Abstract
The cardiac valve comprises an annular body, at one end of which there are pivoted valve members, adapted to operate as a closing element, the annular body consisting of an outer ring member and an inner ring member which are mutually coupled, one of the ring members defining the pivot seats of the valve members, whereas the other ring member is adapted to delimit these seats, in order to provide a stable pivoting coupling of the valve members to the annular body.
