Journal of Biophysical Chemistry Study on the structure and composition of aortic valve calcific deposits: Etiological aspects

The structures and chemical compositions of valve calcific deposits were investigated. The deposits was chosen arbitrarily and subjected to chemical analysis, observation with scanning microscope, semi-quantitative determination of Ca, Mg, Na, K, P and C elements by energy dis-persive X-ray, X-ray diffraction and Fourier transform infra-red spectroscopy. These depos-its were found to have non-uniform internal structures composed of layers of a structureless aspidinic inorganic material, substantial amounts of voluminous organic material and in a few samples small spheres were also present. Two groups of deposits with distinctly differen
