Intravascular ultrasound assessment of ulcerated ruptured plaques: a comparison of culprit and nonculprit lesions of patients with acute coronary syndromes and lesions in patients without acute coronary syndromes.
BACKGROUND It is not clear why some plaque ruptures lead to acute coronary syndromes (ACS) but others do not. METHODS AND RESULTS We analyzed 80 plaque ruptures in 74 patients and compared culprit lesions of ACS patients with nonculprit lesions of ACS patients and lesions of non-ACS patients; both culprit and nonculprit plaque ruptures were studied in 6 of 54 ACS patients. Intravascular ultra...
متن کاملIncidence and clinical correlates of ruptured plaques in saphenous vein grafts: an intravascular ultrasound study.
OBJECTIVES The goal of this study was to assess the incidence, clinical correlates, and angiographic appearance of ruptured atherosclerotic plaques detected in saphenous vein grafts (SVGs). BACKGROUND Ruptured atherosclerotic plaques in native coronary arteries but not in SVGs have been well described with intravascular ultrasound (IVUS). METHODS We reviewed 791 pre-intervention IVUS SVG st...
متن کاملScreening of ruptured plaques in patients with coronary artery disease by intravascular ultrasound.
AIM To visualise the characteristics of ruptured plaques by intravascular ultrasound (IVUS) and to correlate plaque characteristics with clinical symptoms to establish a quantitative index of plaque vulnerability. METHODS 144 consecutive patients with angina were examined using IVUS. Ruptured plaques, characterised by a plaque cavity and a tear on the thin fibrous cap, were identified in 31 p...
متن کاملTissue 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 کاملAssessment of Non-Calcified Coronary Plaques Using 64-Slice Computed Tomography: Comparison With Intravascular Ultrasound
BACKGROUND AND OBJECTIVES Non-invasive detection and characterization of plaque composition may constitute an important step in risk stratification and monitoring of the progression of coronary atherosclerosis. Multislice computed tomography (MSCT) allows for accurate, non-invasive detection and characterization of atherosclerotic plaques, as well as determination of coronary artery stenosis. T...
