Evaluation of atherosclerotic plaque composition and morphometry may yield insight into plaque biology and the mechanisms of plaque-associated thrombosis. Analysis of intravascular ultrasound radiofrequency (IVUS-RF) backscatter signal is one technology that provides in vivo assessment of both atherosclerotic plaque composition and morphometry. We summarize three different approaches to IVUS-RF...
Stent under expansion is one of the reasons compromising outcomes percutaneous coronary interventions. The most common cause stent calcium deposited in atherosclerotic plaque. Adequate plaque modification paramount before placement a stent, as options to handle expanded are limited and less effective. In this case report, we explore usage knuckle wire for extrastent modification, after being fa...
BACKGROUND The Rustogi et al. Modified Navy (RMNPI) and Turesky et al Modification of the Quigley Hein (TQHPI) plaque indices are commonly used to measure plaque removal. This study evaluated the possible correlations of both indices using data relative to a single use assessment of plaque removal using commercially available toothbrushes. METHODS Single use crossover study designs have been ...
AIMS To evaluate the relationship between lipid content and plaque morphometry as well as the process of lesion progression and regression in patients with significant coronary artery disease. METHODS AND RESULTS The present study, using data from the YELLOW trial, was conducted in patients having significant coronary lesions (fractional flow reserve <0.8) who underwent serial intravascular u...
BACKGROUND Computed tomography (CT) is used routinely for coronary angiography, and higher-risk features of plaques can also be identified. However, the ability of CT to discriminate individual plaque components and classify plaques according to accepted histological definitions is unknown. METHODS AND RESULTS We first determined CT attenuation ranges for individual plaque components using co...
Plaque 'calcium-fluoride-like' (CaF(2)-like) and fluoride deposits held by biological/bacterial calcium fluoride (Ca-F) bonds appear to be the source of cariostatic concentrations of fluoride in plaque fluid. The aim of this study was to quantify the amounts of plaque fluoride held in these reservoirs after a sodium fluoride rinse. 30 and 60 min after a 228 microg/g fluoride rinse, plaque sampl...
BACKGROUND AND AIMS In a large stroke-free population, we sought to identify cardiovascular risk factors and carotid plaque components associated with carotid plaque burden, lumen volume and stenosis. METHODS The carotid arteries of 1562 stroke-free participants from The Rotterdam Study were imaged on a 1.5-Tesla MRI scanner. Inner and outer wall of the carotid arteries were automatically seg...
