conclusions we can conclude that treatment of af using a right-sided minithoracotomy approach and rf energy in patients undergoing cardiac surgery for various valve diseases is feasible, safe, and reproducible. objectives our aim is to evaluate the feasibility, safety, and immediate plus medium-term results of concomitant af ablation therapy in patients undergoing minimally invasive valve surge...
Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...

introduction: the aim of the present study was to determine direct effects of no modulation on protective electrophysiological properties of atrioventricular node (av node) in the experimental model of af in rabbit. methods: isolated perfused rabbit av nodal preparations were used in two groups. in the first group (n=7), lname (50μm) was applied. in the second group (n=12), different concentrat...

Background: Alcohol consumption has multiple side effects on heart which can be divided to six subgroups: Heavy alcohol drinkers (80 g/day alcohol consumption) are most susceptible to cardiac complications. The aim of this study was to review alcohol side effects on heart and two present two alcoholic patients with alcoholic cardiomyopathy. Case report: Case A: A 52 year-old man presented with ...
Background: Lack of attention to standardized guidelines has caused tragic outcome in patients with atrial fibrillation and ultimately increase of financial burden imposed on the community structure of the economic system. Therefore, the present study was aimed to assess the exposure of patients with atrial fibrillation. Methods: A total of 506 patients with atrial fibrillation were...
Background: Coronary artery bypass graft surgery (CABG) with cardiopulmonary bypass pump may cause systemic inflammatory reactions by releasing cytokines which leads to multiple organ failure. Vitamin C has anti-inflammatory and antioxidant properties. The study aimed to determine the effect of vitamin C on inflammatory markers and atrial fibrillation in patients undergoing CABG. Materials and ...
Background: The 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhi-bitors (statins) have revolutionized the treatment of hypercholesterolemia. Some evide-nce indicated the role of nodal refractoriness and concealed conduction in anticipating the ventricular rate during atrial fibrillation. Recent evidence has indicated that statins can reduce the incidence of both supraventricular a...
diabetic mellitus (dm) is a major risk factor of morbidity, mortality and economic cost to society. diabetic patients are at risk of having microvascular or macrovascular disorders of diabetes. postoperative anemia have wide spectrum of some early complications that require more care in hospitalization stays. therefore, this study was designed to evaluate effect of preoperative anemia on short-...
