Abstract
The interventionist treatment of chronic total occlusions has been one of the most complex procedures for interventionist cardiologists, especially since it is a procedure which frequently fails. However, in recent years there has been significant progress due to the creation of novel subintimal dissection and re-entry techniques, the adoption of the retrograde technique, and the design of organized flow charts which have allowed the conceptualization of the hybrid recanalization strategy for treating chronic total occlusions, achieving unprecedented success rates. This article reviews the available treatments for chronic total occlusions, based on the evidence, in an effort to unify concepts in terms of existing strategies.
