ABSTRACT

For decades, angiography has been the gold standard for assessing the morphology and severity of atherosclerotic lesions in the coronary tree. Nevertheless, quantitative angiographic measurements can be deceptive, since this technique allows the assessment of only the shape of the lumen1. In turn, atherosclerosis is a disease of the vessel wall and, due to the compensatory expansive remodeling effect, the lumen area remains unaffected until final stages of the disease2.
