OBJECTIVE To compare the coronary anatomy and the location of coronary lesions in monozygotic and dizygotic twin pairs affected with coronary artery disease. DESIGN Coronary angiographic findings were compared with respect to the distribution of coronary blood supply and the location of coronary lesions. MAIN OUTCOME MEASURES Distribution of coronary blood supply, diameters and length of pr...
The relationships among clinical variables, coronary anatomy, and left ventricular function during the early hours of acute myocardial infarction (AMI) were evaluated from data acquired in the Western Washington Intracoronary Streptokinase Trial. All patients had symptoms and electrocardiographic changes typical of AMI. All data were obtained before treatment with streptokinase. Mean time to ca...
BACKGROUND Appropriate clinical decisions concerning diagnosis and treatment of coronary artery disease rely on correct integration of data on coronary anatomy and myocardial perfusion. The purpose of this article is to introduce a new left ventricular segmentation model for improved alignment of coronary arterial segments and myocardial perfusion territories, designed for the CORE320 study. ...
The transradial approach is safe and effective for coronary procedures. However, its use may be compromised in cases of variations in radial artery anatomy, spasms, and negative Allen's test. The transulnar approach emerges as a viable alternative to transradial approach. We report on a patient who underwent primary angioplasty via ulnar artery without ischemic hand complications despite prior ...
Introduction: Aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. Recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. The purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients ho...
Our case report describes a very rare example of isolated right ventricular infarction in a 39-year-old patient with nondominant anomalous right coronary artery. We took advantage of both computed tomography and magnetic resonance imaging techniques to diagnose this case. The computed tomography scan characterized the anatomy and course of the right coronary artery and cardiac magnetic resonanc...
Anomalous origin of Left Coronary Artery from Pulmonary Artery (ALCAPA) is a rare congenital anomaly. Its survival into adulthood is further rare. Clinical manifestations result from evolving morphological - functional alterations in pulmonary circulation that occur after the birth. We report a case of 43 year old adult patient with effort angina and without any ECG or Echo abnormalities. On co...
