Congenital Heart Surgery Database and Nomenclature Project: Aortic valve disease

The extant nomenclature for aortic valve disease is reviewed for the purpose of establishing a unified reporting system. The subject was debated and reviewed by members of the STS-Congenital Heart Surgery Database Committee and representatives from the European Association for Cardiothoracic Surgery. All efforts were made to include all relevant nomenclature categories using synonyms where appropriate. Aortic valve disease has been subdivided into stenotic and regurgitant lesions. Stenotic lesions have been characterized by anatomic location: supravalvar, valvar, and subvalvar. Regurgitant lesions have been characterized as either congenital or acquired. A comprehensive database set is presented that is based on a hierarchical scheme. Data are entered at various levels of complexity and detail that can be determined by the clinician. These data can lay the foundation for comprehensive risk stratification analyses. A minimum database set is also presented that will allow for data sharing and would lend itself to basic interpretation of trends. Outcome tables relating diagnoses, procedures, and various risk factors are presented. (C) 2000 by The Society of Thoracic Surgeons.
