The field of percutaneous intervention for chronic total occlusion (CTO) has enjoyed significant
innovations in the recent years. Novel techniques and technologies have revolutionized the
field and have resulted in considerably higher success rates even in patients with high anatomical
complexity. Successful CTO recanalization is associated with significant clinical benefits, such as the
improvement of angina and quality of life, reduced rates of surgical revascularization, improvement of
left ventricular function and decreased mortality rates. However, complex CTO procedures often require
prolonged x-ray exposure which have been associated with adverse long term outcomes.
