Case 155: Manual of CTO PCI - Balloon uncrossable CTO

A patient was referred for PCI of an LAD CTO. Antegrade crossing attempts failed. Retrograde crossing was successful using a Caravel microcatheter with true to true wire crossing into the proximal true lumen with a stiff tip guidewire. The lesion could not be crossed by a microcatheter or balloon despite using small balloons (1.0 mm Sapphire Pro and Threader), a guide catheter extension, various microcatheters and laser. Eventually the retrograde position was lost. Antegrade dissection/re-entry was successful in crossing the CTO using a Stingray balloon with the bobsled and double blind stick and swap techniques, with a nice final result after stenting.
