Summary: | Forty healthy mongrel cattle hearts were examined for the presence of accessory cusps in the left atrioventricular valve. This study aimed to verify their presence and determine the number of leaflets in them, as well as suggest new cusp terminology. The hearts were fixed in 20% formalin and dissected. In this study, we observed the presence of 1 to 3 accessory cusps in both commissures of the main cusps; there was only a single case in which the cusps were absent. Since the presence of these cusps in cattle hearts has been verified, we suggest new terminology to describe these anatomical details that currently have no reference in the available literature.
Quarenta corações hígidos de bovinos sem raça definida foram examinados quanto à presença das cúspides acessórias na valva atrioventricular esquerda. Objetivou-se verificar sua presença, número de folhetos e indicar terminologia. Os corações foram fixados em formol a 20% e dissecados. Com a planificação da valva em estudo pôde-se observar que há presença de cúspides acessórias, variando de uma a três unidades, em ambas as comissuras das cúspides principais, com apenas um caso de sua ausência. Sugeriu-se terminologia para os detalhes anatômicos que não possuíam referência na literatura após busca atualizada. |
