At simply two years outdated, LM (a affected person whose full title is withheld for privateness) was dwelling with a uncommon and life-threatening coronary heart defect that made each heartbeat a battle. Normal surgical planning instruments couldn’t totally seize the complexity of the kid’s situation, however a brand new form of collaboration supplied a special path. Utilizing superior 3D modeling and blood-flow simulations, the surgical crew was in a position to plan and carry out a extremely customized operation that will have modified the course of the kid’s life.
The hassle was led by pediatric cardiac surgeon Ignacio Berra of Garrahan Hospital in Buenos Aires, Argentina, who teamed up with researchers on the Balseiro Institute—a number one nuclear science and engineering heart based mostly in Bariloche, a metropolis nestled within the Andes within the far south of the nation. Collectively, they’re making use of scientific modeling to one of the crucial tough areas in pediatric surgical procedure: navigating the unpredictable anatomy of youngsters born with advanced coronary heart defects.
By changing medical photos into detailed 3D fashions and simulating blood circulation by means of the affected person’s coronary heart, the crew was in a position to plan the process all the way down to the millimeter earlier than getting into the working room (OR). This strategy provides surgeons a a lot clearer sense of what to anticipate and the way greatest to proceed. LM was the primary affected person to learn from this methodology, however the crew hopes many extra will observe.
Berra brings a wealth of worldwide expertise, together with a two-year fellowship in cardiac surgical procedure at Boston Youngsters’s Hospital, in addition to extra coaching at establishments reminiscent of Leeds Youngsters’s Hospital within the U.Okay., below the steering of Dr. Carin van Doorn, a globally acknowledged skilled in congenital cardiac surgical procedure. For this venture, he joined forces with a multidisciplinary crew from the Balseiro Institute, led by engineer and principal investigator Enzo Dari.

Reconstructing a Beating Puzzle
The method begins with customary imaging—CT or MRI scans—of the younger affected person’s coronary heart. Within the case shared with 3DPrint.com, the kid had a uncommon congenital coronary heart defect that severely affected the traditional blood circulation. Relatively than relying solely on 2D scans and surgical expertise to know the malformation, Berra turned once more to superior expertise.
He despatched anonymized scans to researchers at Balseiro, the place the crew created a 3D digital mannequin of the center utilizing specialised software program. Each chamber, vessel, and abnormality was rendered in full shade and element.
Subsequent, they ran simulations to mannequin how blood would circulation by means of the malformed coronary heart. With strain maps and directional circulation information, the crew might visualize how blood would behave below totally different surgical eventualities, lengthy earlier than a single incision was made.
From Digital Coronary heart to Working Desk
The collaboration didn’t cease on the display screen. Earlier than the surgical procedure, the crew took issues a step additional. They 3D printed a full-scale mannequin of the affected person’s coronary heart, and related it to a pulsatile pump that mimicked the rhythm of actual blood circulation. This allowed them to recreate the kid’s situation in a lab setting, pressurizing the aorta and testing how blood would circulation by means of the repaired coronary heart.
The 3D printed mannequin additionally served as a mould for shaping a customized Gore-Tex patch, a tender, medical-grade materials typically utilized in coronary heart surgical procedures. The patch was designed to create a tunnel between the left ventricle and the aorta. In brief, the crew didn’t simply simulate the operation—they practiced and refined it forward of time.
Armed with detailed fashions and exact measurements, Berra and his surgical crew entered the OR to carry out the process. Sutures have been positioned, patches added, and valves rigorously reconstructed, all based mostly on the pre-surgical planning completed with the Balseiro fashions. With out that stage of planning, the process would have carried even increased dangers.

An Unlikely however Highly effective Staff
A partnership between a number one youngsters’s hospital and a nuclear science institute would possibly sound uncommon, however on this case, it made excellent sense.
Balseiro, which operates below Argentina’s Nationwide Atomic Power Fee (CNEA), trains lots of the nation’s high minds in physics, engineering, and utilized science. In recent times, researchers there have developed experience in fluid dynamics, biomechanics, and simulation—all instruments with clear potential in healthcare.
In the meantime, Garrahan handles among the most demanding pediatric surgical procedures in Argentina and all through Latin America. As a part of the nation’s public healthcare community, the hospital provides free care to sufferers from throughout the nation, in addition to from neighboring international locations reminiscent of Bolivia, Paraguay, and Peru.
By crossing disciplines, Berra and the Balseiro crew are altering how high-risk surgical procedures are ready and carried out. As an alternative of getting into the OR with restricted info, surgeons can now depend on detailed simulations, 3D fashions, and customised planning instruments.

Why This Issues
Whereas 3D planning and simulations are starting to emerge at main surgical facilities in Europe and the U.S., this stage of interdisciplinary collaboration stays uncommon in Latin America. That’s a part of what makes this story so notable.
Berra and the researchers at Balseiro aren’t simply utilizing high-tech instruments; they’re redefining what’s potential when two very totally different establishments work along with a shared objective: to provide youngsters with critical coronary heart situations a greater likelihood at life.
“This isn’t nearly expertise,” Berra informed 3DPrint.com. “It’s about giving medical doctors extra confidence earlier than surgical procedure, and giving sufferers a greater shot at survival. The venture additionally reveals how experience from fields like physics and engineering, historically far faraway from the OR, can have a direct and lasting influence on medical care.”
Because the collaboration continues, the crew hopes to increase its strategies, incorporating extra 3D printing and new simulation instruments to plan advanced procedures upfront.
On the heart of all of it is a perception that Argentine establishments can obtain extra once they work collectively, and that when used successfully, expertise is greater than only a device. It’s a lifeline.
Who Made It Occur: The venture introduced collectively a various crew of pros from each the medical and engineering fields. From the Balseiro Institute, contributors included researchers Paola Córdoba Estrada and Daniela Lucía Arnica, multimedia designer Pablo Takeuchi, electronics engineer Sebastián Berra, and industrial designer Alfredo Irusta, who brings expertise from Argentina’s Navy design corps. From Hospital Garrahan, the surgical crew included pediatric cardiovascular surgeons Laura Zenobi, Rocío Boudou, Javier Cornelis, and Pablo García Delucis, alongside pediatric cardiologists Julia Blando and Fernando Diez Mori, in addition to Guido Corna Frasson, a specialist in automation and robotics.
