After six months and a historic transplant, Sarah Murnaghan is back home

Sarah Murnaghan, the 11-year-old girl whose plight led to a national change in lung-transplant rules,  was released on Tuesday and is now back home in Newtown Square.

Sarah, who has cystic fibrosis, entered Children's Hospital of Philadelphia in February in dire need of a double lung transplant. Although she remains very weak, she has made remarkable progress since June, when she received two double-lung transplants of adult organs within days.

Sarah had waited 18 months for children's lungs before her family waged a media campaign and filed a federal lawsuit to have her placed on the adult-transplant waiting list.

Her first pair of adult lungs failed immediately after the surgery, so her parents agreed to a desperate last resort, allowing doctors to transplant adult lungs infected with pneumonia that would normally be rejected.

Her parents said they would hold a news conference at their home on Tuesday afternoon to talk about Sarah's ongoing recovery.
