Atrial Fibrillatory Wall Motion and Degree of Atrial Remodeling in Patients with Atrial Fibrillation: A Tissue Velocity Imaging Study
Journal of Cardiovascular Electrophysiology, 10/28/2009

Catheter Ablation of Supraventricular Arrhythmias and Atrial Fibrillation
American Family Physician, 11/12/2009

Shapira AR – Supraventricular arrhythmias are relatively common, often persistent, and rarely life–threatening cardiac rhythm disturbances that arise from the sinus node, atrial tissue, or junctional sites between the atria and ... and atrial flutter. The term "supraventricular tachycardia" commonly refers to atrial tachycardia, atrioventricular nodal reentrant tachycardia, and atrioventricular reciprocating tachycardia, an entity that includes Wolff–Parkinson–White syndrome. Atrial fibrillation is a distinct ... at initial diagnosis, when symptoms develop, or if medical therapy fails. Catheter ablation of supraventricular tachycardias, atrial flutter, and atrial fibrillation offers patients high effectiveness rates, durable (and often permanent) therapeutic end points, and low complication rates ... tachycardia, supraventricular atrial fibrillation [more...]

Sudden atrial fibrillation associated with acute alcohol ingestion and cor triatriatum
Baylor UMC Proceedings, 10/27/2009

Falcone AM et al. – This is the only reported case of alcohol–induced atrial fibrillation in a patient with the finding of cor triatriatum. It is unknown whether there is an association between the ... disorders. Given that both alcohol consumption and cor triatriatum are associated with atrial fibrillation, it is unclear if the presence of the congenital abnormality put the patient at a higher risk of arrhythmias. He has been counseled to reduce his alcohol intake. At 6–month follow up, the ... monitored for further arrhythmias or symptoms of obstruction. [more...]

Oral anticoagulant therapy safely prevented stroke in older patients with atrial fibrillation
Evidence-Based Medicine, 10/26/2009

Dunn A – In patients with atrial fibrillation, the effectiveness of antiplatelet therapy for stroke prevention decreased with age, but that of oral anticoagulants did not. Relative risk of serious ... an oral anticoagulant (OAC) with an antiplatelet (AP). Patients: 8932 adults (mean age 72 y, 63% men) with non–valvular atrial fibrillation. Patients with clinical indications for or against any of the active therapies were excluded. Interventions: full–dose OACs ... treatment with either drug on serious bleeding or cardiovascular events.

Glucocorticoid Use and Risk of Atrial Fibrillation or Flutter
Archives of Internal Medicine, 10/14/2009

Christiansen CF et al. – Current glucocorticoid use was associated with an almost 2–fold increased risk of atrial fibrillation or flutter. [more...]

Atrial fibrillation: from ion channels to bedside treatment options
Journal of Electrocardiology, 11/05/2009

Singh B et al. – The purpose of this article is to review the role of ion channels in the development of atrial fibrillation and discuss the nature of their inhibition by investigational antiarrhythmic agents. Novel ... atrial–selective compounds (eg, vernakalant), multichannel blocking agents (eg, tedisamil), and gap junction modifiers (eg, rotigaptide). Targeted antiarrhythmic therapies have the potential to provide safer and more effective management options for patients with atrial fibrillation ... cardiology,arrhythmias/ep [more...]

Thromboaspiration of left atrial clot during ablation of atrial fibrillation
Europace, 10/19/2009

Latcu DG et al. – The authors describe a case during which a left atrial thrombus was visualized within the left atrium attached to a circular catheter during an atrial fibrillation ablation procedure. This was ... thromboaspiration using a steerable sheath, preventing a potential serious complication. [more...]

Low Level Vagosympathetic Stimulation: A Paradox and Potential New Modality for the Treatment of Focal Atrial Fibrillation
Circulation: Arrhythmia and Electrophysiology, 10/08/2009

Li S et al. – Low Level Vagosympathetic Stimulation may prevent episodic atrial fibrillation due to rapid PV and non–PV firing. [more...]

Atrial fibrillation is associated with increased risk of perioperative stroke and death from carotid endarterectomy
Journal of Vascular Surgery, 11/03/2009

Harthun NL et al. – Patients with atrial fibrillation have a substantially higher risk of stroke and death after carotid endarterectomy. [more...]

Pro-arrhythmia in atrial fibrillation suppression pacing algorithms
Europace, 10/19/2009

Ghanbari H et al. – Atrial overdrive pacing algorithms have been partially effective in controlling atrial fibrillation (AF). A 76–year–old man with history of a cardiomyopathy and paroxysmal AF underwent implant ... AF was demonstrated, but with inappropriate ICD shocks secondary to a typical AV nodal re–entrant tachycardia. After successful slow pathway modification, no further episodes were documented with suppression of his AF burden with PP algorithms enabled. [more...]
