Advanced 3D printing techniques create replica organs to better educate doctors and patients and improve the safety and efficiency of procedures.
TAMPA, Fla., May 19, 2022 /PRNewswire/ — How do you mend a broken heart? With plastic. That’s a goal at Tampa General Hospital, where a sophisticated 3D printing program makes replicas of human organs from layers of man-made materials. In collaboration with USF Health Morsani College of Medicine’s Department of Radiology, Tampa General has used 3D printing to plan aortic valve replacements, trauma surgery, cancer surgery and other reconstructions, as well as the creation of replicas of major organs. Replicas are used by surgeons to improve surgery planning with the goal of improving the surgical experience and patient outcomes.
“We are able to translate medical imaging data into 3D models and these can be used in clinical decision making, medical simulation and training, and patient education,” said Summer Decker. , PhD, Associate Professor and Director of 3D Clinical Applications for the Department of Radiology at USF Health Morsani College of Medicine.
This potentially revolutionary technique uses 3D-printed facsimiles to better understand treatment and even reduce risk in invasive and complex surgeries. It allows the evaluation of an organ outside the body, which saves time in the operating room and reduces costs. “With this 3D technology, we can reduce an 11-hour surgery to a three-hour surgery,” Decker added. “So it makes the procedures safer and more efficient.”
USF Health Morsani College of Medicine and Tampa General are the first in the Tampa Bay area and among the first in the country to use this innovative technology. Although this collaborative 3D printing program began years ago as research, it has evolved into a valuable medical asset today. Early in the COVID-19 pandemic, for example, Dr. Charles Lockwood, Senior Vice President of USF Health and Dean of Morsani College of Medicine, asked the USF Health 3D Lab team to develop a solution. to the international shortage of supplies for the nose. swabs needed for COVID-19 testing. In collaboration with USF’s Division of Infectious Diseases and the Global Emerging Diseases Institute at Tampa General, the team designed and developed an alternative 3D-printed nasopharyngeal swab for COVID testing. Validation of the swab’s accuracy took place at several healthcare facilities across the United States, including Tampa General Hospital. To date, USF’s patent-pending design has produced more than 75 million swabs in more than 50 countries.
A swab is one thing; one heart is another. The artificial version gives doctors and patients a better understanding of the problem at hand. So if a patient has a diseased heart, doctors can scan it, print it, and collaborate on a strategy based on the printed model. Just as important, they can put it in the hands of the patient. “It gives our patients and doctors a better understanding of the problem and how best to treat it,” said Dr. Krishna Nallamshetty, chair of the radiology department and associate professor of radiology and cardiology at USF Health. Morsani College of Medicine and Chief of Staff at Tampa General Hospital.
A 3D printed anatomical model or surgical cutting guide is made using different types of medical imaging such as computed tomography (CT) or magnetic resonance imaging (MRI). Then a 3D printer makes a copy of the object through a series of compiled layers. This “additive manufacturing” process deposits extremely thin layers of material in liquid form and fuses them together to create a replica of the digital file. The technique can create complex shapes and sizes with minimal materials, so it’s quick and relatively inexpensive.
“It’s true from bench to bedside in a short period of time, often the same day,” Decker said. “We can scan the patient, create a computer model of the organ, or design a surgical cutting guide, use that to collaborate with all the teams so they know exactly what they need, print it out, and then rub it in for surgery. It’s an innovation that’s helping to change the outcome for the patient.”
“Having an exact replica of a patient’s real heart — including any defects — is an invaluable tool, especially when it can be created in less than a day,” said Jonathan Ford, PhD, assistant professor and biomedical engineer. , Department of Radiology, USF Health Morsani College of Medicine and Technical Director of 3D Printing, Tampa General Hospital. “A heart will take about 15 hours to reproduce on the printer, so by the time we return in the morning we can hand the printed heart to the surgeon for reference.”
The 3D clinical applications team currently houses seven medical-grade 3D printers. The team has been located at the USF Health South Tampa Center for Advanced Healthcare on the Tampa General campus for eight years. The team plans to move its 3D lab and printers inside the hospital’s main radiology department, providing better access for surgeons and other clinicians in Tampa General.
Decker and USF Health’s 3D Clinical Applications Team were also recognized for their work on 3D-printed nasal swabs with the inaugural Jack A. Kolosky Award for Innovation in Healthcare from Tampa Innovation Partners in 2021. The Kolosky Award is named for the retired president of Moffitt Cancer Center and recognizes innovation in health care.
Additionally, for his pioneering work with the 3D-printed swab, Decker was one of three USF Health faculty members in June 2021 to share the national spotlight with healthcare professionals across the country — including including the Chief Medical Advisor to the President of the United States. , Dr. Anthony Fauci – for being named the 2021 Humanistic Care Champions by the Arnold P. Gold Foundation.
“It’s really about the power of the collaboration between USF and Tampa General, because the work being done here is truly transformational,” said John Couris, president and CEO of Tampa General Hospital. “It makes a huge difference for our doctors and for our patients.”
