Percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) presents unique challenges and potential complications. The two most common failure modes are inability to cross the lesion with a guidewire and failure to cross the CTO with a balloon after successful guidewire crossing ("balloon-uncrossable" CTO). We present a creative solution to assist crossing of balloon-uncrossable CTOs that entails use of a balloon placed over a wire that has been advanced though the subintimal space to anchor the guidewire that has crossed through the CTO true lumen enabling lesion crossing with a balloon.
