Currently, no tailored surgical models exist for minimally invasive cardiac procedures leaving surgeons to learn primarily on patients. These procedures, such as catheter ablation and the WATCHMAN left atrial appendage closure, are performed by placing a catheter through the femoral vein to access the heart. To address this gap, we have developed an anatomically accurate and patient-specific training model. Using CT and MRI scans from the Mayo Clinic, we created a 3D-printed model with Materialise Mimics, Materialise 3-Matic, and SolidWorks software. The system includes a torso, leg, interchangeable hearts, and a femoral vein pathway. Cameras are in place to mimic the fluoroscopy that would be used in an actual procedure. A visual and audio feedback system identifies key ablation points in the heart. Together, these features allow for the creation of an educational model. Surgical outcomes utilizing the educational model will be compared with previous outcomes for surgeons of various education and experience levels. This project will reveal if customizable practice models are significantly beneficial to surgical practice by observing patient outcomes.
