Can Coronary Computed Tomography Angiography Replace Invasive Angiography? [PDF]

Circulation, 2015
One million patients undergo invasive coronary angiography (CA) in the United States every year.1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for

Coronary computed tomography angiography equals invasive angiography for the prediction of coronary revascularization [PDF]

Advances in Interventional Cardiology, 2019
Growing role of coronary computed tomography angiography (CTA) as a diagnostic tool in patients with suspected coronary artery disease (CAD) calls for better recognition of its value in clinical decision making as compared to the gold standard of invasive coronary angiography (ICA).To assess the diagnostic value of quantitative coronary computed ...

Determinants of Pericoronary Adipose Tissue Attenuation on Computed Tomography Angiography in Coronary Artery Disease

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Recent studies have reported the association between pericoronary inflammation assessed by pericoronary adipose tissue attenuation (PCATA) on computed tomography angiography and worse outcomes in patients with coronary artery disease.

Coronary computed tomography angiography in children [PDF]

Pediatric Radiology, 2021
Imaging the coronary arteries of children, with their faster heart rates, small vessel size and common inability to lie still or breath-hold, has been a major challenge. With numerous advances in technology, CT examinations can now be performed quickly, often with children free-breathing and with much lower radiation doses than previously. This has led

Early computed tomography coronary angiography in adults presenting with suspected acute coronary syndrome: the RAPID-CTCA RCT

Health Technology Assessment, 2022
Background: Acute coronary syndrome is a common medical emergency. The optimal strategy to investigate patients who are at intermediate risk of acute coronary syndrome has not been fully determined.

Coronary computed tomography angiography [PDF]

Canadian Medical Association Journal, 2015
Contrast medium is injected intravenously, and multidetector technology is used to take an image of the heart during a single breath hold (acquisition time ~8 s for 64 detectors). Blockade is recommended for patients with heart rates faster than 65 beats/min to improve image quality and to ...

Isolated Antineutrophil Cytoplasmic Antibody-Associated Coronary Vasculitis and Valvulitis

JACC: Case Reports, 2021
A 30-year-old woman presented with angina pectoris. Coronary angiography revealed severe stenosis in the left main and right coronary arteries that did not improve with intracoronary nitroglycerin.

Giant coronary aneurysm caused by Kawasaki disease: consistency between catheter angiography and electrocardiogram gated dual-source computed tomography angiography [PDF]

Korean Journal of Pediatrics, 2015
We present the case of a 5-year-old child with coronary complications due to Kawasaki disease; this patient unintentionally underwent both dual-source computed tomography (DSCT) coronary angiography and invasive coronary angiographic examination in 2 ...

Detection of coronary artery disease based on the calcification index obtained by helical computed tomography

Arquivos Brasileiros de Cardiologia, 2000
OBJECTIVE: To assess the relation between coronary artery disease and the calcification index on helical computed tomography. METHOD: We studied 22 patients (ages ranging from 40 to 70 years) who underwent coronary angiography because of chest pain ...

Coronary micro-computed tomography angiography in mice [PDF]

Scientific Reports, 2020
AbstractCoronary computed tomography angiography is an established technique in clinical practice and a valuable tool in the diagnosis of coronary artery disease in humans. Imaging of coronaries in preclinical research, i.e. in small animals, is very difficult due to the high demands on spatial and temporal resolution. Mice exhibit heart rates of up to
