A: Use of the EchoNavigator Release I during Transcatheter Aortic Valve Replacement (TAVI) procedures. The hinge points of the aortic valve can be marked in the echo image and can then be transposed onto the X-ray image using the software. The gantry can then be turned into the direction in order to reach the line of perpendicularity of these three markers for proper valve implantation; B. After implantation of the Edwards bioprosthesis the exact position of the prosthesis can be seen as the radiolucent structure (white circle) within the copied echocardiographic anatomy of the aortic annulus.
