Pathways and Functional Significance of the Coronary Collateral Circulation
TL;DR: Comparisons of coronary arteriograms and left ventriculograms of patients having significant coronary artery disease indicate that collateral circulation plays an important role in preserving myocardial contractility in patients with coronary arteries disease.
Journal ArticleDOI
Functional importance of the human coronary collateral circulation.
TL;DR: Myocardial ischemia was more prevalent in patients with than in those without collateral vessels as evidenced by a significantly greater frequency of abnormal post-exercise electrocardiograms and myocardial lactate production.
Journal ArticleDOI
Quantitative left ventricular wall motion analysis: a comparison of area, chord and radial methods.
TL;DR: The area method, of the techniques examined, was best for the quantitative analysis of LV wall motion abnormalities, because it had the lowest failure rate, best reflected symmetric uniform motion of the ventricular silhouette.
Journal ArticleDOI
Determinants and protective potential of coronary arterial collaterals as assessed by an angioplasty model
TL;DR: The data of both study phases suggest that left ventricular function and clinical outcome after abrupt coronary closure are determined by an interaction between location of the coronary artery obstruction and the amount of collateral flow.

Intraoperative Coronary Collateral Function in Patients With Coronary Occlusive Disease Nitroglycerin Responsiveness and Angiographic Correlations
Robert E. Goldstein,Edward B. Stinson,James L. Scherer,Ronald P. Seningen,Todd M. Grehl,Stephen E. Epstein +5 more
TL;DR: Comparison of baseline data with preoperative angiography revealed a correlation between the size and extent of coronary collaterals and physiologic evidence of collateral function and angiographic appearance of coronary Collaterals accurately predicts collateral function during bypass surgery.

Localized disorders in myocardial contraction. Asynergy and its role in congestive heart failure.
TL;DR: The pattern of left ventricular contraction is described as a "series of sequential fractionate contractions of muscle bundles" and the possibility that unco-ordinated contraction of the heart results from a combination of normal and abnormal muscle has received little attention.
Journal ArticleDOI
Diagnostic Accuracy of Selective Coronary Cinearteriography
TL;DR: The data support the conclusion that selective coronary cinearteriography is a highly accurate means of evaluating the morphology of both normal and diseased coronary vessels, but high quality arteriograms and experienced interpreters are required.
Journal ArticleDOI
Clinical correlation of coronary arteriography.
TL;DR: The severity of the atherosclerotic process in terms of its stenosing effect on the vascular vessels increased materially as the electrocardiographic tracing deteriorated from normal to a pattern indicative of a past transmural myocardial infarction.
Journal ArticleDOI
Relation of the degree of coronary-artery disease and of myocardial infarctions to cardiac hypertrophy and chronic congestive heart failure.
TL;DR: A large number of cases of heart failure in aging persons are usually assumed to be due to coronary arteriosclerosis (arteriosclerotic heart disease, ischemic heart disease) if other identifiable causes of ...
