Background & Aims: Significant left main coronary artery disease (LMCAD) is found in 3 to 6 percent of all patients who undergo coronary arteriography. LMCAD usually requires an emergent surgery that has a higher rate of mortality and complications. The risk factors of left main involvement in previous studies are controversial. The aim of this study was to determine the traditional risk factor...

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...

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...

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...

background : st-elevation myocardial infarction (stemi) is a major cause of cardiovascular mortality worldwide. there are differences between very young patients with stemi and their older counterparts.   this study investigates the demographics and clinical findings in very young patients with stemi. methods: through a review of the angiography registry, 108 patients aged ≤ 35 years (group i) ...
