Fulltext PDFIn 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.
