated bypass pump run on 1 of 2 simulators—anatomic or bucket—then retested. To better analyze the data, we defined ‘true learning’ as characterized by an incorrect answer on the pre-simulation assessment being corrected on the post-simulation assessment. The group that witnessed the simulated pump run on the anatomic simulator showed a larger increase in mean test score, more instances of true learning, and a larger gain in the acuity confidence interval. Despite the small sample size, the results suggest that the anatomic simulator is a valuable instrument for teaching new perfusion students.
