OBJECTIVE This study aimed to assess the incidence of coronary anomalies using 64-multi-slice coronary computed tomography (MSCT). METHODS The diagnostic MSCT scans of 745 consecutive patients were reviewed. RESULTS The incidence of coronary anomalies was 4.96%. The detected coronary anomalies included the conus artery originating separately from the right coronary sinus (RCS) (n = 8, 1.07%...

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 ...

  Objective(s): Apolipoprotein E genotype (APOE) polymorphism affects lipid levels and coronary artery disease (CAD) risk. The aim of this study was to study the association of the Apolipoprotein E genotypes with coronary artery disease in the Iranian population.   Materials and Methods: The Apolipoprotein E genotype in DNA samples extracted from 66 CAD+ patients and 61 control s...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

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...

BACKGROUND AND OBJECTIVES Coronary artery anomalies are found in approximately 1% of patients undergoing diagnostic coronary angiography (CAG). Angiographic recognition of these vessels is important because of their clinical significance and importance in patients undergoing coronary angioplasty or cardiac surgery. There are fairly enough reports concerning the incidence of coronary anomalies i...

Congenital anomalies in the origin, course or distribution of the epicardial coronary arteries are found in 1 to 2 percent of the population. Asymptomatic coronary artery anomalies are generally diagnosed incidentally by routine coronary angiography or during autopsy. Approximately 80% of congenital anomalies of the coronary arteries are benign, while 20% of coronary artery anomalies produce li...

BACKGROUND Coronary artery anomalies are not common, but could be very serious. OBJECTIVES This study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (MDCT). PATIENTS AND METHODS The results of cardiac MDCT study in 2697 consecutive patients were analyzed retrospectively. Acquisition was performed by a 64-detector row CT machine. ...

Recent technical advances in computed tomography (CT) have improved image quality, diagnostic performance and accuracy of coronary CT angiography (CCTA). Latest dose-reduction strategies reduce radiation dose to an acceptable level even lower than that from conventional coronary angiography. CCTA is a noninvasive imaging modality which can effectively show complex coronary artery anatomy, varia...
