For weeks, Gretchen and Jason Biringer thought their 7-year-old son, Evan, had the flu because the typically energetic boy was lethargic. When Evan’s nailbeds turned purple and he had trouble breathing, they took him to the local emergency room, and he was then transported via helicopter to Johns Hopkins Children’s Center.

The family learned that Evan had biventricular heart failure and would need a heart transplant. Jason and Evan Biringer discuss their transplant donation experience at Johns Hopkins Children’s Center.
