Congenital Heart Surgery Nomenclature and Database Project: right ventricular outflow tract obstruction-intact...

The extant nomenclature for pulmonary atresia/stenosis with intact ventricular septum, pulmonary artery and/or pulmonary branch stenosis, double chambered right ventricle, absent pulmonary valve with intact ventricular septum, and ventricular to pulmonary artery conduit failure 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. Multiple risk factors were considered such as coronary artery fistulas/sinusoids, tricuspid annular size and location of peripheral pulmonary artery stenoses. A comprehensive database set is presented which is based on a hierarchical scheme. Data are entered at various levels of complexity and detail which can be determined by the clinician. These data can lay the foundation for comprehensive risk stratification analyses. A minimum database set is also presented which will allow for data sharing and would lend itself to basic interpretation of trends. Potential diagnostic related risk factors for each lesion are presented.
