3D printed heart simulated organs
Mia Gonzalez spent the first 3½ years of her life missing out. She had to skip day care and dance classes because she constantly had colds and pneumonia. When Mia could go out and play, she was easily winded and took multiple asthma medications to try to help her breathing.
After about 10 hospital stays, doctors realized that Mia had a malformation in her aorta, the vessel that pumps blood from the heart. The 4-year-old would need an operation to close off the part of her aorta that was putting pressure on her windpipe and making it hard to breathe, swallow and get rid of phlegm when she got a cold.
But Mia’s malformation was complicated. The surgeons at Nicklaus Children’s Hospital in Miami, where Mia was treated, might have been apprehensive about the procedure were it not for a new technology: the 3-D printer.
3-D-printer changed girl’s life
Earlier this year, the hospital got a 3-D printer that makes exact replicas of organs that doctors can use to plan surgery, and even do practice operations. The printer uses images from patients’ MRI or CT scan images as a template and lays down layers of rubber or plastic.
Dr. Redmond Burke showed it to colleagues for their input and even carried it around in his gym bag for quick reference.Burke finally had the “Aha!” insight. Instead of making an incision on the left side for this type of heart defect, called double aortic arch, he should cut into Mia’s chest from the right.
He attributes the model with saving the team and patient about two hours in the operating room because he was able to have a clearer plan to do the surgery.
Burke and his colleagues have created models for about 25 young patients with congenital heart defects. In the past, they might not even have operated on some of these patients because the surgeries seemed too tricky
Doctors have used the simulated organs to prepare for all kinds of tricky operations, such as surgery to remove a brain tumor or to correct a severe cleft palate. Doctors can operate on them with regular surgical tools again and again and again until you think of the optimal way to do surgery.
