AIMS Atrial fibrillation ablation requires peri-procedural oral anticoagulation (OAC) to prevent thromboembolic events. There are several options for OAC. We evaluate peri-procedural AF ablation complications using a variety of peri-procedural OACs. METHODS AND RESULTS We examined peri-procedural OAC and groin, bleeding, and thromboembolic complications(More)
PURPOSE The purpose of this study was to evaluate how atrial fibrillation (AF) ablation has evolved over time with regards to patient characteristics, procedural variables, complications, and outcomes. METHODS We evaluated trends over time from 2003 to 2010 in clinical characteristics, procedural variables, complications, and Kaplan-Meier AF-free rates(More)
AIMS Atrial fibrillation (AF) ablation is generally performed after patients fail antiarrhythmic drug (AAD) therapy. Some patients have drug contraindications or choose to avoid a lifetime of drug therapy. Little is known about the impact of previous drug therapy on ablation outcomes. We evaluated AAD use before AF ablation and its impact on ablation(More)
PURPOSE Atrial fibrillation (AF) ablation uses expensive technology and equipment. Physicians have considerable latitude over equipment choice. Average Medicare reimbursement is $10,338 for uncomplicated AF ablations. The purpose of this study is to evaluate the cost of special equipment chosen by physicians to perform AF ablation. METHODS We obtained the(More)
The currently available automatic implantable cardioverter-defibrillator has proven highly successful for termination of ventricular tachycardia and fibrillation. Newer devices, however, permit lower energy shocks to be delivered initially and longer episodes of arrhythmia to occur before shocks are delivered. These changes may result in longer durations of(More)
PURPOSE 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(More)
PURPOSE The purpose of this study was to evaluate ultra high density-activation sequence mapping (UHD-ASM) for ablating atypical atrial flutters. METHODS For 23 patients with 31 atypical atrial flutters (AAF), we created UHD-ASM. RESULTS Demographics age = 65.3 ± 8.5 years, male = 78%, left atrial size = 4.66 ± 0.64 cm, redo ablation 20/23(87%). AAF(More)
AIMS Atrial fibrillation (AF) is associated with a high incidence of strokes/thromboembolism. The CHADS2 score assigns points for several clinical variables to identify stroke risk. The CHA2DS2-VASC score uses the same variables but also incorporates age 65 to 74, female gender, and vascular disease in an effort to provide a more refined risk of(More)
