Ce-454029-4 racial disparities in the use of oral anticoagulation for atrial fibrillation by sex and within high and low stroke risk populations
Atrial fibrillation (AF) is the most common arrhythmia and is associated with an increased risk of ischemic stroke. Oral anticoagulation (OAC) has been shown to reduce the risk of ischemic stroke in patients with AF. Previous studies have demonstrated that both females and Black, Hispanic, and Asian groups are less likely to be prescribed OAC.

Morbid Obesity is Associated with Increased Procedural Complications and Worse In-Hospital Outcomes after Percutaneous Left Atrial Appendage Occlusion Device Implantation
Obesity has adverse effects on cardiovascular hemodynamics and is an independent risk factor for the induction and perpetuation of atrial fibrillation (AF) (1). Percutaneous left atrial appendage occlusion (LAAO) has shown promising results in reducing stroke risk in select AF patients who cannot be managed with a conventional long-term oral anticoagulation strategy (2). In the landmark PROTECT-AF trial evaluating the efficacy and safety of percutaneous LAAO, patients receiving LAAO device had a mean BMI of 31.6 kg/m2 (2), however, no distinct assessment of outcomes were conducted based on body weight.

Electrocardiographic P terminal force in lead V1, its components, and the association with stroke and atrial fibrillation or flutter
The electrocardiographic (ECG) marker P terminal force V1 (PTFV1) is generally perceived as a marker of left atrial pathology and has been associated with atrial fibrillation or flutter (AF).

Contemporary Trends in Utilization and Outcomes of Percutaneous Left Atrial Appendage Occlusion in the United States from 2016 to 2019
Atrial fibrillation is a major cause of stroke and thromboembolism and oral anticoagulation is the mainstay of prevention. In patients who are poor candidates for long-term anticoagulation, percutaneous left atrial appendage occlusion (pLAAO) emerged as an alternative stroke prevention strategy and was approved by the US FDA in 2015. We aimed to examine trends in procedural volume, resource utilization, and clinical outcomes of pLAAO from a nationally representative cohort.

Improving guideline-based anticoagulation in atrial fibrillation: A systematic literature review of prospective trials
Guidelines for anticoagulation in patients with atrial fibrillation (AF) aim to decrease the risk of ischemic stroke. However, there is a gap in actual practice between patients who have an indication for anticoagulation and those who are actually prescribed anticoagulation.

Performing Transcatheter Left Atrial Appendage Closure: Techniques and Challenges
The left atrial appendage (LAA) has been demonstrated to be the major source of thromboemboli in patients with atrial fibrillation (AF).1 The rationale of LAA closure is based on eliminating LAA continuity with the left atrium thereby reducing stroke risk. Indeed, left atrial appendage occlusion (LAAO) procedures play an important role in anticoagulation-intolerant patients at risk for AF-related stroke. Based on the PROTECT-AF2 and PREVAIL3 studies, the Food and Drug Administration (FDA) approved use of the Watchman (Boston Scientific, MA) device in 2015, with an updated generation of device subsequently ratified in 2020 ...

Anticoagulation Management and Risk of Thromboembolism in Healthy Youth with Atrial Fibrillation: Data from a Multi-Institutional PACES Collaborative Registry
Stroke is a well-defined complication of atrial fibrillation (AF) in adults. Risks and benefits of anticoagulation management in this patient population are extensively studied resulting in well-defined clinical practice guidelines.1 On the other hand, there is limited data in healthy children and young adults.

Atrial fibrillation after transcatheter patent foramen ovale closure: To measure is to know
A patent foramen ovale (PFO) results from an incomplete fusion of the septum primum and secundum at birth.1 The prevalence of a PFO in the adult population has been estimated at approximately 25%, but this rate was highly dependent on the diagnostic modality used and selection bias by including a disproportionate number of patients with previous cryptogenic stroke in comparative studies.2 The causal relation between cryptogenic stroke and the presence of a PFO has long been debated, yet with rates up to 40% the prevalence for PFOs is significantly higher in patients with cryptogenic stroke.

Po-625-05 electrocardiographic deep terminal negative of the p wave in v1 and ischemic stroke:the atherosclerosis risk in communities (aric) study
Abnormal P-wave indices are associated with ischemic stroke independent of atrial fibrillation (AF). Deep terminal negative of the P wave in V1 (DTNPV1) is a simple ECG index that reflects underlying left atrial remodeling. However, it is unknown whether DTNPV1 is associated with ischemic stroke.

Po-718-05 prescribing patterns of direct anticoagulants versus vitamin k antagonists in patients with non-valvular atrial fibrillation and extreme obesity
Anticoagulation is an effective treatment in prevention of stroke in patients with atrial fibrillation (AF). Direct anticoagulants (DOACs) have been favored over vitamin K dependent antagonists (VKAs) given their safety and efficacy. However, there is limited real-world data on DOAC use among patients with extreme obesity.
