Development and arterial supply of the supraventricular crest during the human embryonic and fetal periods

Acta Anat (Basel). 1988;132(2):143-9. doi: 10.1159/000146566.


Several works have concerned themselves with the anatomy of the supraventricular crest, for example, analyzing its role in the physiology of the right ventricle; nevertheless, its structure and arterial supply have been less studied. We have studied the morphogenesis of the architecture and the arterial supply of the supraventricular crest, in 25 embryos and human fetuses of 13-71 mm crown-rump length. The muscular organization of the crest (proper muscular bundles and parietal bundles of the right ventricle) and the development of the supraventricular crest's artery as well as its trajectory and its distribution during the fetal period were examined.
