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-po03-153 left atrial appendage occlusion in patients with persistent thrombus: a case series
Percutaneous left atrial appendage (LAA) closure is contraindicated in patients with persistent LAA thrombus. This leaves a small number of patients at very high risk of future stroke. There are no established alternatives to treat these patients.

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-po03-151 left atrial appendage occlusion as alternative approach for stroke prevention in hereditary hemorrhagic telangiectasia patients with atrial fibrillation
In this study, we evaluate the safety and efficacy of left atrial appendage occlusion (LAAO) for stroke prevention in HHT.

B-po03-148 risk stratification for ischemic stroke and major bleeding in patients without atrial fibrillation - validity of cha2ds2-vasc and has-bled score
Atrial fibrillation (AF) is the most common arrhythmia. Recent cardiac implantable electronic devices (CIEDs) have led to an improvement in the early detection of AF episodes. ESC guidelines for the management of AF recommend the use of CHA2DS2-VASc score as class I to predict the risk of ischemic stroke in patients with AF. However, the validity of the CHA2DS2-VASc and HAS-BLED scores to predict ischemic stroke and major bleeding events in patients without AF remains unclear.

B-po04-077 heart rate variability and left atrial hemodynamics in atrial fibrillation measured with 4d flow mri
Atrial fibrillation (AF) can lead to stroke due to thrombus formation in the left atrium (LA) or left atrial appendage (LAA). Altered LA hemodynamics in the presence of AF may be predictive of thrombus and stroke risk. Previous 4D flow MRI studies found increased stasis and decreased peak velocity in patients with AF. However, the impact of variable R-R intervals on LA velocity and stasis measurement has not been investigated.

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.

EP News Clinical July 2021
Bernstein and colleagues (JAMA 2021; 325:2169-2177. PMID: 34061145) evaluated whether long term monitoring with an implantable cardiac monitor (ICM) is more effective than usual care for AF detection in patients with stroke from large- or small-vessel disease. Overall, 242 patients were randomized to ICM insertion within 10 days of the index stroke. Patients in the control group (n = 250) received site-specific usual care with external cardiac monitoring, such as 12-lead electrocardiograms, Holter monitoring, telemetry, or event recorders.

Early recurrence of atrial tachyarrhythmia post –atrial fibrillation ablation: Filling in the blank
Supported by the recent results of the Catheter Ablation vs Antiarrhythmic Drug Therapy for Atrial Fibrillation (CABANA) and Early Treatment of Atrial Fibrillation for Stroke Prevention (EAST-AFNET4) trials, catheter ablation is a preferable contemporary linchpin in the treatment of symptomatic atrial fibrillation (AF).1,2 Traditionally, the efficacy with ablation has been broadly defined by either objective arrhythmic recurrence such as atrial arrhythmias of over 30 seconds in duration or subjective recurrence of symptomatic arrhythmias.

EP News: Allied Professionals
In this multicenter, randomized trial (Whitlock et al. New Engl J Med. 2021;384:2081-91. PMID: 33999547), the investigators sought do determine whether surgical left atrial appendage occlusion (LAAO) prevents ischemic stroke in patients with atrial fibrillation (AF). Patients with AF and CHA2DS2-VASc score of at least 2 who were scheduled to undergo cardiac surgery were randomized on a 1:1 basis to surgical LAAO or no occlusion. The surgeon and surgical team were informed of the randomization, but teams taking care of the patient post-operatively including during long term follow-up, and who were charged with managing anti...
