The Congenital Heart Disease Research Registry (CHDRR) is a program dedicated to understanding the etiology and improving the treatment of Congenital Heart Disease (CHD). This Registry will act as a central coordinating center for recruiting subjects with CHD and will provide infrastructure and guidelines for researchers studying the causes and treatment of CHD. Investigators working directly with the Registry will have access to biological, demographic and phenotype data from a significant pool of participants with CHD.
