title: Successful recanalization of in-stent coronary chronic total occlusion by subintimal tracking.
abstract: Percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) caused by in-stent restenosis (ISR) is sometimes very difficult due to the presence of hard occlusive components that prevent wire passage. We report a case of CTO caused by ISR (ISR-CTO) in which the occlusion was crossed with the wire subintimally along the outside of the stent and was successfully re-stented. Subintimal tracking along the outside of the stent can be considered as another approach for PCI of ISR-CTO in cases where conventional approaches fail.
