Novel Techniques to Crossing a Severely Stenotic Aortic Valve.

This report presents 2 cases with the use of different techniques to facilitate aortic valve crossing during transcatheter aortic valve replacement with a balloon-expandable system. Case 1 involves a balloon cushion technique with an Edwards Sapien 3 valve (Edwards Lifesciences), and case 2 describes successful crossing and implantation using a buddy balloon technique with an Edwards Sapien Ultra valve.
