The heart is a remarkable thing. At 21 days after conception, it's the first organ in the body to develop and function, and 99% of the time, everything in its development goes perfectly.  However, for 1% of babies, something in this process goes wrong, and the effects can be devastating. Join host Derren Raser as he explores what late author Brian Doyle calls "the wet engine." He also speaks with physicians in order to examine what it means for a child to have congenital heart disease (CHD), and recalls, with his wife, their own personal family story of receiving a CHD diagnosis for their daughter.  Woven with narrative, human stories, and a wealth of fascinating information, this episode of One Rare Heart will immerse and inspire.
