A PICKING technique: percutaneous intravascular cracking with a guidewire tail, which indicated longitudinal repeated cracking of the calcified lesion by a stiff tail of a guidewire with the parallel-wire method under fluoroscopy guidance, was previously reported to make balloon catheter delivery easier for severely calcified lesions [1, 2]. However, this technique might have some problems as follows: (1) a potential risk of vessel perforation mainly because of the poor fluoroscopic visibility of the guidewire tail; and (2) poor handling of its direction, etc.

A 74-year-old woman with intermittent claudication was referred to our hospital. Diagnostic angiography revealed extremely calcified chronic total occlusions (CTOs) in both ostial superficial femoral arteries (SFAs) (Fig.  1a). No stiff wire, such as a 100-g tip-load 0.014-in. guidewire, could pass the calcification retrogradely in the right SFA. Given a TruePath™ (Boston Scientific, Natick, Massachusetts), which consists of a...
