Washington State University researchers have made a groundbreaking advancement in medical training with the creation of a 3D-printed heart model that contracts and beats like a real heart. This innovative technology offers a unique opportunity for surgeons and medical students to practice complex heart surgeries on a lifelike replica, potentially revolutionizing the way medical education is conducted. The model, developed by Kaiyan Qiu and Alejandro Guillen Obando, is the first fully synthetic model that mimics the complete left side of the heart without relying on animal models. It incorporates both anatomic features and dynamic functions, making it an invaluable tool for medical professionals. The researchers used a scan of a real heart to 3D print the replica, which includes the atrium, ventricle, and mitral valve, and has a soft texture similar to a real heart. It also has multiple tiny pneumatic actuators that pump the model and string-like material that manages the mitral valve movement. The model's unique design allows for the addition of more curvature and the simulation of a real heart's chambers. The researchers demonstrated the model's capabilities by repairing a defective mitral valve and monitoring the increased blood pressure in the left ventricle, indicating the valve was fully closing. The model's potential applications are vast, from training for major surgeries to conducting patient-specific, pre-surgical rehearsals for different valve diseases. The researchers have filed a provisional patent and are now working to develop a complete heart model with all four chambers and four valves, marking a significant step forward in medical training technology.
