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...

a 48-year-old woman was admitted to the emergency department with complaints of typical chest pain, cold sweat, and dyspnea of 24 hours’ duration. she had a history of hypertension, hyperlipidemia, and diabetes mellitus for many years. on admission, her electrocardiogram (ecg) revealed normal sinus rhythm and dynamic t inversion in the precordial leads. her enzyme levels were normal. transthora...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

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...

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...

x-ray coronary angiography has been a gold standard in the clinical diagnosis and interventional treatment of coronary arterialdiseases for decades. in angiography, a sequence of images is obtained, a few of which are suitable for physician inspection. thispaper proposes an automatic algorithm for the extraction of one or more frames from an angiogram sequence, which is most suitablefor diagnos...

spontaneous coronary artery dissection (scad) is a rare condition that can result in unstable angina, acute myocardial infarction, and sudden death. this condition may occur particularly in women during late pregnancy and in the postpartum period. we present the case of a 33-year-old african american woman, who had spontaneous left anterior descending coronary artery (lad) dissection two weeks ...

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 ...

transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. radial artery pseudoaneurysms present as a rare complication of transradial catheterization. although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the tr band ® (terumo medical corporation, somerset, nj) is a ...
