Fatty acids in adipose tissue share dietary sources and metabolic pathways and therefore occur in patterns. The aim of the present study was to investigate the association between adipose tissue fatty acid patterns identified by the data-driven dimension-reducing method treelet transform and the risk of atrial fibrillation. A total of 57,053 Danish men and women aged 50-64 years participating in the Diet, Cancer and Health cohort had an adipose tissue biopsy taken at baseline. Read More

Atrial tachycardia and atrial flutter are frequent arrhythmia that occur spontaneously and after ablation of atrial fibrillation. Depolarization waves that differ significantly from sinus rhythm propagate across the atria with high frequency (typically 140 to 220 beats per minute). A detailed and personalized analysis of the spread of depolarization is imperative for a successful ablation therapy. Read More

Escape mapping is a novel technique that can be used to locate sites of persistent conduction and achieve exit block during an atrial fibrillation ablation. This method allows for mapping solely with the ablation catheter in the left atrium by annotating to a catheter in the coronary sinus. We illustrate the utility escape mapping during an atrial fibrillation ablation where entrance block is achieved without exit block. Read More

This report describes a case of isthmus-dependent atrial flutter ablation by the femoral approach in a 54-year-old woman with a previously unknown absence of the inferior vena cava (IVC) and dual chamber pacemaker. Despite looping of the catheters, ablation and termination of atrial flutter were performed successfully without function alteration of the pacemaker leads.  This is the first report of an inferior-to-superior approach for ablation of atrial flutter in the absence of the perihepatic IVC with the presence of chronic indwelling leads in the area targeted for radiofrequency.

Aims: Electrical cardioversion is still the preferred method to restore sinus rhythm in patients with atrial fibrillation. The main disadvantage is that electrical cardioversion requires deep sedation, generally administered by anaesthesiologists, for safety concern.

Left atrial appendage (LAA) thrombus in nonvalvular atrial fibrillation or flutter (AF) is a major cause of stroke and presents a therapeutic dilemma in a rhythm-control strategy.

This study sought to establish (1) the prevalence of LAA thrombus (2) the prevalence of LAA thrombus despite antithrombotic therapy, (3) the rate of persistence of LAA thrombus despite appropriate anticoagulant prescriptions, and (4) determinants of LAA thrombus persistence.

Department of Neurology, Weill Cornell Medical College, New York, NY (A.E.M., M.L.C., B.B.N., H.K.).

Background and Purpose- It is unclear whether atrial fibrillation/flutter (AF) newly diagnosed after ischemic stroke represents a preexisting risk factor that led to stroke, an arrhythmia triggered by poststroke autonomic dysfunction, or an incidental finding. Methods- We compared AF incidence after hospitalizations for ischemic stroke, hemorrhagic stroke, and nonstroke conditions using inpatient and outpatient claims between 2008 and 2015 from a nationally representative 5% sample of Medicare beneficiaries. We used validated International Classification of Diseases, Ninth Revision, Clinical Modification ( ICD-9-CM) codes to identify AF-free patients hospitalized with ischemic or hemorrhagic stroke and matched them in a 1:1 ratio by age, sex, race, calendar year, vascular risk factors, and Charlson comorbidities.
