Aortic Valve Replacement for Calcified Aortic Valves

Mycoplasma pneumoniae and Chlamydia pneumoniae in calcified nodules of aortic stenotic valves.

Aortic Valve Stenosis (AVS) has been explained as an atherosclerotic process of the valve as they often exhibit inflammatory changes with infiltration of macrophages, T lymphocytes and lipid infiltration. The present study investigated whether the bacteria Chlamydia pneumoniae (CP) and Mycoplasma pneumoniae (MP), detected previously in atherosclerotic plaques, are also present in AVS. Ten valve...

Tomography of calcified aortic and mitral valves.

The purpose of this paper is to compare the value offluoroscopy and tomography in distinguishing aortic from mitral valve calcification. In view of this difficulty, certain criteria are recorded to aid their identification. Aortic valve calcification was first described in 1672 by Rayger (quoted by Bonetus, 1679). Eighty-two years later, Morgagni recorded a patient dying in cardiac failure who ...

Surface topography of stenotic aortic valves by scanning electron microscopy.

Surface features of 19 stenotic aortic valves from patients undergoing valve replacement were investigated by scanning electron microscopy. Villi, prominent on five valves, were distributed either singularly or in clusters and differed in shape. Endothelial cells had microvilli and bulbous surface projections. Endothelial disruption with a focal loss of endothelial cells was uniformly observed...
