[Age-dependent dynamics of biomechanical and hydrodynamic properties of the valve-aortic complex of man].
A comparative analysis of geometrical, biomechanical and hydrodynamic characteristics of the valve-aortic complexes taken from humans of different age has shown a determining role of distensibility of the aortic root in the functioning of valve cusps. An alteration of geometrical relationships of elements of the aortic root, its less distensibility, worse biomechanical and hydrodynamic characteristics of the aortic valve in humans older than 50-60 years of age is established.
