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

Popis výsledku v původním jazyce

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 Celements by energy dis-persive X-ray, X-ray diffraction and Fourier transform infra-red spectroscopy carried out. These deposits 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 different chemical compositions were identified: one group with a low Ca/P molar ratio (1.59) and the other group with a high (1.82) Ca/P molar ratio. The deposits belonging to the group with a low Ca/P molar ratio contain higher concentra-tion of magnesium and consist of increased amount of amorphous calcium phosphate. The deposits with a high Ca/P m
