Researchers have 3D-printed a heart model that mimics the complex movements of the left side of the heart. This model includes atrium, ventricle, and mitral valve, offering surgeons a realistic platform to practice patient-specific presurgical simulations. 

To enhance structural realism, sutures connect the ventricle to the mitral valve, imitating “heartstrings”, enabling the model to act like real tissue during practice procedures.
