First pediatric heart transplant completed at Children's Mercy

The last thing Hannah Mountz remembers before passing out was, "Should I tell my grandma?"

That was about five weeks ago, as the 15-year-old Kansas City, North, girl sat in her room putting on makeup while her grandparents waited downstairs. Hannah felt what had become the frequent and unwelcome sensation of her heart skipping a beat. This time, a defibrillator that doctors had implanted in her chest shocked her heart five times, delivering five jolts of increasing voltage, before her heart beat normally.

Hannah was put into intensive care at Children's Mercy Hospital. And on Feb. 13, she became the first patient to receive a heart transplant at the hospital.
