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...

purpose: to assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in cardiac magnetic resonance of patients with history of remote myocardial infarction. materials and methods: the cardiac magnetic resonance images of sixty patients with history of remote st segment or non-st segment elevation myocardial infarction were revi...

A 59-year-old HIV positive female presented with cardiac symptomatology. Cardiology workup included a cardiac catheterization during which a carotid angiogram was performed demonstrating a 90% stenosis of the right carotid artery. The stenosis was the result of lymphoid hyperplasia with pseudo obstruction of the right carotid artery. Patients who have acquired human immunodeficiency virus (HIV)...

CONTEXT The annual risk of ischemic stroke in patients with asymptomatic carotid artery stenosis is about 2% during the short-term (2-3 years), but the long-term risks of stroke and other vascular events are unknown, although they may affect surgical decision making. OBJECTIVE To evaluate the long-term risk of stroke and other vascular events in patients with asymptomatic carotid artery steno...

BACKGROUND There are controversies regarding the usefulness of coronary artery calcium score (CACS) for predicting coronary artery stenosis. The aim of this study was to determine the prognostic value of CACS for determining the presence and severity of coronary artery disease (CAD) in patients with sign and symptoms of the disease. MATERIAL/METHODS In this cross-sectional study, 748 consecut...

BACKGROUND Significant left main coronary artery stenosis is an accepted indication for surgical revascularization. The potential of angiography to evaluate the hemodynamic severity of a stenosis is limited. The aims of the present study were to assess the long-term clinical outcome of patients with an angiographically equivocal left main coronary artery stenosis in whom the revascularization s...

BACKGROUND Increased prevalence of various vascular diseases is common in type 2 diabetes mellitus. However, the increased prevalence of renal artery atheroma resulting in renal artery stenosis in patients with diabetes mellitus has not been fully assessed. We used magnetic resonance angiography to assess the prevalence of renal artery stenosis in a group of patients with hypertension and type ...

We present a case in which angioplasty alone and stent-assisted angioplasty were performed in the same patient to treat medically refractory intracranial stenoses. This elderly patient with presumed intracranial atherosclerotic disease underwent angioplasty alone for his anterior cerebral artery stenosis. Stent-assisted angioplasty was used for treatment of his ipsilateral middle cerebral arter...

OBJECTIVE To study the efficacy, safety, and feasibility of stent-assistant angioplasty (SAA) in the treatment of symptomatic vertebrobasilar artery stenosis in the elderly. METHODS SAA was performed in 26 elderly patients with symptomatic vertebrobasilar artery stenosis. The success rate, perioperative complications, and long-term effectiveness were evaluated. RESULTS A total of 29 balloon...
