Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

a double left anterior descending (lad) coronary artery emerging from the left and right coronary arteries is classified among rare coronary anomalies. we herein report a 73-year-old man presenting with acute coronary syndrome (posterolateral myocardial infarction). he was admitted with typical chest pain, and due to his progressive ischemic changes on electrocardiography (ecg) and elevated car...

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 ...

anomalous origin of the left coronary artery from the pulmonary artery (alcapa) is a rare congenital cardiac malformation. we report three cases of alcapa who survived to adulthood. the first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with alcapa using cardiac catheterization and coronary computed tomographic angiography (cta). the second case was a 30-...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

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 ...

anomalies of origin, course, and distribution of coronary arteries, including single coronary artery, are well known in patients with tetralogy of fallot. however, to the best of our knowledge, there is no published case report of pentalogy of fallot with a single coronary artery. herein, we introduce a 22-year-old female patient diagnosed via echocardiography and cardiac catheterization preope...
