Coronary plaque ulceration documented at sequential angiography and confirmed by optical coherence tomography in a patient with recurrent acute coronary syndrome

A 51-year-old man was hospitalized for recurrence of acute coronary syndrome after few months. Coronary angiography during first hospitalization showed no significant coronary stenosis, while the second time, right coronary artery presented an expansion at the proximal segment. Optical coherence tomography documented a long fibroatheroma with an ulceration and residual white thrombus.
