B-ab17-01 left atrial closure device thrombosis is associated with systemic embolization
Cardioembolic stroke and systemic embolism (CS/SE) represents the most severe complication of atrial fibrillation. Approximately 92% of intracardiac thrombosis originates from the left atrial appendage (LAA) and, although  its mechanical occlusion is a proved method to prevent cardioembolism, thrombosis of all types of LAA occlusion devices and their associations with CS/SE were observed.

B-ab07-02 spontaneous fluctuations in atrial fibrillation burden in patients with implantable devices: implications for incorporating burden into stroke risk assessment
Studies have tried to improve atrial fibrillation (AF) stroke prediction by incorporating AF burden, typically measured at a single time point.

B-ab05-04 telemedicine atrial fibrillation care: an integrative review
Atrial Fibrillation is a global phenomenon associated with an embolic stroke risk, decreased functional capacity, and worsening quality of life. An episode of atrial fibrillation can be highly symptomatic for patients and many rely on the emergency department for care even though it is often not a genuine medical emergency. Increasing patient access to specialty atrial fibrillation specialists via telemedicine has the potential to improve patient care.

B-ab03-04 cerebral microembolic signal burden during pulsed filed ablation: preliminary results from robotically assisted transcranial doppler
Transcranial Doppler (TCD) has been used to monitor the burden of cerebral microembolic signals (MESs) during atrial fibrillation (AF) ablation. MES burden is considered a surrogate marker for stroke risk and has never been reported during AF ablation with the novel pulsed field ablation (PFA) system.

B-po01-019 coagulation potential, electrophysiological characteristics and structural remodeling due to atrial fibrillation in young and aged goats
Age is a risk factor for atrial fibrillation (AF) as well as for stroke in patients with AF. The effect of ageing on AF mechanisms and on coagulation activity is not well understood.

B-po05-209 pericardial effusion after left atrial appendage occlusion resulting from an aortic dissection
Atrial fibrillation (AF) affects 2.3 million Americans. In those unfit for long-term anticoagulation, left atrial appendage occlusion (LAAO) is an alternative for stroke prophylaxis.

B-po05-199 differences in stroke or systemic thromboembolism readmissions after hospitalization for atrial fibrillation or atrial flutter
Although atrial fibrillation (AF) and atrial flutter (AFL) are different arrhythmias, they are assumed to confer the same risk of stroke and systemic thromboembolism (STE) despite a lack of available evidence.

B-po05-197 increased use of direct-acting oral anticoagulants and anticoagulation rates in a large health care system
Oral anticoagulation (OAC) has been underused in patients with atrial fibrillation (AF) at risk for stroke. Data from registries has shown OAC rates in eligible patients of 50-60%. The use of direct oral anticoagulants (DOACs) has improved OAC rates but contemporary data are lacking.

B-po05-154 an updated meta-analysis comparing left atrial appendage closure and oral anticoagulation
Left atrial appendage closure (LAAC) trials such as PREVAIL and PROTECT revealed non-inferiority of LAAC compared to warfarin. The recently published PRAGUE study showed that LAAC was non-inferior to direct oral anti-coagulants. Current guidelines give a IIb recommendation for LAAC in patients with non-valvular atrial fibrillation (NVAF) with increased risk of stroke and contraindication to long-term anticoagulation.

B-po05-153 quarterly versus annual ecg screening for atrial fibrillation in older chinese
Screening for atrial fibrillation before symptoms manifested and subsequent initiation of oral anticoagulants (OACs), could prevent stroke and death. The most cost-effective strategy to screen atrial fibrillation in high-risk population aged 65 and over remains unknown.

B-po05-144 comparing sodium glucose cotransporter 2 inhibitors and dipeptidyl peptidase-4 inhibitors on new-onset atrial fibrillation and ischemic stroke
Given the susceptibility of patients with type 2 diabetes mellitus towards cerebrovascular complications, there is increasing research on the cerebrovascular-protective effects of novel anti-diabetic agents. However, few studies have compared sodium glucose cotransporter-2 inhibitor (SGLT2I) and dipeptidyl peptidase-4 inhibitor (DPP4I) in their effects on stroke and atrial fibrillation (AF).

B-po05-142 atrial fibrillation patient with low cha2ds2vasc score may still benefit from oral anticoagulation therapy for ischemic stroke prevention: the need to refine stroke risk assessment scores
The CHA2DS2VASC score has shown limitations in the assessment of ischemic stroke (IS) risk in atrial fibrillation (AF) patients.

B-po05-139 changes in flow dynamics due to persistent atrial fibrillation in a chronically paced canine model
Atrial Fibrillation (AF) increases the risk of stroke, presumably because poor left atrial (LA) contraction leads to impaired blood flow and the potential for clots to form. Previous studies have not looked at flow changes over the course of AF progression.

B-po05-086 structural and tissue remodeling of the left atrium and left atrial appendage after atrial fibrillation ablation
Large left atrium appendage (LAA) orifice area and an increased left atrium (LA) volume have been associated with an increased risk of ischemic stroke. Catheter ablation (CA) of atrial fibrillation (AF) leads to anatomical and tissue changes within the LA and LAA.
