Multi-Detector Computed Tomography versus Invasive Coronary Angiography for Guiding Percutaneous Coronary Intervention in Chronic Total Occlusion

Abstract

TO lesions represent the last frontier for coronary interventionist and are still considered frequent reason for referring patients for CABG. CTO intervention is proven to be a complex procedure with a variable success rate between 55 and 80% in most experienced centers, high success rates are usually observed in a few luminary sites. This procedure results in different complications including dissection, perforation and impairment of ipsilateral collaterals to the distal bed. Also it is associated with a considerable rate of major adverse coronary event (MACE).
