Y1 - 2017 N1 - T2 - Interventional Cardiology, 2e AB - A coronary artery chronic total occlusion (CTO) is defined as an occlusion present for 3 or more months, which will feature classic histopathologic changes (Fig. 35-1). Although considered separately in this book, the treatment decisions for coronary revascularization should focus on coronary physiology and ischemia rather than specific anatomic considerations. To that end, the indications for treatment of CTOs should be indistinguishable from 95% coronary lesions. However, once the decision to treat a CTO percutaneously is chosen, the technical aspects of this treatment diverge significantly from standard coronary intervention. For many interventionalists, CTOs continue to represent a major technical challenge.
