Key result
The Venture catheter and Stingray guidewire successfully crossed and stented two flush chronic total occlusions due to in-stent restenosis after standard balloons and microcatheters failed.
Why the study?
Does the use of the Stingray guidewire and Venture catheter enable successful crossing of flush coronary chronic total occlusions due to in-stent restenosis?
Does the use of the Stingray guidewire and Venture catheter enable successful crossing of flush coronary chronic total occlusions due to in-stent restenosis?
The combination of the Venture catheter and Stingray guidewire can be successfully used to cross flush chronic total occlusions due to in-stent restenosis when standard techniques fail.
May aid bailout crossing of refractory flush ISR-CTOs; hypothesis-generating and requires prospective validation.
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.
