Researchers at Washington State University have created a 3D-printed, beating heart model that they believe could significantly improve how doctors prepare for complex heart surgeries. The model is designed to mimic the look, feel, and function of a real human heart, allowing surgeons to practice procedures beforehand.

Why it matters

Current heart surgery planning often relies on 2D imaging or cadaver models, which have limitations. This new 3D-printed heart could give surgeons a much more realistic and customizable tool to rehearse procedures, potentially leading to better outcomes for patients.

The details

The WSU team used advanced 3D printing techniques and materials to create the beating heart model. It includes a realistic cardiac muscle that can contract and expand, as well as valves, chambers, and blood vessels. Doctors can even connect the model to a pump to simulate blood flow.

  • The 3D-printed heart model was recently developed by researchers at Washington State University.
  • The new technology is expected to be available for use in hospitals within the next 1-2 years.
