Can a novel echocardiographic tricuspid valve nomenclature classification scheme identify different TV morphologies using TEE imaging?
A novel TEE-based classification scheme reveals that only about half of patients have the classic 3-leaflet tricuspid valve, while nearly 40% have 4 functional leaflets.
A novel TV leaflet nomenclature classification scheme can be used to identify 4 types of TV morphologies with the use of TEE imaging. From this multinational retrospective study, the TV has 3 well defined leaflets in only ∼54% of patients and 4 functional leaflets in ∼39% of patients, with type IIIB (2 posterior leaflets) being the most common of the latter. The utility of this classification scheme deserves further study.
Hahn et al. (Thu,) studied this question.
