Percutaneous Coronary Intervention for Chronic Total Occlusion

Coronary chronic total occlusion (CTO), defined as complete occlusion of a coronary artery for at least 3 months with thrombolysis in myocardial infarction (TIMI) grade 0 flow, represents one of the most complex situations in the field of interventional cardiology.1 Despite an incidence of CTO in patients with stable coronary artery disease (CAD) undergoing coronary angiography of 18 –46%, the number of percutaneous coronary interventions (PCIs) for CTO is still less than 4% of all percutaneous revascularizations.
