Coronary artery anomalies (CAAs) are present at birth, but are usually asymptomatic and are found during coronary angiography or multi-slice computed tomography (MSCT) detection. The most common coronary anomaly is the separating origin of left anterior descending coronary artery (LAD) and left circumflex artery (LCX) from the left sinus of Valsalva, and this variant is benign. Herein, we prese...

OBJECTIVE To retrospectively determine the imaging features of coronary artery anomalies depicted at dual-source computed tomographic coronary angiography (DSCT-CA). METHODS We reviewed the case histories of 12,145 patients with suspected coronary arterial disease who underwent DSCT-CA at our institution. Multiplanar reformation, maximum-intensity projection, and volume-rendered imaging were ...

Objectives To develop prediction models that better estimate the pretest probability of coronary artery disease in low prevalence populations. Design Retrospective pooled analysis of individual patient data. Setting 18 hospitals in Europe and the United States. ParticipantsPatients with stable chest pain without evidence for previous coronary artery disease, if they were referred for computed t...

Objective Coronary artery anomaly (CAA) is a remarkable etiological factor for sudden cardiac death in young adults. The incidence of CAA is unknown, with most reliable data available based on postmortem/angiography investigations. This study aimed to assess the prevalence of different forms of coronary anomalies, and to investigate the relationships between demographic data and occurrence of C...

background and objectives: the association between metabolic syndrome (mets) and hyperuricemia has been formerly studied mostly in healthy people in western countries. we tried to examine the relationship betweenhyperuricemia and mets in an iranian population undergoing coronary angiography. materials and methods: from march 2008 to september 2008, we studied 465 patients (260 men, 55.9%) unde...

BACKGROUND Coronary collateral flow is an alternative source of myocardial perfusion in patients with totally occluded coronary arteries. Clinical evaluation of collateral flow has been limited by the need of invasive measurements. We investigated whether noninvasive coronary computed tomographic angiography can evaluate the angiographic extent of coronary collateral flow. METHODS AND RESULTS...

BACKGROUND Coronary artery anomalies (CAAs) are currently undergoing profound changes in understanding potentially pathophysiological mechanisms of disease. Aim of this study was to investigate the prevalence of anomalous origin and course of coronary arteries in consecutive symptomatic patients, who underwent cardiac 64-slice multidetector-row computed tomography angiography (MDCTA). METHODS...

Coronary artery anomalies include anomalies of origin, termination, structure or course. Coronary artery fistulae (CAF) are classified as abnormalities of termination and are considered a major congenital anomaly. A coronary artery fistula involves a sizable communication between a coronary artery, bypassing the myocardial capillary bed and entering either a chamber of the heart (coronary-camer...

Background and Objective: Coronary artery disease (CAD) is one of the most common diseases today. Among the diagnostic methods, angiography is the main and gold standard in the diagnosis Since angiography is an invasive procedure, this procedure complications range widely from minor problems with short term sequelae to life threatening ones may cause irreversible damage or even death. Materials...
