    1. OCT Assessment of Thin-Cap Fibroatheroma Distribution in Native Coronary Arteries

      OCT Assessment of Thin-Cap Fibroatheroma Distribution in Native Coronary Arteries

      Objectives We evaluated the geographic distribution of thin-cap fibroatheromas (TCFAs) in the coronary arteries using optical coherence tomography (OCT), a high-resolution imaging modality. Background Plaque rupture is the most frequent cause of acute myocardial infarction (AMI). It has been recognized that TCFA is the primary plaque type at the site of plaque rupture. Methods We performed 3-vessel OCT examinations in 55 patients: 35 AMI and 20 stable angina pectoris patients. The criteria for TCFA in an OCT image was a lipid-rich plaque with fibrotic cap thickness <65 µm. The distance between each TCFA location and the respective coronary artery ostium ...

      Frequency and Predictor of Coronary Thin-Cap Fibroatheroma in Patients With Acute Myocardial Infarction and Stable Angina Pectoris: A 3-Vessel Optical Coherence Tomography Study

      (A) A 90% stenosis observed in the middle left anterior descending artery in patients with stable angina pectoris (arrow). (B) Lipid-rich plaque (L) covered by thin fibrous cap (63.3 µm) (arrowheads) observed in the target lesion of a patient with stable angina pectoris. (C) Lipid-rich plaque (L) covered by thin fibrous cap (arrowheads) detected in the noninfarct-related lesion of an acute myocardial infarction patient. (D) Magnification of (C). The thickness of the fibrous cap that existed betw
