conclusions our results show a significant association of nos3 and mthfr gene polymorphisms with coronary atherosclerotic lesions. therefore, these variants might influence the risk of coronary artery disease, specifically in the iranian population. results we specifically detected the nos3 tt genotype in 12 patients (11.11%) and did not find the same genotype in any of the controls. the freque...
Coronary CT angiography is widely recognised as a reliable imaging modality for the diagnosis of coronary artery disease. Coronary CT angiography not only provides excellent visualisation of anatomical changes in the coronary artery with high diagnostic value in the detection of lumen stenosis or occlusion, but also offers quantitative characterisation of coronary plaque components. Furthermore...
background: the optimal strategy in percutaneous coronary intervention (pci) for coronary artery bifurcation lesions has yet to be agreed upon. we compared a strategy for stenting the main vessel to provide a complete perfusion flow in the side branch, namely thrombolysis in myocardial infarction (timi) - iii, with a strategy for intervention in both the main vessel and the side branch (mv + sb...
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. imag...
Percutaneous coronary intervention in the setting of coronary bifurcation lesions is associated with increased risk for complications. The goal of this manuscript is to review the currently available classifications for coronary artery bifurcation lesions with a guide to the use of specific coronary bifurcation techniques based on lesion characteristics. Iran J Med Sci 2008; 33(4): 187-194.
aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...
introduction: heart failure is a major hazard for public health. despite recent advance in medical therapy, there is not enough information on the outcome of off-pump coronary artery bypass (opcab) and medical therapy on the patients with severe ventricular dysfunction and triple-vessel (cad). this study aimed to compare treatment outcomes and mortality rate in patients undergoing off-pump coro...
Background: To define and evaluate coronary contrast opacification gradients using prospectively ECG-gated single heart beat 320-detector row coronary angiography (CTA). Methods and Results: Thirty-six patients with normal coronary arteries determined by 320 x 0.5 mm detector row coronary CTA were retrospectively evaluated with customized image postprocessing software to measure Hounsfield Unit...
large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...
