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.
