The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) is a voluntary registry that contains preoperative, operative and outcomes data for all patients undergoing congenital and pediatric cardiovascular operations at participating centers. It is the world's largest database for these operations.
STS-CHSD contains data on more than 300,000 operations done since 1998 at 119 hospitals in North America. More than 95 percent of all U.S. centers that perform pediatric heart surgery are included in the database. As a result, the data represents more than 95 percent of all pediatric and congenital cardiac operations in the United States.
