Background Despite data supporting the use of simulation training in procedural specialties and accreditation requirements, few options exist for electrophysiology (EP) training. We aimed to develop a low‐cost, accessible simulator for training in EP mapping, and to test the simulator in a group of novice users. Methods Our mapping simulator is composed of three components: an acrylic case representing torso and thigh; three‐dimensional (3D) printed cardiac models; and a commercially available mapping system. Using a proprietary flexible material that mimics the consistency of human heart tissue, we created an anatomically accurate model of a normal right atrium (RA) from computed tomography data. We developed a test protocol consisting of two activities: creation of a RA shell and timed navigation to specific locations within the RA shell. Seventeen participants were randomized to either practice versus no practice on the simulator, and repeated simulator and self‐assessment tests were performed after 1 week. We measured volume of the RA map and time taken and distance from the target sites for each target location. Results Both groups showed improvement in generation of geometry, volume, time to target, and self‐assessed comfort level after initial exposure to the simulator. Compared with no‐practice, the practice group demonstrated an improved sense of confidence in mapping. Conclusions Focused training in EP mapping using a novel simulator created with 3D printed heart models and a standard mapping system is feasible for use in the training environment. Exposure to the simulator is associated with improved mapping skills and trainee comfort level.
