Morphological and Chemical Study of Pathological Deposits in Human Aortic and Mitral Valve Stenosis: A Biomineralogical Contribution

<div>BSE-SEM analyses of PTS (sample Tv20ab). (a) High magnification image of a micrometric nodule formed by two different stages of mineralization. The lower zone of the nodule having lower brightness had greater content of C and S (spot a) (b) than the upper zone of the nodule (spot b) (c). This indicates a partially mineralized organic matrix for the lower zone of the nodule and a fully mineralized tissue for the upper zone.</div>
