Coronary Ostial Stenosis

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, 1987
A 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.

Coronary Atherosclerosis in Mitral Stenosis

Chest, 1982
Eighty-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 ...

Nonsyphilitic Coronary Ostial Stenosis

Archives of Surgery, 1977
From 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.

Hemodynamics of coronary artery stenosis

Canadian Journal of Physiology and Pharmacology, 1984
A 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 ...
