3D printing technology helps to recreate 100% of the human heart model

A 3D printed heart model saved the life of a 14-month-old boy during heart surgery. This is the result of the creation of engineers at the JB Speed ​​School of Engineering at the University of Louisville.

Scientists have created a 3D printed model of a child's heart that allows doctors to better plan before surgery is performed.

Philip Dydysnki, chief of radiology at Kosair Children's Hospital, turned to the University of Louisville for help as he and his team sought to treat Roland Lian Cung Bawi, a boy born with four congenital heart defects.

At the research center, Dr. Philip was impressed with the capabilities of 3D printing technology there.

Using CT scans of Roland’s heart, the researchers created a 3D printed model of the heart that is 1.5 times larger than the real thing. The heart is made of three parts made of flexible fibers, took about 20 hours to make, and cost a total of $600.

Cardiac surgeon Erie Austin III, MD, who led the surgical team, used a model of the heart to help devise solutions and plan the surgical procedure. Ultimately, the team was able to correct all the defects in a single operation on February 10.

“I think the heart model is the solution to planning this very complex heart surgery,” said Dr. Austin.

After the surgery, Roland was discharged from the hospital on February 14. Currently, his health is in a normal recovery state after returning for a follow-up check-up on February 21.

For researchers at the University of Louisville, the success of the 3D-printed heart surgery has expanded the scope of applications for this advanced technology. Previously, researchers had focused on developing 3D printing technology for manufacturing and heavy industry.

“Knowing that you can make someone's life better is a truly wonderful experience,” said researcher Gornet.
