Summary

An anatomical study of the tricuspid valve was carried out in 50 human hearts of both female and male individuals using a method of dissection which preserves the integrity of the valve. Morphometric criteria such as area of cusp, width of cusp base, relation between commissure depth and cusp depth and morphological criteria such as the presence of atrioventricular cusp node, number of tendinous cords, perimeter of fibrous ring, and properties of papillary m. were adopted for characterization of a cusp. In 64% of cases, commissural cusps were present independent of the number of tricuspid cusps. The tricuspid valve was not consistently tricuspid, but was observed to present 2, 4, 5 or 6 cusps in 72% of cases.

Etude anatomique de la valve atrio-ventriculaire droite chez l'homme

Résumé

Les auteurs ont réalisé une étude anatomique de la valve atrio-ventriculaire droite sur 50 cœurs humains des deux sexes — à partir d'une méthode de dissection qui préserve l'intégrité de cette valve. Ils ont utilisé des critères morphométriques (surface de la cuspide, largeur de la base de cette cuspide, rapport entre la profondeur de la commissure et la profondeur de la cuspide), et aussi des critères morphologiques (présence de nodule sur la cuspide atrio-ventriculaire, nombre de cordages tendineux, périmètre de l'anneau fibreux et qualité des muscles papillaires) pour une caractérisation adéquate des cuspides. Dans 64 % des cas, une valvule avec ses commissures propres était présente indépendamment des trois cuspides de la valve atrio-ventriculaire droite. Cette valve n'était pas toujours tricuspide, mais présentait 2, 4, 5 ou 6 valvules dans 72 % des cas.
