3D-printed organ model can improve surgical outcomes for heart patients

Researchers from the University of Minnesota, with support from Medtronic, have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart’s aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.

 .

These patient-specific organ models, which include 3D-printed soft sensor arrays integrated into the structure, are fabricated using specialized inks and a customized 3D printing process. Such models can be used in preparation for minimally invasive procedures to improve outcomes in thousands of patients worldwide.

 .

The research is published in Science Advances , a peer-reviewed scientific journal published by the American Association for the Advancement of Science (AAAS). The researchers 3D printed what is called the aortic root, the section of the aorta closest to and attached to the heart. The aortic root consists of the aortic valve and the openings for the coronary arteries. The aortic valve […]
