Research at the Blalock-Taussig-Thomas Pediatric and Congenital Heart Center

The Blalock-Taussig-Thomas Pediatric and Congenital Heart Center is host to a team of researchers expanding what we know about pediatric and congenital heart conditions and how to apply those findings to patient care.

Learn More and Get Involved

We understand that it takes the involvement of many to further the development of treatments for children across the world. This involves working with students, as well as patients and families, to achieve these discoveries.
