NOBILE, Natalia; MILA, Rafael  e  BACHINI, Juan Pablo. Utility of optical coherence tomography to guide treatment in acute coronary syndromes. Case report. Rev.Urug.Cardiol. [online]. 2023, vol.38, n.1, e702.  Epub 01-Dez-2023. ISSN 0797-0048.  https://doi.org/10.29277/cardio.38.1.14.

Optical coherence tomography (OCT) is an endovascular imaging technique with high spatial resolution. It allows to evaluate the different structures that compose coronary arteries’ wall, morphologically characterize atherosclerotic plaques and establish the underlying pathophysiological mechanism in acute coronary syndromes (ACS). The case of a patient with acute myocardial infarction is presented, in which OCT showed that the reduction of arterial lumen was determined mainly by the presence of thrombus, while also demonstrated endothelial disruption (plaque rupture) as the underlying pathophysiological mechanism. An invasive-conservative strategy was adopted and finally stent was not implanted. The information that emerged from the OCT in this particular case was fundamental in decision-making.
