Current research shows that some of the pathogenetic processes behind structural destruction of bioprosthetic valves are largely similar to those involved in the development of atherosclerotic vascular lesions and native valve calcification. These pr

Bioprosthetic valves are often used to replace diseased heart valves. They differ from mechanical valves by optimal hemodynamic parameters and low thrombogenicity. However, although the durability of modern bioprosthetic valves, their design, and imp
