Percutaneous treatment of coronary bifurcations is a complex issue due to numerous possible techniques and high risk of complications. Because of increasing interest in non-invasive imaging in interventional cardiology and growing quality of obtained images, we designed a prospective, randomized, single-blinded trial to evaluate the role of coronary computed tomography angiography (CCTA) in the...
OBJECTIVES This study sought to determine the accuracy of plaque pattern assessment by coronary computed tomography angiography (CCTA) to differentiate between early and advanced atherosclerotic lesions as defined by histology. BACKGROUND A ringlike attenuation pattern of coronary atherosclerotic plaques termed as napkin-ring sign (NRS) was described in CCTA of patients who had acute coronary...
BACKGROUND Coronary computed tomographic angiography (CCTA) facilitates comprehensive evaluation of coronary artery disease (CAD), including plaque characterization, and can provide additive diagnostic value to single-photon emission computed tomography (SPECT). However, data regarding the incremental prognostic value of CCTA to SPECT remain sparse. We evaluated the independent and incremental ...
BACKGROUND Assessment of chest pain patients remains a clinical challenge in the emergency department (ED). Several randomized controlled trials (RCTs) have shown the additive value of coronary computed tomographic angiography (CCTA) compared with standard care. Not all of them, however, had enough power to detect differences in clinical outcomes like revascularization. Therefore, we performed ...
OBJECTIVE Data describing the prevalence, characteristics and management of coronary chronic total occlusions (CTOs) in patients undergoing coronary CT angiography (CCTA) have not been reported. The purpose of this study was to determine the prevalence, characteristics and treatment strategies of CTO identified by CCTA. METHODS We identified 23 745 patients who underwent CCTA for suspected co...
Noninvasive visualization of the coronary arteries is the holy grail of cardiac imaging. Cardiac catheterization, the historic gold standard for coronary imaging, is invasive, costly, and often performed unnecessarily. Cardiac computed tomographic angiography (CCTA) is a widely available, cost-effective imaging modality that effectively images the coronary arteries. The most appropriate patient...
Coronary CT angiography (CCTA) has become an important noninvasive imaging modality in the diagnosis of coronary artery disease (CAD). CCTA enables accurate evaluation of coronary artery stenosis. However, CCTA provides limited information on the physiological significance of stenotic lesions. A noninvasive "one-stop-shop" diagnostic test that can provide both anatomical significance and functi...
Coronary computed tomographic angiography (CCTA) is emerging as a powerful non-invasive tool in the diagnosis of coronary artery disease (CAD). However, there is concern that CCTA is being used indiscriminately without sufficient examination of its added value vis-à-vis more established forms of non-invasive testing. With an evergrowing armament of non-invasive tests for the diagnosis and evalu...
The majority of acute coronary syndromes occur without warning due to rupture of coronary atherosclerotic plaques. Coronary lesions prone to rupture reveal several high-risk features that can be identified before the development of devastating clinical events, using modern imaging modalities. Recent advances in coronary computed tomography angiography (CCTA) allow the identification, quantifica...
Cardiac computed tomography angiography (CCTA) has technically matured into a robust imaging modality for various cardiac disorders. Whereas early trials focused on assessment of the efficacy of CCTA in comparison with established recommended methods, current research efforts focus on the effectiveness of the technique in specific clinical scenarios. In this article, we provide an overview of r...
