UNLABELLED Coronary artery anomalies are rare in population and most of them are found incidentally during coronary angiography. Percutaneous treatment of critical lesions on anomalous arteries may lead to difficulties due to their abnormal origin or course. Herein, we report a 65-year-old male patient presented with recent onset chest pain. Electrocardiogram and transthoracic echocardiography ...

coronary artery anomalies are rare, with their incidence varying from 1 to 5%. angiography is a commonly used modality for the assessment of coronary artery anomalies. based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. coronary artery anomalies may cause myocardi...

INTRODUCTION The severity of coronary artery stenosis which leads to myocardial infarction (MI) has been a matter of controversy. Historical data are in favor of mild luminal stenosis (<50% diameter stenosis) while recent studies suggest hemodynamically-significant coronary stenosis as the main substrate for subsequent MI. Also, mechanical stress resulted from coronary artery movement (CAM) may...

OBJECTIVE To assess the prognostic value of low-dose 64-slice coronary CT angiography (CCTA) using prospective ECG triggering in a patient population with known or suspected coronary artery disease (CAD). DESIGN Longitudinal follow-up study. SETTING Tertiary referral cardiac imaging centre. PATIENTS 434 consecutive patients who were referred for evaluation of CAD by CCTA. METHODS The pr...

Improvements in multislice computed tomography (MSCT) angiography of the coronary vessels have enabled the minimally invasive detection of coronary artery stenoses, while quantitative coronary angiography (QCA) is the accepted reference standard for evaluation thereof. Sixteen-slice MSCT showed promising diagnostic accuracy in detecting coronary artery stenoses haemodynamically and the subseque...

Kawasaki disease is a multisystemic vasculitis that can result in coronary artery lesions. It predominantly affects young children and is characterized by prolonged fever, diffuse mucosal inflammation, indurative oedema of the hands and feet, a polymorphous skin rash and non-suppurative lymphadenopathy. Coronary artery involvement is the most important complication of Kawasaki disease and may c...

Coronary CT angiography (CCTA) has become an important noninvasive imaging modality in the diagnosis of coronary artery disease (CAD). CCTA enables accurate evaluation of coronary artery stenosis. However, CCTA provides limited information on the physiological significance of stenotic lesions. A noninvasive "one-stop-shop" diagnostic test that can provide both anatomical significance and functi...

I read with interest the article by Kawamura et al. entitled ‘Patency rate of the internal thoracic artery to the left anterior descending artery bypass is reduced by competitive flow from the concomitant saphenous vein graft in the left coronary artery’ [1]. The authors proved that long-term patency of the internal thoracic artery (ITA) left anterior descending (LAD) coronary bypass was affect...

This review explores evidence for the reversibility of atherosclerosis and augmentation of angiography with noninvasive arterial wall imaging. Meta-analysis from coronary angiographic trials demonstrates that regression and stabilization are 1.5 to 2 times more common in treated than placebo subjects, and progression is reduced by half in treated subjects. Odds ratios for clinical coronary even...
