    Abstract: A method for rotationally aligning a valve prosthesis using imaging identifiers includes delivering the valve prosthesis in a collapsed configuration in a catheter to a vicinity of a functioning native heart valve of a heart of the subject using a retrograde approach, generating an image of the functioning native heart valve and the valve prosthesis, rotationally aligning engagement arms of the valve prosthesis with sinuses of the functioning native heart valve using at least one of the imaging identifiers of the heart valve prosthesis visible in the image.

    Abstract: A prosthesis is provided for implantation at a native semilunar valve of a native valve complex, the native valve complex having three semilunar sinuses and three native commissures. The prosthesis includes a valve prosthesis support, which comprises a support structure comprising exactly three engagement arms that meet one another at three respective junctures. The engagement arms are shaped so as define three peak complexes at the three respective junctures, and three trough complexes, each of which is between two of the peak complexes. Upon implantation of the prosthesis, each of the engagement arms is at least partially disposed within a respective one of the semilunar sinuses, such that each of the peak complexes is disposed distal to and in rotational alignment with a respective one of the native commissures, and each of the trough complexes is disposed at least partially within the respective one of the semilunar sinuses.
