Special Issue Introduction
Coronary chronic total occlusion (CTO) is defined as TIMI (Thrombolysis In Myocardial Infarction) grade 0 flow within the occluded segment, with an occlusion duration greater than three months. The occlusion duration is divided into three levels of certainty as follows: a) “certain”(angiographically confirmed), in case where a previous angiogram confirmed the presence of a CTO greater than three months prior to the planned procedure; b) “likely” (clinically confirmed), objective evidence of an acute myocardial infarction (MI) in the territory of the occluded artery without other culprit arteries of more than three months before the current angiogram; c) “undetermined”, a TIMI 0 flow and angiographic anatomy suggestive of a long-standing occlusion with stable symptoms unchanged in the last three months or evidence of silent ischaemia.
CTOs are frequently, in approximatively 15-20% of patients undergoing coronary angiography. This CTO prevalence is even higher (> 50%) among patients with prior coronary artery bypass graft (CABG). The right coronary artery represents the most commonly involved vessel.
Although CTO was previously considered to be a strong predictor of incomplete revascularization, thanks to the recent development of equipment and techniques in addition to the growing expertise among operators, high success rates of CTO PCI have been achieved with low rates of complications.
The objectives of the current special issue are the following :
-to discuss clinical indications of CTO recanalization and recent data reported in literature
-to report the trends in CTO PCI material and techniques
-to focus on CTO PCI in particular settings and how to manage complications
