[The use of biological cardiac valve prostheses in modern cardiosurgery]
Abstract:
The present review is devoted to the problem of bioprosthetics of cardiac valves with special reference to its methodological and technological aspects including peculiarities of the most extensively used varieties of biological prostheses, current tends in the choice of indications for their application in the treatment of various congenital valvular diseases and for their implantation to the specific groups of patients. The main causes and mechanisms underlying structural degradation of bioprostheses depending on the technological processes of their manufacture and the patterns of calcium salt accumulation in the fixed tissues are considered Physiological consequences and delayed results of bioprosthetics are discussed.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
