3D Printed Heart and Materialise’s Efforts in Bioprinting
Most recently Brooklyn surgeon, Dr. Emile Bacha, used a 3D printed model to repair the heart of a newborn baby whose heart was riddled with holes, very possibly saving the child’s life. The baby had a heart that was literally just the size of a walnut. Todd Pietila, Cardiovascular Business Development Manager at Materialise, had been working on the project since the baby was born. He made a 3D model of the baby’s heart with Mimics Innovation Software, and then 3D printed a a model for doctors to use, being able to view even the most minute details of the tiny heart.

“After the success of this surgery, it’s hard to imagine entering an operating room for another complex case without the aid of a 3D printed model. It’s definitely going to be standard of care in the future and we’re happy to be leading the way,” said Dr. Emile Bacha, a congenital heart surgeon and Director of Congenital and Pediatric Cardiac Surgery at NewYork-Presbyterian/ Morgan Stanley Children’s Hospital.
We also covered the much publicized story of Bradley White, who was born with a tumor in his heart and had endured open-heart surgeries as a toddler. At the age of 16, the tumor was causing him to have an irregular heartbeat, and specialists on staff at Cincinnati Children’s Hospital called on Materialise for help.
Using their Mimics Innovation Software in this instance also, Todd Pietila created a model of Bradley’s heart and tumor, delivering a 3D printed copy to cardiologist Dr. Timothy Knilans, and cardiac surgeon Dr. David Morales, who decided, based on looking at the model, not to operate and to perform an alternative procedure.

The 3D-printed models are custom-designed from medical image data specific to patients, such as scans and X-rays. The models provide cardiologists and surgeons with supplemental information to determine the best treatment for each unique patient.
It’s already clear that Materialise is on the forefront regarding extremely important and complex innovations with 3D printing technology, but with the Class 1 rating, they will be afforded the opportunity to add HeartPrint models to their offering for pre-operative planning. The FDA classifies medical devices based on risk, with three different levels. Class I devices are considered low risk by the FDA and are not subject to as much regulatory control.
“Where I think clinically 3D printing will take us, is to the next generation of imaging. As we’ve seen in the history of medicine, the better and better our imaging, the more precise we are to pre-operatively be able to say what operation we’re going to do,” said David Morales, MD, Chief of Cardiovascular Surgery for the Heart Institute at Cincinnati Children’s Hospital Medical Center.
“We’re proud that the Mimics Innovation Suite is one of the few engineering packages with the appropriate validation to be considered a medical device. This makes it easier for Materialise and our customers to bring patient-specific, 3D-printed treatments to the market. It’s important for us to stay ahead of the regulatory requirements,” Koen Engelborghs, Director of Biomedical Engineering at Materialise, states. “We saw the advantages for patients when HeartPrint models were used in a clinical environment and are looking forward to continuing our collaborations with hospitals to address their 3D printing needs.”
