The first report of The Society of Thoracic Surgeons (STS) National Congenital Heart Surgery Database in 1998 reported the clinical features of 18 congenital heart categories. The report provided a significant amount of important information and also highlighted the strengths and weaknesses of the existing database. Following this report the STS Congenital Heart Surgery Committee in cooperation with the European Association of Cardio-Thoracic Surgery and the European Congenital Heart Surgeons Foundation initiated the International Congenital Heart Surgery Nomenclature and Database Project. The goal was to begin the standardization of nomenclature reporting strategies and establish the foundations for an international congenital heart surgery database. The first report of the International Congenital Heart Surgery Nomenclature Project was published in The Annals of Thoracic Surgery in April 2000. The current report outlines modifications to the minimum dataset as well as the diagnoses and procedure short lists. Plans for the next STS National Congenital Heart Surgery Database harvest are also presented.
