INTRODUCTION Evidence for the current guidelines for the treatment of patients with chronic total occlusions (CTO) in coronary arteries is limited. In this study we identified all CTO patients registered in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and studied the prevalence, patient characteristics and treatment decisions for CTO in Sweden. METHODS AND RESULTS Between...
BACKGROUND AND OBJECTIVES It has been demonstrated that the anomalous origin of coronary arteries (AOCA) are generally asymptomatic and rare diseases. However, some cases can cause severe life threatening events. To detect these anomalies, coronary angiographies and autopsies were used to detect coronary artery anomalies, but these procedures have limitations because of their invasiveness. The ...
Coronary Computed Tomography Angiography in the Assessment of Acute Chest Pain in the Emergency Room
The coronary computed tomography angiography has recently emerged as an accurate diagnostic tool in the evaluation of coronary artery disease, providing diagnostic and prognostic data that correlate directly with the data provided by invasive coronary angiography. The association of recent technological developments has allowed improved temporal resolution and better spatial coverage of the car...
BACKGROUND AND OBJECTIVE The coronary slow flow phenomenon (CSFP) is a coronary artery disease with a benign course, but its pathological mechanisms are not yet fully understood.The purpose of this controlled study was to investigate the cellular content of blood in patients diagnosed with CSFP and the relationship of this with coronary flow rates. METHODS Selective coronary angiographies of ...
In the era of Multislice Computed Tomography (MSCT), few studies have been dedicated to the evaluation of coronary anomalies and variants. We aim to present, describe and assess the prevalence of congenital coronary variants and anomalies (CVA) in the MSCT coronary angiographic studies performed in our department. All the MSCT coronary angiographies performed in our department, between April 1,...
A 50-year-old male smoker was admitted to our hospital for chest pain at rest. Echocardiography showed apico-lateral hypokinesis and normal global left ventricular ejection fraction. Coronary angiography was performed and an unexpected double coronary anomaly (CA) was found. The right coronary (RCA), left circumflex (Cx) and left anterior descending (LAD) arteries originated from the right aort...
BACKGROUND The clinical conditions of various diseases, including coronary artery disease, are determined by genetics and the environment. Previous investigations noted the significance of genetic mutations and polymorphisms in cases of coronary spasm. CASE REPORT We report on monozygotic identical twins who almost simultaneously presented with vasospastic angina. The 58-year-old younger twin...
Background: Streptokinase, which is injected intravenously with a standard dose of 1.5 MIU, is the most widely used thrombolytic agent around the world. What is so important about this bioproduct is the level of antistreptokinase (anti-sk) antibody in the population, which is directly correlated to the incidence of streptococcal infections in that population. Objective: Since Iran is an endemic...
A myocardial bridge (MB) is a common anatomic variant, most frequently located in the left anterior descending coronary artery, where a portion of the coronary artery is covered by myocardium. Importantly, MBs are known to result in a proximal atherosclerotic lesion. It has recently been postulated that these lesions predispose patients to acute coronary events, even in cases of otherwise low-r...
