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...

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...

conclusions coronary artery aneurysm should be a differential diagnosis in cases of mediastinal cyst and mass lesion. case presentation a 32-year-old woman presented with edema of the upper and lower limbs, palpitation, and chest pain, and was diagnosed with a giant right coronary artery aneurysm that had initially mimicked a mediastinal cyst. although computed tomography (ct) suggested a media...

spontaneous coronary artery dissection (scad) is a rare and important cause of acute coronary syndrome and sudden cardiac death. various etiologies are thought to be responsible for this condition, among which underlying atherosclerosis seems to be the most common. scad is predominant in women and is usually diagnosed via coronary artery angiography. therapeutic interventions include medical th...

traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...
