Risk of new-onset atrial fibrillation and stroke after radiofrequency ablation of isolated, typical atrial flutter
Radiofrequency ablation (RFA) is considered a curative procedure for typical atrial flutter (AFL); however, patients remain at risk for developing new atrial fibrillation (AF).

Initial experience with post Lariat left atrial appendage leak closure with Amplatzer septal occluder device and repeat Lariat application
Left atrial appendage (LAA) ligation with the Lariat device is a therapeutic option to prevent thromboembolic stoke in patients with nonvalvular atrial fibrillation (AF) at high risk for systemic thromboembolization and bleeding related to use of anticoagulation. In rare cases, this procedure could leave the LAA incompletely ligated with continued risk of stroke.

Atrial fibrillation ablation: A death-defying endeavor?
Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice.1 In addition to reductions in functional status and quality of life, AF is associated with a significant risk of stroke (increased 5-fold compared to the general population).2 Moreover, because of a combination of altered hemodynamics, AV dyssynchrony, and progressive atrial and ventricular mechanical dysfunction the presence of AF is associated with a doubling in the risk of death independent of other known risk factors, when compared to non-AF controls.

Progress toward the prevention and treatment of atrial fibrillation: A summary of the Heart Rhythm Society Research Forum on the Treatment and Prevention of Atrial Fibrillation, Washington, DC, December 9–10, 2013
The Heart Rhythm Society convened a research symposium on December 9–10, 2013, in Washington, DC, that focused on the prevention of atrial fibrillation (AF) as well as AF-related stroke and morbidity. Attendees sought to summarize advances in understanding AF since a 2008 National Institutes of Health (NIH) conference on this topic1 and to identify continued knowledge gaps and current research priorities. The research symposium also sought to identify key deficiencies and opportunities in research infrastructure, operations, and methodologies.

Pacing for treatment and prevention of atrial fibrillation: Is there an end to this story?Editorial Commentary
Pacemakers are frequently implanted in patients with atrial fibrillation (AF), which is the most common sustained cardiac arrhythmia with causal association with stroke, heart failure, cardiomyopathy, and all-cause mortality.1–5 In a general pacemaker population, AF can also develop frequently and progressively over time.6 Thus, as no surprise, the story of “pacing and AF” has been going around for a long time.1–7 The article by Padeletti et al8 in this issue of HeartRhythm perhaps adds a new twist.

2015 ACC/HRS/SCAI Left Atrial Appendage Occlusion Device Societal Overview
Left atrial appendage (LAA) occlusion devices have the potential to influence the clinical approach to stroke prevention in patients with atrial fibrillation (AF). A number of percutaneous techniques have been proposed, including intracardiac plugs and external ligation. Several devices have been adopted to various degrees in the United States and internationally. Only 1 (WATCHMAN, Boston Scientific, Marlborough, Massachusetts) has been evaluated in randomized controlled trials compared with the current standard of care.
