摘要： An artificial cardiac valve made of biocompatible material comprises an annular element (1) and a flap (2) pivotally lodged inside said element (1) and possessing linking elements for cooperating with guiding and restraining means provided on the internal side wall (4) of the annular element (1). The flap (2) consists of a disc folded along an axis XX' parallel to one of its diameters through an angle alpha between 0 and 30 DEG in such a way that the opening of the valve is effectued in two consecutive phases. The first phase corresponds to a rotation of the flap (2) about the contact and hinging point A between the rear part (3) of the flap (2) and the lower edge of the side wall of said element until said linking elements abut against the guiding and restraining means. The second phase corresponds to a rotation about an axis ZZ' parallel to the axis XX' until the rear part (3) of the flap (2) is parallel to the axis YY' of the element (1).
