Tissue Characterization of Coronary Plaques Using Intravascular Ultrasound/Virtual Histology
Most studies related with plaque histopathology and/or morphology are based on the gray scale intravascular ultrasound (IVUS) and autopsy findings, although IVUS is limited for differentiating echolucent areas, and tissue shrinkage almost always occur during tissue fixation. In addition, autopsy studies can not establish the causal relationship between the autopsy findings and the clinical find...
متن کاملCoronary plaque classification with intravascular ultrasound radiofrequency data analysis.
BACKGROUND Atherosclerotic plaque stability is related to histological composition. However, current diagnostic tools do not allow adequate in vivo identification and characterization of plaques. Spectral analysis of backscattered intravascular ultrasound (IVUS) data has potential for real-time in vivo plaque classification. METHODS AND RESULTS Eighty-eight plaques from 51 left anterior desce...
متن کاملCoronary intravascular ultrasound.
C oronary angiography remains an important modality for assessing atherosclerotic coronary artery disease and guiding percutaneous coronary intervention. Intravascular ultrasound (IVUS) is an important adjunct during coronary angiography and has been increasingly used in clinical and research applications in the past decade. It has vastly enhanced our understanding and has provided us with a th...
متن کاملPrediction of the localization of high-risk coronary atherosclerotic plaques on the basis of low endothelial shear stress: an intravascular ultrasound and histopathology natural history study.
BACKGROUND Low endothelial shear stress (ESS) promotes the development of atherosclerosis; however, its role in the progression of atherosclerotic plaques and evolution to inflamed high-risk plaques has not been studied. Our hypothesis was that the lowest values of ESS are responsible for the development of high-risk coronary atherosclerotic plaques associated with excessive expansive remodelin...
متن کاملCharacterization of coronary plaques with combined use of intravascular ultrasound, virtual histology and optical coherence tomography
According to post-mortem studies, luminal thrombosis occurs from plaque rupture, erosion and calcified nodules. In vivo studies have found thin cap fibroatheroma (TCFA) as the main vulnerable lesion, prone to rupture. Few data about other post-mortem lesions have been reported in vivo. Our main objective is to characterize in vivo the coronary plaques with intravascular ultrasound-virtual histo...
