Zebrafish, whose genetic structure is quite similar to humans', can regenerate their hearts after injury unlike humans, whose hearts scar after damage. Keating's hope is to identify the self-repair genes and eventually find ways to stimulate human hearts to grow anew, too. More... Statistics & Outcomes Despite treating some of the most complex pediatric heart conditions in the world, the Cardiovascular Program at Children's Hospital Boston has some of the best success rates.

Research Spotlight: The Causes and Cures of Arrhythmias David Clapham, MD, PhD, director of Basic Cardiovascular Research at Children's, and his colleagues are researching what triggers ion channels to open or close, how they know to filter out certain ions, and how they throw off heartbeats -- creating arrhythmias. He also has worked to design anti-arrhythmic drugs that work only where needed, so they don't affect other parts of the heart.
