The prevalence of coronary artery anomalies with coronary computed tomography.

Background/aim: In this study, the aim is to investigate the prevalence of various coronary artery anomalies (CAAs), evaluated by 256-detector row coronary computed tomography (CCT), within the Turkish population.

Materials And Methods: We included 2973 patients who had received CCT. The high take-off right coronary artery (RCA) and left coronary artery (LCA), the RCA arising from the left sinus (LS), the LCA arising from the right sinus (RS), the circumflex artery (CX) arising from the RS, the single coronary ostium originating from the RS, the CX arising from the RCA, and the RCA arising from the pulmonary artery were evaluated.

The Risk of Atrial Fibrillation With Ivabradine Treatment: A Meta-analysis With Trial Sequential Analysis of More Than 40000 Patients.

Recent trials reported that risk of atrial fibrillation (AF) is increased in patients using ivabradine compared with controls. We performed this meta-analysis to investigate the risk of AF association with ivabradine treatment on the basis of data obtained from randomized controlled trials (RCTs). We searched PubMed, EMBASE, Scopus, and the Cochrane Library for RCTs that comprised >100 patients.

Efficacy of coronary fractional flow reserve using contrast medium compared to adenosine.

Introduction: Coronary fractional flow reserve (FFR) is recommended as the gold standard method in evaluating intermediate coronary stenoses. However, there are significant debates concerning the agents and the timing of the measurement.

Aim: To compare the contrast medium induced Pd/Pa ratio (CMR) with the FFR.

Coronary Artery Disease Risk Factors, Coronary Artery Calcification and Coronary Bypass Surgery.

Introduction: Atherosclerosis is an intimal disease which affects large and medium size arteries including aorta and carotid, coronary, cerebral and radial arteries. Calcium accumulated in the coronary arterial plaques have substantial contribution to the plaque volume. The aim of our study is to investigate the relationship between coronary artery disease (CAD) risk factors and coronary arterial calcification, and to delineate the importance of CACS in coronary artery bypass surgery.

The evaluation of the clinical utility of urocortin 1 and adrenomedullin versus proBNP in systolic heart failure.

Objective: Urocortin 1 (UCN1) has vasodilator, diuretic, and natriuretic effects, and its expression increases in heart failure (HF). Adrenomedullin (ADM) increases cardiac output and lowers blood pressure in healthy men and in patients with heart failure. The aim of the study was to determine UCN1 and ADM levels in patients with HF, to evaluate the relationship of UCN1 and ADM with various clinical parameters, and to assess UCN1 and ADM as diagnostic markers in HF, in comparison with pro-brain natriuretic peptide (pro-BNP).

Surgical extraction of an embolized atrial septal defect occluder device into pulmonary artery after percutaneous closure.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade.
