Coronary artery anomalies are rare, and their incidence varies from 0.6% to 1.3%. Conventional angiography is a commonly used modality for the assessment of coronary artery anomalies, but it may not identify and define the anatomy of anomalous arteries due to the complexity of the course and three-dimensional orientation of the arteries. We present a rare case of duplicated right coronary arter...

X-ray coronary angiography can provide rich dynamic information of cardiac and vascular function. Extracting contrast-filled vessel from the complex dynamic background (caused by the movement of diaphragm, lung, bones, etc.) in X-ray coronary angiograms has great clinical significance in assisting myocardial perfusion evaluation, reconstructing vessel structures for diagnosis and treatment of h...

PURPOSE Many patients admitted for acute myocardial infarction (AMI) have chronic renal insufficiency and erectile dysfunction (ED). This study aimed to evaluate the relationship between ED and the glomerular filtration rate (GFR) in patients with coronary artery disease. MATERIALS AND METHODS We studied 183 patients undergoing coronary angiography owing to AMI. The GFR was calculated and the...

OBJECTIVE To examine the role of transoesophageal echocardiography in the assessment of patients with coronary artery anomalies. BACKGROUND Coronary artery anomalies are difficult to detect clinically. Most are benign but some may produce symptoms that can be life threatening. Until recently the non-invasive assessment of coronary artery anomalies has been limited. METHODS The data base of ...

  Introduction: Percutaneous transluminal coronary angioplasty (PTCA) is an effective method for revascularizing of stenotic coronary vessels. Lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. Introduction of a noninvasive metho...

Coronary artery anomalies are usually incidentally diagnosed at the time of coronary angiography or autopsy. In a large series of 70,850 patients undergoing coronary angiography, the incidence of coronary anomalies was found to be 0.24-1.3%. The majority of these were reported to be anomalies of origin or distribution, with separate ostia of the left anterior descending artery and left circumfl...

Advances in 64-row multidetector computed tomography have provided noninvasive imaging of coronary arteries. The aim of this study was to evaluate the prevalence of coronary artery anomalies in Iranian symptomatic patients and to determine the presence of anomalies resulting in myocardial ischaemia without atherosclerotic plaque. This study was carried out in Tabriz University of medical scienc...

Background: This study assessed the application value of 64-slice spiral computed tomography angiography (CTA) in a follow-up evaluation of patients receiving coronary stent implantation. Materials and Methods: A total of 468 patients who underwent percutaneous coronary intervention (PCI) at our hospital between January 2013 and October 2016 were selected for this study. Coronary angiography an...

BACKGROUND There is a high incidence of anomalous coronary arteries in subjects with congenital heart disease. These abnormalities can be responsible for myocardial ischemia and sudden death or be damaged during surgical intervention. It can be difficult to define the proximal course of anomalous coronary arteries with the use of conventional x-ray coronary angiography. Magnetic resonance coron...
