Features of disrupted plaques by coronary computed tomographic angiography: correlates with invasively proven complex lesions.
BACKGROUND This study was designed as a "proof-of-concept" to establish whether coronary computed tomographic angiography (CTA) has the capability to identify morphological features of plaque disruption. METHODS AND RESULTS In patients with unstable angina undergoing CTA and invasive coronary angiography within 30 days, quantitative CTA analysis was performed on all plaques for percent stenos...
متن کاملComputed tomographic angiography characteristics of atherosclerotic plaques subsequently resulting in acute coronary syndrome.
OBJECTIVES In a computed tomographic (CT) angiography study, we identified the characteristics of atherosclerotic lesions that were associated with subsequent development of acute coronary syndrome (ACS). BACKGROUND The CT characteristics of culprit lesions in ACS include positive vessel remodeling (PR) and low-attenuation plaques (LAP). These 2 features have been observed in the lesions that...
متن کاملCharacteristics of high-risk coronary plaques identified by computed tomographic angiography and associated prognosis: a systematic review and meta-analysis.
To clarify the potential role of coronary computed tomographic angiography (CCTA) in characterizing and prognosticating high-risk coronary plaques. A systematic review and meta-analysis were conducted to compare high-risk vs. low-risk plaques and culprit vs. non-culprit lesions in patients with acute coronary syndrome (ACS) vs. stable angina (SA). High-risk plaques were defined by at least one ...
متن کاملAnatomy of an emerging diagnostic test: computed tomographic coronary angiography.
The study by Mollet et al on CT coronary angiography in this issue of Circulation is important for several reasons.1 The 64-multislice technology for acquiring tomographic x-rays of the coronary vessels during the arterial phase of a bolus of iodinated contrast introduces several technical advances: improved spatial resolution (thinner slices), improved temporal resolution (less time needed to ...
متن کاملDiagnostic accuracy and impact of computed tomographic coronary angiography on utilization of invasive coronary angiography.
BACKGROUND Computed tomographic coronary angiography (CTA), given its high negative predictive value, is a potential gatekeeper for invasive coronary angiography (ICA). Before CTA can be further accepted into clinical practice, its impact on healthcare resources needs to be better understood. We sought to determine the clinical impact of CTA on ICA referrals, CTA accuracy, and normalcy rate. ...
