Imaging of the Fibrous Cap in Atherosclerotic Carotid Plaque
CardioVascular and Interventional Radiology, 2010In the last two decades, a substantial number of articles have been published to provide diagnostic solutions for patients with carotid atherosclerotic disease. These articles have resulted in a shift of opinion regarding the identification of stroke risk in patients with carotid atherosclerotic disease. In the recent past, the degree of carotid artery

Mechanisms of Vascular Atrophy and Fibrous Cap Disruption
Annals of the New York Academy of Sciences, 2000Abstract: The process of plaque destabilization and rupture remains an area of intense investigation. While reductions in lumen cross‐sectional area induced by early, non‐occlusive lesions are compensated by remodeling and expansion of the artery, further plaque enlargement leads to an uncompensated reduction in lumen area and an increase in surface ...

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.

Microcalcifications, Their Genesis, Growth, and Biomechanical Stability in Fibrous Cap Rupture
2018For many decades, cardiovascular calcification has been considered as a passive process, accompanying atheroma progression, correlated with plaque burden, and apparently without a major role on plaque vulnerability. Clinical and pathological analyses have previously focused on the total amount of calcification (calcified area in a whole atheroma cross ...

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

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.

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.

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 ...
