BACKGROUND: Reducing readmission after catheter ablation (CA) in atrial fibrillation (AF) is important. METHODS AND RESULTS: We utilized National Readmission Data (NRD) 2010-2014. AF was identified by International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) diagnostic code 427.31 in the primary field, while first CA of AF was identified via ICD-9 -procedure code 37.34. Any admission within 30 or 90 days of index admission was considered a readmission...

Flecainide, a class Ic antiarrhythmic, is used for the prevention of paroxysmal supraventricular tachycardia, paroxysmal atrial fibrillation/flutter, and sustained ventricular tachycardia. Flecainide is primarily metabolized by the liver and to a lesser extent (30%) is excreted unchanged in the kidney. We present a case of flecainide toxicity in the setting of renal impairment that was successfully treated with intravenous sodium bicarbonate.

Radiofrequency catheter ablation of the cavotricuspid isthmus is a proven therapy for typical atrial flutter (AFl); however, in some patients, new atrial arrhythmias (AA) may occur after AFl ablation. This study explored the difference in the occurrence of spontaneous AA after AFl ablation as a function of the patient's presenting rhythm on the day of the AFl ablation. A retrospective study of consecutive patients who underwent AFl ablation at Baylor University Medical Center at Dallas was performed. A total of 188 subjects were included; 50% (94) presented in AFl (Group AFl) on the day of the ablation procedure and 94 presented in sinus rhythm (SR; Group SR)...

BACKGROUND: Chagas disease (CD) is a major public health concern in Latin America and a potentially serious emerging threat in non-endemic countries. Although the association between CD and cardiac abnormalities is widely reported, study design diversity, sample size and quality challenge the information, calling for its update and synthesis, which would be very useful and relevant for physicians in non-endemic countries where health care implications of CD are real and neglected. We performed to systematically review and meta-analyze population-based studies that compared prevalence of overall and specific ECG abnormalities between CD and non-CD participants in the general population...

OBJECTIVES: Atrial tachyarrhythmia, including atrial fibrillation (AF), atrial flutter (AFL) and intra-atrial reentrant tachycardia (IART), occur frequently in patients with congenital heart disease (CHD), who may undergo multiple surgical procedures throughout life. However, data on the effectiveness of concomitant arrhythmia surgery in CHD patients are scarce. METHODS: Outcome of concomitant arrhythmia surgery for AF or AFL/IART was examined in 66 successive patients [31 men (47%); age at surgery: 56 ± 14 (24-78) years] with various CHD...

BACKGROUND: Spatial scan statistics have been used for the identification of geographic clusters of elevated numbers of cases of a condition such as disease outbreaks. These statistics accompanied by the appropriate distribution can also identify geographic areas with either longer or shorter time to events. Other authors have proposed the spatial scan statistics based on the exponential and Weibull distributions. RESULTS: We propose the log-Weibull as an alternative distribution for the spatial scan statistic for time to events data and compare and contrast the log-Weibull and Weibull distributions through simulation studies...

BACKGROUND: Proper visualization has always been the cornerstone for conducting proper cardiac interventions. Although many incisions have been described for mitral valve exposure, the feasibility of some comes at the expense of proper exposure. When it comes to a small left atrium, larger incisions may venture into critically situated structures, creating a heavy toll of increased morbidity and mortality. We aim to evaluate the safety and efficacy of a superior left atrium approach for mitral valve interventions and left atrial mass resection, particularly in a small left atrium...

BACKGROUND: Pediatric heart transplant recipients are at an elevated risk for development of atrial tachycardia (AT) however the underlying mechanisms and long-term outcomes are unclear. OBJECTIVE: We hypothesized that occurrence of AT in pediatric heart transplant recipients would be associated with a higher frequency of adverse events during follow-up. METHODS: A single center retrospective review of all pediatric heart transplant recipients with suspected AT between 1997 and 2017 was performed...

BACKGROUND: Controlled randomized trials (CRTs) comparing the efficacy of patent foramen ovale (PFO) closure and medical therapy in patients with cryptogenic stroke have yielded heterogeneous results. No data are available on the net clinical benefit with the two strategies. METHODS: We pooled data of 3440 patients enrolled in five CRTs, randomized to PFO closure (n = 1829) or medical therapy (n = 1611) and followed for a mean of 4.1 years. RESULTS: The net composite endpoint of stroke, major bleeding or atrial fibrillation (AF)/flutter was not different among PFO closure and medical therapy (OR 1...

BACKGROUND: Despite studies demonstrating the accuracy of smart watches (SW) and wearable heart rate (HR) monitors in sinus rhythm, no data exists regarding their utility in arrhythmias. METHODS: 102 hospitalized patients were evaluated at rest using continuous electrocardiogram (ECG) monitoring with concomitant SW-HR (FitBit, FB, Apple Watch, AW) for 30 min. RESULTS: Across all devices, 38,616 HR values were recorded. Sinus rhythm cohort demonstrated strong agreement for both devices with a low bias (FB & AW Bias = 1 beat)...

INTRODUCTION: Data on long-term outcomes of cryoballoon ablation for treatment of atrial fibrillation (AF) are sparse. Here, we report the first 5-year follow-up results and predictors of outcome for pulmonary vein isolation (PVI) using the second-generation cryoballoon (CB-Adv) in patients with symptomatic AF. METHODS AND RESULTS: For this prospective observational study, we enrolled 178 patients with paroxysmal (132/178 [74.2%] patients) or persistent AF who underwent PVI with CB-Adv at our institution during 2012...

OBJECTIVES: Atrial fibrillation (AF) is a major risk factor for stroke, which is the leading cause of cardiovascular mortality in sub-Saharan Africa. However, there is limited population-based epidemiological data on AF in sub-Saharan Africa. We sought to estimate the prevalence and correlates of AF in rural Uganda. METHODS: We conducted a cross-sectional study using community health fairs in 2015 targeting eight villages in rural Uganda. Study participants completed a medical history, a clinical exam, blood collection, and 12‑lead electrocardiographic (ECG) screening...

BACKGROUND: The electrocardiographic and intracardiac activation features of left atrial roof-dependent macroreentrant flutter have been incompletely characterized. METHODS: Patients post-pulmonary vein (PV) isolation with roof-dependent atrial flutter based on activation and entrainment mapping were included. ECG and coronary sinus activation were compared with mitral annular (MA) flutter. RESULTS: The roof-dependent left atrial flutter circled the right PVs in 32 of 33 cases...

BACKGROUND: Advancements in electrophysiology 3D mapping systems facilitate the broadening scope of electrophysiology study and catheter ablation to treat complex arrhythmias. While electroanatomical mapping systems have default settings available for a variety of mapping parameters, significant operator customization driven by arrhythmia type and experience can occur. However, multicenter comprehensive reporting of customized mapping settings is lacking. METHODS: In this prospective, multicenter observational registry, subjects with cardiac arrhythmias underwent electrophysiology study and ablation procedure using the EnSite Precision™ electroanatomical mapping system per standard of care, and associated automated mapping thresholds and procedural characteristics were observed...

BACKGROUND: The efficacy of patent foramen ovale (PFO) closure for secondary stroke prevention in cryptogenic stroke (CS) patients with PFO is uncertain. This meta-analysis aims to assess whether PFO closure is superior to medical therapy. METHODS: Pooled estimates were calculated using Revman 5.3. The two primary endpoints were stroke and transient ischemic attack (TIA). Secondary outcomes included all-cause mortality, new-onset atrial fibrillation or flutter, major bleeding and any adverse event...

Atrial fibrillation and atrial flutter (AF/AFL) are associated with an increased risk of stroke and systemic embolism. However, many patients are not started on guideline-recommended oral anticoagulation (OAC). We determined factors associated with initiation of OAC in eligible patients presenting to emergency departments. This retrospective cohort included patients with electrocardiogram (ECG)-documented AF/AFL presenting to 4 urban emergency departments in 2015. Presenting diagnoses, admission status, and comorbidities were determined by chart review...
