A patient was referred for PCI of a right coronary artery subtotal lesion after failure to cross the lesion with a guidewire. The lesion was eccentric and heavily calcified. Antegrade wiring with a microcatheter and polymer-jacketed (Fielder XT-A, Sion black) and intermediate tip stiffness (Gaia Next 2) guidewires failed. A Sion black was advanced into an acute marginal branch at the proximal cap followed by “open sesame” without success. Eventually a Gladius Mongo wire was advanced across the mid RCA lesion in the extraplaque space, followed by re-entry into the distal true lumen using the Stingray balloon and the “stick and swap” technique. A nice result was achieved after stenting both angiographically and by IVUS (the stent had oval shape at the calcified vessel segment).
