Engineers can now print three-dimensional replicas of a human heart custom-designed to look and act like an individual patient’s heart.
A researcher holds a customized, 3D-printed heart made to mimic the shape and behavior of a patient's heart.
“In patients with heart failure, they have very different anatomy,” she said. Each heart is unique, and there’s even more variation for patients with heart failure. One day, doctors could use this type of robotic heart for patients with aortic stenosis, a condition in which the aortic valve narrows and, thus, forces the heart to work harder to pump blood throughout the body, according to Rosalia and Roche. This condition affects 1.5 million people in the United States. Usually, aortic stenosis is treated through surgically implanting a synthetic valve.
But Passeri — who was not involved in the 3D heart replica research — called the new technology “fascinating.”
