1. A stent of aortic valve that has three arms on the upper part and is self-expandable and repositionable, has two parts: the upper part and the lower part, wherein the lower part has a mesh distributed in such a way that it creates a kind of peripheral wall of the element, and the upper part of the stent has three arms derived from the mesh upwards and arranged at equal intervals, the height of which is greater than the height of the mesh, slightly less than the height of the mesh or equal to its height, wherein
at the end of each arm an upper tag is placed, characterized in that each upper tag (3) has its corresponding lower tag (8) wherein three upper tags (3) correspond to three lower tags (8) which are shifted by 60° from the upper tags (3) and
each lower tag (8) is placed on the lower edge (6) of membrane and—as if were in a top view—each lower tag (8) is visible halfway between the arms (2), wherein
each lower tag (8) is preferably different from others and can be seen with X-rays and wherein the upper tag (3) resembles in shape a spherical disk or small, low, almost flat cylinder with rounded edges or has a shape of a flat element of unique shape or is derived from the arm (2) and constitutes its curvature and additionally has characteristic holes or patterns.
