Heart transplant: Hannah's story

Fifteen year old Hannah could pretend her heart wasn’t a problem during marching band practice by “fake playing” as she paraded around the field. But eventually, the cardiomyopathy that plagued her family forced her off the field and into a hospital bed. There, she could only wait for a donor heart to save her life. Hannah became the first heart-transplant patient at Children's Mercy.
