A 49-year-old male smoker was admitted with chest pain and electrocardiographic T-wave inversion in the anterior chest leads and elevated levels of biomarkers of myocardial damage. Transthoracic echocardiography revealed anteroapical hypokinesis.

Coronariography showed normal coronary arteries. Therefore, based on electrocardiographic and wall-motion abnormalities, we selected the left anterior descending artery as the cause of the acute coronary syndrome and coronary imaging was performed.

Three-dimensional optical coherence tomography (3D-OCT) with angiographic co-registration was performed and an ulcerated small plaque covered by thrombus was observed (Figures 1-3; Videos 1-2). The amount of thrombus was not excessive and the minimal luminal area was 5.62 mm2, so a conservative management strategy was selected. The patient was asymptomatic at 6-month follow-up exam.

The OPTIS integrated system (St. Jude Medical) is a new technology allowing the online co-registration of OCT images with the angiogram in the catheterization laboratory.1 Additionally, 3D navigation can be performed.2,3 This integration of OCT information on an angiographic roadmap could find broad application in the characterization of substrates causing acute coronary syndromes with normal or near-normal coronary arteries. The utility of OCT with co-registration for the guidance of percutaneous coronary intervention could be considerable in the management of these patients.
