The first domestic 3D printing "repairing heart hole" surgery was a complete success

In recent years, 3D printing technology has become a well-known innovation in the medical field. From 3D printed prosthetics to bio-printed tissues, this cutting-edge technology has been successfully applied in hospitals around the world. What was once considered impossible—like 3D printed limbs, ears, and even organs—is now becoming a reality, revolutionizing the way we approach healthcare. At just three months old, a baby known as "Morning" (a pseudonym) was frequently hospitalized due to repeated bouts of pneumonia. After a thorough medical examination, doctors discovered that the child had a congenital heart defect—specifically, multiple holes in the heart. Immediate surgery was necessary, but the situation turned complicated after the first operation. The doctor found more holes than initially expected, and the child struggled to breathe on his own afterward. To better understand the complex condition, the medical team decided to use 3D printing technology to create a detailed model of the baby's heart. This allowed them to simulate the surgery multiple times, ensuring they were fully prepared for the second operation. With the help of the 3D-printed heart, the surgeons successfully repaired the defects, giving the child a new chance at life. The child’s parents were deeply worried from the start. From birth, Morning had been weak and required frequent hospital visits. By the time he was three months old, he had already been admitted three times due to severe pneumonia. Concerned about his health, the family sought treatment at Nanjing Children’s Hospital, where doctors confirmed the presence of serious congenital heart disease. Dr. Sun Jian, a senior cardiac surgeon, explained that the child had multiple ventricular septal defects and a large atrial septal defect, which caused significant blood flow issues and led to high pulmonary pressure. He also noted that the child’s mother had a history of heart disease, suggesting a possible genetic link. Despite the risks, Dr. Sun emphasized the urgency of the surgery. However, the child’s small size and fragile condition made the procedure extremely challenging. The parents were torn between the fear of surgery and the risk of not acting at all. Ultimately, after a detailed discussion with the medical team, they decided to proceed with the operation. Thanks to the advanced 3D modeling and careful planning, the second surgery was successful. The child’s heart was repaired, and he began to recover. Today, the family is grateful for the breakthrough in medical technology that saved their son’s life.
