There are many milestones in pregnancy, and they are generally all very exciting—whether it is your first baby or your fourth. Verifying that you are really pregnant is the first step, but it seems that once you do so with a home pregnancy test, then it’s on to many months of constantly making sure and waiting for repeated reassurance that everything is all right—all the way through delivery.
The ultrasound is a breathtaking experience for parents-to-be, and especially in the first weeks. While you can’t make out much at that point, there is one small but extremely important body part you can both see and hear: the heart. I must say, even today, when my young daughter is cuddled up next to me, settled in and sleepy, I can often feel her heart beating, and I’m taken right back to that moment when the ultrasound technician first located her heart on the screen and showed it to me. It’s the most literal sign of life, and beyond that all that, a parent wants to know that the budding life and heart are also okay—and if not, a thorough explanation is certainly required.
In those first months, evaluation is very important. While you may expect that everyone checking out your unborn child’s heart knows exactly what they are doing, it’s not an easy science. And the experts at MWU in Poland—a school dedicated to the education of reading and evaluating ultrasounds—have come forth to point out that many doctors, technicians, and even specialists find a comprehensive understanding of the fetal heart in 3D to be daunting at times. They’ve spent many years trying to find solutions for that, stemming in deeper education and better tools.
Continued learning lies at this heart of this matter, but for a 3D science, the models need to reflect that in the best way possible, leading to a superior ultrasound reading. And while we’ve followed so many stories regarding 3D printed models helping in complex surgeries such as that of jaw reconstruction and even saving a spleen, this context provides the perfect example of how the models are so valuable just in training, for everyone.
Most women (and babies) are lucky, and every ultrasound concludes in hugs, smiles, and a stack of 3D pictures that can be shared with families and friends in joy, but unfortunately sometimes there can be an issue or congenital defect. Early detection is crucial, and evaluations should be precise. The MWU group realized over time that heart models made through traditional methods and sold commercially did not clearly display the ‘layered arrangement of elements,’ in even the adult heart.
In exploring further, MWU realized in their studies of fetal heart models that they needed more realistic tissue tension to serve as a viable tool in understanding how to test a live heart. And not only that, one of the biggest roles in the job of an ultrasound technician is interacting with parents. With one of MWU’s heart models, the medical professional has a substantial visual aid to use for describing the baby’s heart, putting the 3D medium right into the parents’ hands. While this is very important in any case, it’s especially helpful during a sensitive situation where there might be a problem, and parents should have every avenue to understanding what is going on. According to MWU, parents are much more receptive to the models, based on ultrasound images, as opposed to 2D drawings or diagrams.
“These models are an important tool in the education of obstetricians-gynecologists and physicians interested in prenatal ultrasonography,” states MWU.
In creating better models for the benefit of both medical professionals and patients, three teams collaborated on the 3D printed heart models. The GRID company, known for their industrial design expertise, was responsible for initiating the entire project, bringing in Rapid Crafting, also headquartered in Warsaw. Specializing in 3D modeling and printing, Rapid Crafting was able to create a truly impressive and extensive library of models for sale, depicting a wide range of conditions.
Each model is 10 x 14 x 10 cm, and includes instructions as well as illustrations detailing each layer of the model. There are over 40 different displays to choose from, with some showing how a proper heart should look, along with many examples of different defects emerging at birth.
“I was skeptical at first,” said Dr. Agnieszka Nocun, MWU co-founder and lecturer. “But at my visit at GRID when I saw their professional approach and how the model was built from the very basics, A to Z, I agreed with Marcin [Wiechec, co-founder] that it was a really great idea, and our models constitute a great form of educational tool for physicians.”
While this is a perfect start for extending education further in the field of ultrasound technology, 3D printed medical models continue to help advance the medical field—with some hospitals and medical facilities even creating entire lending facilities, like the 3D Printed Heart Library at Jump Trading Center in Illinois. All of these models mean so much more than just a piece of plastic representing a human organ. They can be customized to look exactly like a patient’s heart—or brain, or kidney, or liver—and can be shown with a condition or tumor just as it appears in the body, allowing for diagnostics, treatment, and navigation in surgery.
“Our models also had proven themselves during patient consultation,” states the MWU team. “Among others during our workshop in March 2016, we detected a heart defect during practical classes in one of the patients.”
With the 3D printed fetal hearts, everyone involved is able to be better educated, as well as informed on how to move forward when there is a potential issue or defect involved. As the technology continues to evolve, so will the models, in a variety of different intricate designs and materials. If a picture is worth a thousand words, then certainly one of these customized cardiac models is worth hours of training via the chalkboard.
