B-po05-059 left atrial appendage occlusion (laao) using watchman device in end stage renal disease: analysis from national inpatient sample
Percutaneous occlusion of left atrial appendage (LAAC) using WATCHMAN device is a widely accepted alternative to oral anticoagulants to prevent ischemic stroke in atrial fibrillation. There is limited data regarding the utilization and safety of this intervention in patients with ESRD.

B-po04-143 safety and feasibility of reactive atrial-based anti-tachycardia pacing algorithm in cardiovascular implantable electronic devices to suppress atrial fibrillation in patients with left atrial appendage closure device
Reactive atrial-based anti-tachycardia pacing (rATP) in CIED (cardiovascular implantable electronic devices) are effective in AF suppression. Uninterrupted systemic anticoagulation is mandated when these algorithms are activated to avoid stroke and systemic thromboembolism. However, the use of rATP algorithm in patients with left atrial appendage (LAA) closure device without ongoing anticoagulation has not been studied.

B-po04-141 left atrial appendage occlusion versus oral anticoagulation as primary strategies to prevent laa thrombus and stroke following left atrial appendage electrical isolation: apropensity score-matched analysis
Left atrial appendage electrical isolation (LAAEI) has been shown to be an effective strategy in catheter ablation (CA) for atrial fibrillation (AF). However, its widespread adaptability is limited because patients must be on lifelong oral anticoagulation (OAC) irrespective of their CHA2DS2VASc score and due to some concerns about increased risk of thromboembolic events (TE) despite OAC.

B-po04-053 anticoagulation guided by long-term ecg monitoring using an implantable loop recorder following cryoballoon pulmonary vein isolation in patients with atrial fibrillation
Cryoballoon (CB) pulmonary vein isolation (PVI) is used in patients with atrial fibrillation (AF). Current clinical guidelines recommend continued oral anticoagulation (OAC) in patients (pts) at a high risk of stroke, irrespective of ablation outcome. However, these guidelines do not account for our ability to objectively monitor pts for AF recurrence post-ablation.

B-po03-156 procedural complications and in-hospital outcomes from left atrial appendage occlusion device implantation in patients with chronic and end stage renal disease
The Watchman device has emerged as an alternative strategy to oral anticoagulation for mitigating ischemic stroke risk in selected patients with atrial fibrillation (AF), but safety data in patients with kidney disease are limited.

B-po03-155 outcomes of left atrial appendage occlusion with watchman in contemporary clinical practice compared with clinical trials: a pooled analysis of protect-af, prevail, and the ncdr laao registry
The PROTECT-AF and PREVAIL trials  established Watchman left atrial appendage occlusion (LAAO) as an alternative to warfarin for stroke protection in atrial fibrillation. In clinical practice, LAAO is often performed in patients who cannot tolerate long-term anticoagulation and have more cardiac and non-cardiac comorbidities.

B-po03-152 left atrial appendage occlusion in patients with intracranial hemorrhage
Patients with prior intracranial hemorrhage (ICH) and atrial fibrillation (AF) are at increased risk of recurrent bleeding; and often not treated with oral anticoagulation despite high risk of ischemic stroke.

B-po03-108 combined minimally invasive approach to left atrial ablation (convergent procedure) with left atrial appendage clip for persistent atrial fibrillation
Atrial fibrillation (AF) is a major cause of structural heart disease, stroke, with increased hospitalizations. Patients can require multiple procedures and anti-arrhythmics to maintain sinus rhythm (SR). Patients with AF refractory to pharmacological and catheter ablations can be offered the Convergent Procedure. Traditional endocardial ablation is combined with a staged epicardial ablation via a subxiyphoid direct approach for radiofrequency lesion placement on the posterior left atrial wall. The left atrial appendage (LAA) occlusion is achieved with clip application (AtriClip LAA exclusion system, AtriCure, Mason, OH, USA).

B-po02-052 device detected atrial fibrillation: anticoagulation rates in patients undergoing intensive remote monitoring
Remote monitoring (RM) allows for the early detection of atrial fibrillation (AF), providing an opportunity to evaluate the need for anticoagulation for stroke prevention.

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-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-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.

Letter to the Editor —Clinical phenotypes in AF trials
Yang et  al1 conducted a retrospective study of the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial. Their findings did not support the first primary Early Treatment of Atrial Fibrillation for Stroke Prevention Trial (EAST-AFNET 4) outcome.2 Clinical phenotypes of atrial fib rillation (AF) should be considered.
