Multicenter Clinical Research in Congenital Heart Disease: Leveraging Research Networks to Investigate Important Unanswered Questions.

Congenital heart disease (CHD) is the most common birth defect in the United States. Neonates with CHD are often cared for by neonatologists in addition to cardiologists. However, there is a paucity of rigorous evidence and limited clinical trials regarding the management of neonates with CHD. In this review, we will describe some of the challenges of research in this field. The Pediatric Heart Network serves as an example of how a research network can effectively overcome barriers to conduct and execute well-designed multicenter studies.
