This review summarizes technical approaches, outcomes, and novel devices for percutaneous coronary intervention of chronic total occlusions, providing practical perspectives on patient management.
I n Part I of this article, the definitions, prevalence, and clinical presentation of chronic total occlusions (CTOs) were reviewed, the histopathology of CTOs was examined, efforts to replicate human CTOs with experimental models were appraised, and the clinical relevance and rationale for CTO revascularization were evaluated. 1In Part II, we summarize the technical approach to and outcomes after percutaneous coronary intervention (PCI) of occluded coronary arteries, describe the novel devices and drugs approved and undergoing investigation for CTO recanalization, and conclude with practical perspectives on managing the patient with 1 or more chronic coronary occlusions.
Stone et al. (Mon,) conducted a review in Chronic total occlusions (CTOs). Percutaneous coronary intervention (PCI) was evaluated. This review summarizes technical approaches, outcomes, and novel devices for percutaneous coronary intervention of chronic total occlusions, providing practical perspectives on patient management.
