This international consensus provides a standardized nomenclature and classification system for congenital bicuspid aortic valves and associated aortopathies to unify clinical and research practices.
Answers are grounded in this paper and cite their sources.
Standardizes bicuspid aortic valve and aortopathy nomenclature; extends prior classifications to unify clinical decisions and research comparability.
This International Consensus Classification and Nomenclature for the congenital bicuspid aortic valve condition recognizes 3 types of bicuspid valves: 1. The fused type (right-left cusp fusion, right-non-coronary cusp fusion and left-non-coronary cusp fusion phenotypes); 2. The 2-sinus type (latero-lateral and antero-posterior phenotypes); and 3. The partial-fusion (forme fruste) type. The presence of raphe and the symmetry of the fused type phenotypes are critical aspects to describe. The International Consensus also recognizes 3 types of bicuspid valve-associated aortopathy: 1. The ascending phenotype; 2. The root phenotype; and 3. Extended phenotypes. © 2021 Jointly between the RSNA, the European Association for Cardio-Thoracic Surgery, The Society of Thoracic Surgeons, and the American Association for Thoracic Surgery.

Michelena et al. (2021) conducted a review in Congenital Bicuspid Aortic Valve and Its Aortopathy. Nomenclature and Classification Consensus was evaluated. This international consensus statement establishes a standardized nomenclature and classification system for congenital bicuspid aortic valves, recognizing fused, 2-sinus, and partial-fusion types.
