Seventy-five years ago, Boston Children’s didn’t just start a cardiology department. It brought together dedicated and highly inventive clinicians, researchers, and support staff who, generation by generation, have improved the lives of children with heart disease and made Boston Children’s the leader in pediatric cardiology. The Department of Cardiology has much to celebrate on its 75th anniversary; watch how it all happened and how we hope to build upon our successes over the next 75 years.
