Vessel foreshortening is a major limitation of standard coronary angiography due to the 2-dimensional representation of 3-dimensional structures. Three-dimensional models may overcome it. The aim of this study was to compare measurements of coronary segments from quantitative coronary angiography (QCA) in an operator-selected "working view" of standard 2-dimensional coronary angiography with th...

OBJECTIVE To determine coronary artery anomalies in tetralogy of Fallot in Pakistani children as seen on angiography. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY The National Institute of Cardiovascular Diseases, Karachi, Pakistan from July 2006 to July 2007. METHODOLOGY Children under 15 years of age with echocardiographic diagnosis of tetralogy of Fallot were included in the s...

Myocardial ischaemia may result from congenital abnormalities in the origin or distribution of the coronary arteries. Coronary obstruction may also develop at a young age in some rare hereditary disorders such as Hurler's syndrome, homocystinuria or pseudoxanthoma elasticum. The coronary arteries may be the site of embolism; ostial stenosis may complicate luetic (or other) aortitis or coronary ...

PURPOSE To perform a systematic review of the diagnostic value of 64-multislice CT (MSCT) angiography in the detection of coronary artery disease (CAD) when compared to conventional coronary angiography. MATERIALS AND METHODS A search of PUBMED and MEDLINE databases for English literature was performed. Only studies with at least 10 patients comparing 64-slice MSCT angiography with convention...

BACKGROUND Congenital anomalies of the coronary arteries (CAs) are rare and are often diagnosed incidentally during a conventional coronary angiography. Recently, the incidence of these congenital defects is on the rise particularly after the introduction of the electrocardiography (ECG) gated coronary computed tomographic angiography (CCTA). This innovative radiological screening modality has ...

BACKGROUND Several studies have shown that increased carotid intima-media thickness (CIMT) confers risk of future coronary artery disease (CAD) and stroke. The present study aimed at investigating whether CIMT is a predictor of CAD in South African black patients. METHODS AND RESULTS This was a prospective study of 53 patients, 41 men and 12 women, with ages ranging from 30 to 70 years. All p...

introduction: during the angiography of coronary vessels a great amount of  iodine mixed with radio-contrasts enter the body, and if autonomic centers exist in thyroid it causes hyperthyroidism. this can be dangerous in patients with cronary artery disease (cad). this study aimed to determine the effect of a radio-contrast used in coronary angiohraphy on thyroid’s function in patients referring...

Coronary artery aneurysms are rare anomalies that are usually incidental findings in coronary angiography. We present the case of a 64-year-old male patient with a recent episode of epigastric pain, nausea and vomiting, accompanied by electrocardiographic alterations and positive troponin I. As the symptoms persisted, the patient was referred for coronary angiography, during which a significant...
