BACKGROUND Measuring coronary artery calcium score (CACS) using a dual-source CT scanner is recognized as a major indicator for assessing coronary artery disease. The present study aimed to validate the clinical significance of CACS in predicting coronary artery stenosis and its severity. MATERIAL/METHODS This prospective study was conducted on 202 consecutive patients who underwent both conv...

The surgical management of tetralogy of Fallot (TF) may be complicated by anomalies in the course and distribution of coronary arteries. Selective coronary angiography was performed in 119 cases of TF in order to prevent injury of aberrant vessels. In 11 patients, anomalies in the origin of coronary branches were revealed (five patients with a single coronary ostium, five with the anterior desc...

Background: It has been implicated that obstructive sleep apnea (OSA) is associated with increased risk of cardiovascular disease including stroke, myocardial infarction, coronary artery disease (CAD) and hypertension. The aim of this study was to investigate the correlation between OSA and severity of atherosclerosis assessed by angiography. Methods: This study included 337 patients ...

spontaneous coronary artery dissection (scad) is a rare condition that can result in unstable angina, acute myocardial infarction, and sudden death. this condition may occur particularly in women during late pregnancy and in the postpartum period. we present the case of a 33-year-old african american woman, who had spontaneous left anterior descending coronary artery (lad) dissection two weeks ...

cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...

background: investigators frequently encounter continuous outcomes with plenty of values clumped at zero called semi-continuous outcomes. the gensini score, one of the most widely used scoring systems for expressing coronary angiographic results, is of this type. the aim of this study was to apply two statistical approaches based on the categorization and original scale of the gensini score to ...

Purpose: To assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in Cardiac Magnetic Resonance of patients with history of remote myocardial infarction. Materials and Methods: The Cardiac Magnetic Resonance images of sixty patients with history of remote ST segment or non-ST segment elevation myocardial infarction were ...

We estimated the frequency of anatomic variations in origin of the left coronary artery in a Turkish population by analyzing the angiographic data of 10,042 consecutive adult patients undergoing coronary angiography. Among 10,042 adult patients, 5 (0.04%) patients (4 men and 1 woman, age range 40-74, median 58 years old) had anomalous origin of the left main coronary artery. The left main coron...

BACKGROUND Accelerated coronary atherosclerosis is a major factor limiting allograft longevity in cardiac transplant recipients. Histopathology studies have demonstrated the insensitivity of coronary angiography for detecting early atheromatous disease in this patient population. Intracoronary ultrasound is a new imaging technique that provides characterization of vessel wall morphology. The pu...
