Angiology, 1980
Coronary ostial stenosis as a complication of atherosclerosis is a rarely emphasized angiographic finding. Its recognition is important because of the adverse prognosis of left main stenosis and the inherent risks during catheterization of these patients. Recently 3 patients were identified with left coronary ostial stenosis.

Postperfusion Coronary Stenosis
The Annals of Thoracic Surgery, 1987A patient is described who had left main coronary artery stenosis four months after aortic valve replacement. He was seen with unstable angina, and subsequent catheterization revealed stenosis of a previously normal left main coronary artery. The diagnosis, treatment, and means of prevention are discussed.

Nonsyphilitic Coronary Ostial Stenosis
Archives of Surgery, 1977From October 1970 to June 1977, a total of 15 patients (12 women) were seen with atherosclerotic coronary ostial stenosis (14 left, one right). All patients had angina and two had aortic valve disease. Additional coronary arterial disease was present in nine. One patient declined surgery and died four months later after myocardial infarction.

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).

Congenital coronary sinus stenosis
Echocardiography, 2016Congenital coronary sinus (CS) stenosis is a rare malformation. We present five patients with congenital coronary sinus stenosis (CSS) and identified another nine cases reported in the literature between 1980 and 2016. Congenital CSS may be associated with an unroofed CS, a coronary artery–coronary sinus fistula, or other cardiac anomalies.

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]).

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.

Coronary Atherosclerosis in Mitral Stenosis
Chest, 1982Eighty-two patients with mitral stenosis underwent cardiac catheterization with coronary angiography. Twenty-one patients (26 percent) had coronary artery disease. Characteristics of the mitral valve area, cardiac output, pulmonary artery pressure, pulmonary vascular resistance, left ventricular end-diastolic pressure, left ventricular ejection ...

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.

Hemodynamics of coronary artery stenosis
Canadian Journal of Physiology and Pharmacology, 1984A model is proposed to study the hemodynamics of various types of coronary stenosis. The model coronary artery is assumed to be an elastic tapered tube. A progressive degree of concentric and eccentric stenoses are studied. Measured pulsatile coronary pressure, flow, and intramyocardial pressure are used as input data to calculate the pressure and ...
