Chronic total occlusions of coronary arteries: morphology, pathophysiology, technique of recanalization

Abstract

Percutaneous coronary intervention (PCI) for chronic total occlusions of coronary arteries (CTO) is a rapidly evolving field of interventional cardiology. Recanalization of the coronary arteries is a technically difficult intervention. The most common cause of unsuccessful recanalization of a CTO is failure to cross intracoronary wire the proximal and distal caps of a CTO. Over the past few years in order to understand the morphology and pathophysiology CTO’s the investigations which has been developed and put into practice a specialized tool and techniques for recanalization of the CTO. In this article, based on clinical studies overview of the most effective stents in CTO, with low restenosis rate.
