Right atrial dilation due to left heart disease is a common complication among adults. The present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. The results of chest X-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. During the tra...

atrial fibrillation (af) is the most common complication of coronary artery bypass graft surgery (cabg). the reported incidence of af after cabg varies from 20% to 40%. postoperative af (poaf) is associated with increased incidence of hemodynamic instability, thromboembolic events, longer hospital stays, and increased health care costs. a variety of pharmacological and nonpharmacological strate...

background prolonged intensive care unit (icu) and hospital stay after cardiac surgery is vitally important and is influenced by both intraoperative and postoperative factors. objectives this randomized clinical trial study was designed to assess whether vitamin c supplementation could reduce the length of icu and hospital stay in post-cardiac surgery patients. patients and methods two hundred ...

background: atrial fibrillation (af) is the most common cardiac arrhythmia and an independent risk factor for stroke among the elderly. a role for inflammation in the atrial remodeling as well as development and recurrence of af is known. objective: to compare il-17a between patients with different types of af and healthy individuals. methods: il-17a was measured in sera of 112 patients and 107...

Atrial fibrillation affects at least 1% of the population and causes marked society-wide morbidity and mortality. Current management of atrial fibrillation including antithrombotic therapy and management of concomitant conditions in all patients, rate control therapy in most patients, and rhythm control therapy in patients with severe atrial fibrillation-related symptoms can alleviate atrial fi...

BACKGROUND Atrial fibrillation can be categorized into nonpermanent and permanent atrial fibrillation. There is less information on permanent than on nonpermanent atrial fibrillation patients. This analysis aimed to describe the characteristics and current management, including the proportion of patients with successful atrial fibrillation control, of these atrial fibrillation subsets in a larg...

Echocardiographic Findings That May Help Identify Occult Intermittent Atrial Fibrillation in Hypertensive Patients at Risk for a Second (or First) Ischemic Stroke To the Editor: In their review, Liao et al1 found that Holter or event monitoring of patients after ischemic stroke identified 5% to 7% with intermittent atrial fibrillation not present on the admission ECG. They suggest that such mon...

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...

Introduction: Electrophysiological studies have demonstrated a relationship between aging and atrioventricular (AV) nodal conduction and refractoriness. The aim of the present study was to determine the effects of nodal aging on dynamic AV nodal field potential recording during atrial fibrillation (AF) in rabbit. Methods: Two groups of male New Zealand rabbits (neonatal 2-week-olds and adult...
