Abstract

Chronic total occlusion (CTO) intervention constitutes approximately 10–20% of all angioplasty procedures at selected centers. Benefits of CTO revascularization, in addition to relief of angina, include improvement of left ventricular function, reduced risk of major adverse cardiac events and potentially increased survival. Although several techniques, devices and guidewires have been developed for use in CTO, leading to an increased success rate, limitations of angiography in visualizing occluded arteries makes CTO interventions technically challenging. This article focuses on the principle intracoronary imaging techniques, such as intravascular ultrasound and optical coherence tomography, that may provide guidance during CTO revascularization, improving procedure timing, safety and efficacy.
