Trombose Muito Tardia de Stent pela Angiografia. Um Caso de Progressão da Aterosclerose pela OCT

The progressive nature of coronary atherosclerotic disease is often neglected in patients submitted to percutaneous coronary intervention. Very late (> 1 year) myocardial infarctions affecting the treated myocardial territory are usually attributed to device related complications. We report the case of a patient with acute inferior wall ST-elevation myocardial infarction, who had a thrombotic occlusion of a bare-metal stent implanted 8 years before. Despite the angiographic diagnosis of very late stent thrombosis, optical coherence tomography revealed that the acute myocardial infarction was caused by rupture of an atherosclerotic plaque outside of the previously stented segment.
