Arlo Fischer is a baby who was born with a malformed heart.
History[]
Arlo was born with truncus arteriosis and a ventricular septal defect. He was immediately placed on the list for a heart transplant. A week after his birth, he had to be put on ECMO. A week after that, a heart became available, but the procurement team determined it was too damaged to be viable for transplant. Maggie had the idea to take that heart and cut out the parts that were damaged in Arlo's heart and use them to repair Arlo's heart. Unlike a transplant, the transplanted valves would grow with Arlo, meaning he wouldn't require a transplant later. His parents agreed to the surgery, but then decided it was too risky. After Amelia Shepherd shared her experience with her son, they decided to go ahead with it. The surgery was successful and Arlo's heart was beating on its own afterward.
