Impact of coronary artery remodeling on clinical presentation of coronary artery disease: an intravascular ultrasound study.
OBJECTIVES We examined the association between the features of the culprit lesion in coronary artery disease (CAD) and clinical presentation as shown by intravascular ultrasound (IVUS). BACKGROUND The association between coronary remodeling pattern and clinical presentation of CAD is unclear. METHODS We analyzed 125 selected patients who underwent preintervention IVUS. Acute myocardial infa...
متن کاملComparison of intravascular ultrasound and quantitative coronary angiography for the assessment of coronary artery disease progression.
BACKGROUND The relative merits of quantitative coronary analysis (QCA) and intravascular ultrasound (IVUS) for the assessment of progression/regression in coronary artery disease are uncertain. To explore this subject further, we analyzed the angiographic and IVUS data derived from a contemporary clinical trial population. METHODS AND RESULTS We investigated the relationships between QCA and ...
متن کاملDeterminants of coronary remodeling in transplant coronary disease: a simultaneous intravascular ultrasound and Doppler flow study.
BACKGROUND Coronary remodeling plays a significant role in lumen loss in transplant allograft vasculopathy (TxCAD), but the determinants of remodeling are unknown. We assessed the relationship between remodeling and plaque topography, coronary compliance, and blood flow in TxCAD. METHODS AND RESULTS One artery in each of 27 transplant patients was investigated with simultaneous intravascular ...
متن کاملCoronary artery imaging with intravascular high-frequency ultrasound.
Safe and effective clinical application of new interventional therapies may require more precise imaging of atherosclerotic coronary arteries. To determine the reliability of catheter-based intravascular ultrasound as an imaging modality, a miniaturized prototype ultrasound system (1-mm transducer; center frequency, 25 MHz) was used to acquire two-dimensional, cross-sectional images in 21 human...
متن کاملUnderstanding coronary artery disease: tomographic imaging with intravascular ultrasound.
In 1856 the pathologist Virchow published his now classic observations on atherothrombosis based on the examination of postmortem tomographic artery sections. The Virchow triad describes three components contributing to the atherothrombotic disease process: the vessel wall, the blood constituents, and blood flow. In vivo coronary imaging techniques became available more than 100 years later wit...
