The crista supraventricularis in the human heart and its role in the morphogenesis of the septomarginal trabecula.
The crista supraventricularis and septomarginal trabecula are common elements of the right ventricle, and determine many hemodynamic phenomena. The morphological analysis of both structures in regard to their mutual relations was the aim of this study. The study was carried out on the material of preserved human hearts--fetuses, children and adults. The size and development of the crista supraventricularis was carefully evaluated. The division of its lower part, and hence the possibilities of development of the septomarginal trabecula, was divided into five types (A, B, C, D and E). The most common was type B, containing two muscular trabeculae. The width of the crista varied 1/5-3/5 of the width of the interventricular septum. On the basis of this study, a conclusion of morphological unity of the septomarginal trabecula and crista supraventricularis was drawn.
