Intravascular ultrasound assessment of fibrous cap remnants after coronary plaque rupture
American Heart Journal, 2006Although intravascular ultrasound (IVUS) can detect plaque rupture, the fibrous cap remnant has not previously been studied in detail. The aim of the present study is to assess the fibrous cap remnants by IVUS in ruptured plaques.In 53 patients, a ruptured plaque with a fibrous cap remnant was studied by IVUS.In 36 (68%) patients, the rupture of the ...

Semi-automated Quantification of Fibrous Cap Thickness in Intracoronary Optical Coherence Tomography
International Conference on Information Processing in Computer-Assisted Interventions, 2014Acute coronary syndrome represents a leading cause of death. Events are triggered by rupture of atheromatic plaques, as a result of disruption of the overlying fibrous cap. Pathological studies have shown that cap thickness is a critical component of plaque stability.

Three‐dimensional imaging of fibrous cap by frequency‐domain optical coherence tomography
Catheterization and Cardiovascular Interventions, 2013Histopathological data correlated the presence of thin‐cap fibroatheroma (TCFA) with adverse cardiovascular events. Intravascular optical coherence tomography (iOCT) is currently the only imaging modality with sufficiently high axial resolution (∼15 μm) that allows direct fibrous‐cap (FC) assessment in vivo.

Acute Coronary Syndrome: Ruptured and Intact Fibrous Caps
2017Coronary thrombosis is the most common cause of acute coronary syndromes (ACS), including sudden cardiac death. Plaque rupture in most cases, plaque erosion uncommonly, and calcified nodule rarely have been demonstrated to be the main mechanisms underlying acute coronary thrombosis in both ex vivo and in vivo studies.

Experimental measurement of the mechanical properties of carotid atherothrombotic plaque fibrous cap
Journal of Biomechanics, 2009Eleven carotid atherothrombotic plaque samples were harvested from patients. Three samples that were highly calcified were discarded, while eight yielded results. The elastic properties of the material were estimated by fitting the measured indentation response to finite element simulations. The methodology was refined and its accuracy quantified using

Measurement of the thickness of the fibrous cap by optical coherence tomography
American Heart Journal, 2006Identification of the fibrous cap is important because its thickness is a major determinant of plaque vulnerability in lipid-rich plaque. Thus, a high-resolution imaging technique may be a promising method for the identification of the fibrous cap within lipid-rich plaque.

Investigation of fibrous cap stresses on vulnerable plaques leading to heart attacks
Technology and Health Care, 2015Rupture-prone plaques in the coronary arteries, called ``vulnerable plaques'', are recognized as the key factor in acute myocardial infarction. Vulnerable plaques have a thin fibrous cap over a large fatty core and are highly susceptible to rupture. In general, this type of plaque rupture is mainly associated with stress concentrated on the fibrous cap.
