  • Eu acredito que a descrição deva ser de Valva Bivalvular e não trivalvular. A presença da RAFE, que é a fusão comissural, é característica da patologia valvar. A sua ausência ocorre na minoria das vezes. Portanto, acabaríamos descrevendo a maioria das valvas bivalvulares como tri ou bi-tri!

    “The bicuspid valve is typically made of 2 unequal-sized leaflets. The larger leaflet has a central raphe or ridge that results from fusion of the commissures, and these fused commissures are susceptible to disruption as occurs with balloon valvuloplasty. The morphologic patterns of the bileaflet valve vary according to which commissures have fused, with the most common pattern involving fusion of the right and left cusps. Fusion of the right and left coronary cusps is associated with coarctation of the aorta. Fusion of the right and noncoronary cusps is associated with cuspal pathology. Rarely, the leaflets are symmetrical or there is no raphe (“pure” bicuspid valve). A number of classifications have been used that pertain to the orientation of the leaflets”
