Circulation: Arrhythmia and Electrophysiology: 10/1/13 Bachmann’s bundle (BB), also known as the interatrial bundle, is well recognized as a muscular bundle comprising of parallel aligned myocardial strands connecting the right and left atrial walls and is considered to be the main pathway of interatrial conduction.1 Disruption of the bundle’s structure causes interatrial conduction block (IAB),2 which is associated […]

Arteriosclerosis, Thrombosis, and Vascular Biology: September 12, 2013 Objective—Atrial fibrillation (AF) and atherosclerotic vascular disease are closely entangled disorders and often coexist. Whether atherosclerosis predisposes to the development of AF has not been fully elucidated. Approach and Results—This study was performed within the framework of the Bruneck Study, a population-based survey with near-complete participation (932 of […]

Circulation: Arrhythmia and Electrophysiology: August 31, 2013 Background—Few clinical indices identify the propensity of patients to atrial fibrillation (AF) when not in AF. Repolarization alternans has been shown to indicate AF vulnerability, but is limited in its sensitivity to detect changes in action potential (AP) duration (APD), which may be subtle. We hypothesized that spectral analysis […]

CIRCULATIONAHA: October 8, 2013 Background—As the association between atrial fibrillation (AF) and race has only been rigorously compared in population-based studies that dichotomized participants as White or Black, it is unclear whether White race confers elevated AF risk or Black race affords AF protection. Methods and Results—The Healthcare Cost and Utilization Project was used to […]

Springer: 10/8/13 This study was conducted to examine the outcomes in patients with prior stroke/transient ischemic attack (CVA/TIA) after atrial fibrillation (AF) ablation and the feasibility of discontinuing oral anticoagulation (OAC). Methods This study examined long-term outcomes following AF ablations in 108 patients with a history of prior thromboembolic CVA/TIA. Because of risks of OAC, we […]

JACC: 10/1/13 A Translational Proof-of-Concept Study in Patients With Metabolic Syndrome in Whom Post-Operative Atrial Fibrillation Develops Objectives This study sought to provide bedside evidence of the potential link between cardiac mitochondrial dysfunction and arrhythmia as reported in bench studies. Background Atrial fibrillation (AF) is a frequent complication of cardiac surgery. Underlying mechanisms of post-operative atrial fibrillation (POAF) remain largely unknown. […]

J Am Coll Cardiol: 10/1/13 Persistent iatrogenic atrial septal defect (iASD) after transseptal puncture for radiofrequency (RF) ablation of atrial fibrillation (AF) using 8-F sheaths has been reported at rates of 0 to 19% at medium-term follow-up, depending on the transseptal puncture technique, the follow-up interval, and whether transthoracic echocardiography (TTE) or transesophageal echocardiography was used for […]

PLOS: 10/8/13 Access to unpublished clinical study reports (CSRs) is currently being discussed as a means to allow unbiased evaluation of clinical research. The Institute for Quality and Efficiency in Health Care (IQWiG) routinely requests CSRs from manufacturers for its drug assessments. Our objective was to determine the information gain from CSRs compared to publicly available […]

STROKEAHA: October 8, 2013 Background and Purpose—Organized stroke systems of care include Primary Stroke Center (PSC) certification and preferential emergency medical services (EMS) routing of suspected patients with stroke to designated PSCs. Stroke EMS routing is not nationally governed; in California, routing is determined by county. EMS routing policies might provide an incentive for PSC accreditation. […]
