BACKGROUND Atrial fibrillation ablation has made tremendous progress with respect to innovation, efficacy, and safety. However, limited data exist regarding the burden and trends in adverse outcomes arising from this procedure. The aim of our study was to examine the frequency of adverse events attributable to atrial fibrillation (AF) ablation and the(More)
BACKGROUND The occurrence of atrial fibrillation after ablation of type I atrial flutter remains an important clinical problem. To gain further insight into the pathogenesis and significance of postablation atrial fibrillation, we examined the time to onset, determinants, and clinical course of atrial fibrillation after ablation of type I flutter in a large(More)
A patient who presented with a new apparent seizure was found to have abnormal electrocardiographic findings, with classic features of the Brugada syndrome. He had spontaneous episodes of nonsustained ventricular tachycardia, easily inducible ventricular fibrillation at electrophysiological study in the absence of structural heart disease, and a negative(More)
The use of pacemakers and central venous catheters (CVC) has become commonplace in the field of medicine. In the past, superior vena cava (SVC) syndrome was almost always associated with malignant occlusion of the SVC. However, with the increased use of pacemakers and implantable cardioverter-defibrillators (ICDs) almost 30% of all cases are related to the(More)
BACKGROUND Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. The associated morbidity and mortality make AF a major public health burden. Hospitalizations account for the majority of the economic cost burden associated with AF. The main objective of this study is to examine the trends of AF-related hospitalizations in the United(More)
BACKGROUND Anticoagulation in cardioversion and ablation of atrial fibrillation is imperative for reducing thrombo-embolic events. Ample information is available about the use of warfarin and vitamin K antagonists (VKA) but few trials examine safety and efficacy of rivaroxaban in these procedures. We aim to explore the hypothesis that rivaroxaban causes(More)
INTRODUCTION The objective of our study was to assess the burden of arrhythmias, the gender differences in occurrence of arrhythmias and the impact of these arrhythmias on hospitalization outcomes in patients with Takotsubo Cardiomyopathy (TTC). METHODS TTC and various arrhythmias were identified using appropriate ICD-9-CM codes from Nationwide Inpatient(More)
OBJECTIVES Atrial fibrillation (AF) often develops in patients with multiple myeloma following autologous stem cell transplantation (ASCT), but the exact incidence of, and the risk factors for AF have not been described. In this study, we sought to determine the incidence of AF in patients with multiple myeloma undergoing ASCT. METHODS Patients who(More)
Previous studies have identified a "weekend effect" in terms of a poor outcome for patients hospitalized with various acute medical conditions. The aim of our study was to investigate whether weekend admissions for atrial fibrillation (AF) result in worse outcomes than those admitted on weekdays. In the Nationwide Inpatient Sample 2008 database, we(More)
