This week Chinese doctors 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. 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. The surgery was successfully completed on March 11th and Doctors estimate that with the 3D printed heart replica it took them half as long as it typically would have.
