We explored techniques that would allow the surgeon to localize coronary artery lesions demonstrated angiographically or to supplement angiographic information in patients who are undergoing coronary artery bypass procedures by intraoperative scanning of the coronary arteries using ultrasound. A 9-MHz electronically focused water-path ultrasound scanner was first used to image the coronary arte...

BACKGROUND Kawasaki disease is an inflammatory condition. Neutrophil to lymphocyte ratio is a marker reflecting inflammation. AIMS The aim of the study is to evaluate usefulness of neutrophil to lymphocyte ratio in diagnosis of Kawasaki disease and in prediction of coronary artery lesions. STUDY DESIGN Retrospective cross-sectional study. METHODS Seventy-five children with Kawasaki diseas...

A review is presented of what we know and what we suspect regarding the formation of coronary arteriosclerotic lesions in salmonids. Coronary lesions are a fact of life for both Atlantic and Pacific species of migrating salmon. Severe forms of lesions, usually restricted to the main coronary artery, are typically found in the majority of a salmon population when they are spawning. Vascular inju...

INTRODUCTION AND OBJECTIVES Non-invasive coronary artery angiography by 16 multidetector-row spiral computed tomography is a novel diagnostic tool whose reliability is still unclear. The aim of our study was to compare this technique with invasive coronary angiography. PATIENTS AND METHOD A total of 31 selected patients were examined with both angiographic methods. Non-invasive studies were p...

OBJECTIVES The aim of our study was to evaluate the feasibility of detecting coronary artery lesions using a new computed tomography (CT) scanner with 16 detectors and faster gantry rotation. BACKGROUND Computed tomography angiography of the coronaries permits assessment of the coronaries; however, image quality is still impaired by motion artifacts and calcifications. METHODS Sixty patient...

OBJECTIVE Because of beam-hardening and blooming artifacts, it is difficult to determine the degree of stenosis caused by calcified coronary artery plaques at coronary CT angiography (CTA). Our goal was to determine how accurate coronary CTA is in evaluating these lesions. MATERIALS AND METHODS Thirty-one patients who had one or more calcified coronary artery plaques at coronary CTA underwent...

Obstructive sleep apnea (OSA), a risk factor for coronary artery disease, remains under diagnosed. We investigated if OSA identified by the Berlin Questionnaire (BQ) is associated with the risk of coronary artery disease. Cases were patients referred for elective coronariography. The cases were classified with significant coronary lesions (stenosis ≥ 50% in an epicardial coronary) or without si...

BACKGROUND Intravascular ultrasound (IVUS) has become a valuable tool adjunctive to coronary angiography due to its ability to directly image atheroma and the vessel wall. We aimed to evaluate the use of IVUS during diagnostic angiography and coronary interventions in a coronary intervention academic high volume center of northern Greece. PATIENTS AND METHODS IVUS studies have been retrospect...
