Chronic total occlusions (CTO) of the coronary arteries are a common finding. A CTO can be underdiagnosed on CT coronary angiography (CTCA) as a high grade stenosis, because of the presence of retrograde collaterals which allow opacification of the vessel distal to the stenosis, or can be missed completely, especially if another adjacent opacified artery is mistaken for occluded artery. CTOs are considered as Type C or high risk lesions with a higher restenosis rate and increased technical… CONTINUE READING
