This week Chinese doctors have had another first after they successfully performed a dangerous open heart surgery on a nine-month-old baby suffering from a severe heart defect using a 3D printed heart model to plan the surgery. Despite being born a healthy 12 pounds, the baby was quickly found to be having a shortness of breath. Doctors discovered that the baby had a severe Congenital Heart Defect called a Total Pulmonary Venous Anomalous Drainage. The child was born with all four of his pulmonary veins malpositioned and he also suffered from an atrial septal defect which caused blood to flow between the upper chambers of the heart.
“He was taken to the hospital and was critically ill with heart failure and severe pneumonia, because the boy is so young and small, it was difficult to develop the best surgery plan using just an ultrasound examination. If treatment had been delayed, the baby’s chance of dying before his first birthday would have been as high as 80 per cent,” explained Zhang Xueqin, the director of the paediatric cardiac surgery center at the People’s Hospital of Jilin and the baby’s surgeon.
This was the first time that a full-sized 3D printed model of a patient’s heart was used to pre-plan a complicated surgery of this nature in China. The defect that the child was suffering from is quite rare and extremely difficult to repair. However with the 3D printed heart replica the operation was completed on March 11th and the baby has already been transferred to a general ward and is expected to survive with little to no lasting ill effects.
“With the model, we were able to know precisely where and how we should cut, and how big the incision should be. And with such a thorough plan, we spent only half the time we had expected to complete the surgery,” Doctor Zhang Xueqin said.
