Isolated coronary ostial stenosis
Catheterization and Cardiovascular Diagnosis, 1986AbstractWe have examined 5 patients with typical angina pectoris and found them to have left coronary ostial stenosis without evidence of any other coronary arterial disease and without evidence of aortic disease (Takayasu aortitis, syphilitic aortitis, or familial hypercholesterolaemia).

Left coronary ostial stenosis: Comparison with left main coronary artery stenosis
The Annals of Thoracic Surgery, 1989We compared 147 consecutive patients who had left coronary ostial stenosis with 254 consecutive patients who had left main coronary artery stenosis treated with coronary artery bypass grafting. Mean age for the left main group was 61.6 years versus 59.7 years for the left ostial group (p = not significant [NS]).

Coronary artery stenosis in an australian population
Pathology, 1993The purpose of this study was to examine the extent and severity of coronary stenosis in an Australian population. The subjects were autopsy cases among people aged 20-69 yrs dying in and out of hospital in the Newcastle area of New South Wales in 1985-86.

Iatrogenic coronary artery stenosis following coronary stenting
Catheterization and Cardiovascular Interventions, 1999We present 6-month follow-up of 435 patients undergoing stent deployment. Forty-four patients were referred because of myocardial ischemia related to the stented artery. In six of these patients (14%), the stented vessel revealed a new proximal lesion separated from the stented portion, which warranted further intervention.

Adrenergic Coronary Vasoconstriction with Coronary Stenosis
1982Clinical studies suggest that alpha-receptor-mediated (alpha-mediated) coronary vasoconstriction may play a role in the genesis of myocardial ischemia in patients with coronary artery stenoses. Mudge et al. [11, 12] have demonstrated an inappropriate increase in coronary vascular resistance in response to the cold pressor test in patients with coronary

Cardiovascular Imaging: Coronary Artery Stenosis
Hospital Practice, 1984The ability to accurately measure the effects of a stenosis by perfusion imaging with PET has significant implications for clinical use. This noninvasive technique may facilitate early diagnosis in asymptomatic patients and allow assessment of disease progression. In the meantime, quantitative angiography can be useful.

Coronary Ostial Stenosis in Takayasu's Arteritis
Chest, 1980A patient with Takayasu's arteritis with left coronary ostial narrowing is presented. The dramatic clinical and pathologic findings are discussed in detail. Emphasis is placed on making the diagnosis as soon as possible, in order to expedite bypass surgery to prolong life.

Flow Dynamics in Coronary Stenosis
1990The pressure loss across coronary artery stenosis is mainly caused by two factors: viscous friction loss by stenotic segments and separation loss by the flow separation after (and before) stenosis. When the percentage diameter stenosis increases, the coronary flow reserve decreases. In addition to percentage stenosis, the length of the stenosis and the

Visualization of Coronary Artery Stenosis
Imaging Decisions MRI, 2008SummaryImage quality of a computed tomography image is dependent on temporal and spatial resolution. In this article both factors are addressed in relation to image quality. The effect of temporal resolution on image quality is assessed by comparing image quality scores of dual‐source computed tomography (DSCT) to single‐source 64‐slice multi‐detector ...
