Artificial cardiac or venous valve for placement in veins and/or arteries external to the heart, in place of the venous valve or in series with the damaged cardiac, consisting of a check valve constituted by a cylindrical tubular element in whose inside carries shutter elements consisting of two fins or blades which oscillate longitudinally around an arranged support or shaft and transverse and diametrically held in the center of said tubular elements, producing the opening and closing of the valve, and thereby the circulation in a sense or cut of the blood flow when pressed or sucked by it, preventing its recoil when the pressure or suction ceases, joining and adapting the leaves laterally to the interior of the tubular element.
