A patient with medically refractory angina was referred for PCI of an LAD CTO. The CTO had a blunt and calcified proximal cap, length of about 15-30 mm, diffusely diseased and calcified distal vessel that was filling via an ipsilateral epicardial collateral. Antegrade wiring attempts with a Gaia Next 2 and 3 and a Hornet 14 resulted in extraplaque wire advancement. The epicardial collateral was successfully crossed with a Suoh 03 wire but the Caravel microcatheter could not reach the CTO (a 100 cm long guide was used). A Gladius Mongo wire was advanced into the antegrade guide catheter where it was “tipped in” an antegrade Corsair XS microcatheter. The Corsair XS was advanced across the CTO followed by insertion of an antegrade wire, intravascular lithotripsy and stenting with a nice final result.
