In some Transcatheter Aortic Valve Implantation (TAVI) procedures, difficulty in crossing the valve delivery system occurs. There are some described anatomical risk factors as extreme angulation, heavy calcification, and bicuspid morphology. A possible reason may be an unfavorable angle of approach because of the outward push by the incoming crimped bioprosthesis and insufficient support/trackability of the extra stiff wire. Several techniques and tips and tricks have been developed to overcome this problem and avoid procedure failure, as the “pull-and-push” technique, pre-dilation, buddy wire, balloon cushion, buddy balloon and the snare techniques. Here, we report a case of TAVI complicated by difficulty in crossing the calcified native aortic valve that was solved with the snare technique without complications.
