Heart-swap schoolgirl Sally Slater has teamed up with football presenter Gabby Logan in an effort to give others the chance of life.
In March 2000, Sally was rushed into Newcastle's Freeman Hospital after a virus attacked her heart.
She was suffering from a condition known as dilated cardiomyopathy, the most common cause of heart failure leading to the need for a transplant in children.
For five days, she was kept alive by an artificial pump while her parents made a public appeal for an organ donor that could save their six-year-old daughter's life.
Doctors had almost given up hope when, at the 11th hour, a donor was found.
Two years on, Sally is leading a normal and active life. She is now helping the National Cardiomyopathy Association launch a campaign to boost the number of potential organ donors by urging people to sign the donors' register.
Her parents, Bridget and Jon, who live in the North Yorkshire village of Malham, said: "We would just like to urge people to please think about donating their organs."
Also supporting the campaign is former Durham University student Gabby Logan, who lost her brother to the disease.
Chief executive of the Cardiomyopathy Association Gordon Rae said: "We're asking everyone to join the NHS organ donor register and carry an organ donor card."
