[Study of functional parameters of prosthetic cardiac valves]

A set of methods is offered, which enables to examine, with more details, the functional characteristics of the valves and to analyze them comparatively. The thus obtained functional characteristics make it possible to compare the valves and to select the best one prior to implantation. The results of a clinical study of the functioning of a valve, implanted by a new method involving a high-sensitivity solid sensor, are described.
