Use of the Stingray® guidewire and the Venture® catheter for crossing flush coronary chronic total occlusions due to in‐stent restenosis

We report two cases of flush chronic total occlusion due to in‐stent restenosis, in which percutaneous coronary intervention attempts via over‐the‐wire balloons and microcatheters failed to cross the lesion. Using the Venture® catheter for support and the Stingray® guidewire for enhanced penetration capacity, both lesions were successfully crossed and stented. © 2010 Wiley‐Liss, Inc.
