BACKGROUND Pulmonary vein isolation (PVI) for atrial fibrillation is associated with a transient increased risk of thromboembolic and hemorrhagic events. We hypothesized that dabigatran can be safely used as an alternative to continuous warfarin for the periprocedural anticoagulation in PVI. METHODS AND RESULTS A total of 999 consecutive patients(More)
The Internet crucially depends on the Domain Name System (DNS) to both allow users to interact with the system in human-friendly terms and also increasingly as a way to direct traffic to the best content replicas at the instant the content is requested. This paper is an initial study into the behavior and properties of the modern DNS system. We passively(More)
BACKGROUND Atrial fibrillation (AF) ablation is increasingly used in clinical practice. We aimed to study the natural history and long-term outcomes of ablated AF. METHODS AND RESULTS We followed 831 patients after pulmonary vein isolation (PVI) performed in 2005. We documented clinical outcomes using our prospective AF registry with most recent update on(More)
BACKGROUND A novel technology incorporates electrodes into an iPhone case that records an electrocardiographic tracing. OBJECTIVES The objectives of this study were to examine the feasibility and efficacy of this technology to monitor patients after the atrial fibrillation (AF) ablation procedure and to assess patients' feedback on its ease of use.

BACKGROUND The best periprocedural anticoagulation strategy at the time of pulmonary vein isolation (PVI) is not known. Most centers stop administering warfarin (Coumadin) and use bridging with heparin or enoxaparin. OBJECTIVE The purpose of this study was to evaluate the efficacy and safety of PVI under therapeutic international normalized ratio (INR).(More)
Ten hemolytic reactions occurred in our outpatient hemodialysis unit over a 12-month period (December 1989 to December 1990). Eight patients were hospitalized and one died. All patients developed severe abdominal or back pain an average of 2.5 hours into a 4-hour hemodialysis session using a bleach/formaldehyde reprocessed hollow-fiber cupraphan dialyzer(More)
BACKGROUND Plasma B-type natriuretic peptide (BNP) is abnormally elevated in patients with lone atrial fibrillation (AF). The exact significance and prognostic implications of this elevation have yet to be determined. Little is known about BNP in lone AF patients undergoing arrhythmia ablation. We sought to determine the relationship between BNP levels and(More)
BACKGROUND It is difficult to predict adverse patient outcomes associated with transvenous lead extraction (TLE) procedures. OBJECTIVE The purpose of this study was to examine the safety and efficacy of chronic endovascular pacemaker and implantable cardioverter-defibrillator (ICD) lead extraction and risk factors associated with adverse patient outcomes.(More)
INTRODUCTION The Hansen robotic system has only recently been used in the United States for catheter ablation procedures in humans. Atrial fibrillation (AF) ablation may be performed utilizing this system. We report our management of complications with early experience of this system. METHODS AND RESULTS All 71 patients in whom the system was utilized(More)
BACKGROUND The Evolution mechanical dilator sheath is a new lead extraction tool that uses a rotational mechanism and a bladed tip to overcome fibrosis. OBJECTIVE The purpose of this study was to report our initial experience with the Evolution system. METHODS Between March 2008 (our first use of Evolution) and September 2009, the Evolution sheath was(More)
