Heart Murmur

London Eisenbeis had waited two years to ride the giant slide, but her family never thought the thrilling experience would end up killing their 10-year-old.

Eloise Hoffman was born with truncus arteriosus, a rare heart condition.

Lee’or and Wendy Rutenberg, of Seattle, Washington, didn’t know what the future would hold when their daughter Sadie was born with a life-threatening heart defect. Now, three years later, the little girl has defied the odds thanks to a newly-approved half-inch heart valve.

The talk show host tearfully revealed on "Jimmy Kimmel Live" that his newborn son Billy had open heart surgery last week to correct a birth defect.

Congenital heart defects, or abnormalities in the structure of the heart and blood vessels, are the most common type of birth defect, affecting approximately one out of every 100 babies born in the United States.
