Incidence of new-onset atrial fibrillation after transcatheter patent foramen ovale closure using 15 years of Ontario administrative health data
Individuals with patent foramen ovale (PFO) routinely undergo transcatheter closure (TC) for secondary prevention of recurrent stroke. However, some evidence suggests that TC may increase the risk of new-onset atrial fibrillation (AF).

EP News: Allied Professionals
In this non-prespecified, post hoc analysis of the AUGUSTUS (The Open-Label, 2 x 2 Factorial, Randomized, Controlled Clinical Trial to Evaluate the Safety of Apixaban vs. Vitamin K Antagonist and Aspirin vs. Placebo in Patients with Atrial Fibrillation and Acute Coronary Syndrome and/or Percutaneous Coronary Intervention) trial (Harskamp et al. J Am Coll Cardiol. 2022;79:417-27. PMID-35115097), the authors sought to evaluate whether the risk of bleeding or stroke as assessed by baseline HAS-BLED and CHA2DS2-VASc scores affected the results of the trial.

Procedural and Short-Term Follow-Up Outcomes of Amplatzer Amulet Occluder versus Watchman FLX Device: A Meta-Analysis
Left atrial appendage (LAA) occlusion provides effective protection against thromboembolic (TE) events in high-risk atrial fibrillation patients. Two percutaneous devices are currently available in the United States for stroke prophylaxis: the WatchmanTM device (Boston Scientific, USA) and the AmplatzerTM AmuletTM Left Atrial Appendage Occluder (Abbott, USA). The latter has recently received Food and Drug Administration approval as a result of the findings of the Amulet IDE randomized trial (1), which showed superiority for LAA occlusion (lower rates of leaks>5mm) based on a comparison between the second generation Amplatz...

EP News: Clinical
Singer et  al (JAMA Cardiol 2021;6:1364, PMID 34586356) evaluated the temporal association between episodes of atrial fibrillation (AF) and stroke in patients with cardiac implantable electronic devices (CIEDs). In a case-crossover study, data from an electronic health record database were linked with record s of patients with CIEDs. The prespecified duration of AF was ≥5.5 hours during days 1–30 vs days 91–120 prestroke. The main outcome was odds ratio (OR) for stroke comparing AF during days 1–30 vs days 91–120 prestroke.

Unequal prescription of anticoagulants among females and males with atrial fibrillation and similar stroke risk – should we omit sex category from the CHA2DS2-VASc score?
The CHA2DS2-VASc stroke risk score has been recommended by the European Society of Cardiology atrial fibrillation (AF) guidelines to guide decision on oral anticoagulation (OAC) prescription in AF patients. Whereas female sex was initially considered an individual risk factor warranting antithrombotic treatment in all female AF patients independent of other risk factors, this recommendation was revised as growing evidence showed that female sex is rather a risk modifier as sex does not contribute to stroke risk in the absence of other risk factors.

EP News: Clinical
Lakkireddy et  al (Circulation 2021;144:1543, PMID 34459659) evaluated the safety and effectiveness of the Amulet left atrial appendage occluder (A) compared with the Watchman device (W). Patients with nonvalvular atrial fibrillation at an increased risk of stroke were randomly assigned (1:1) to A or W. The prim ary end points included safety (composite of procedure-related complications, death, or major bleeding at 12 months) and effectiveness (composite of ischemic stroke or systemic embolism at 18 months).

B-po02-079 performance of atrial fibrillation burden patterns detected via insertable cardiac monitor for stroke risk stratification
Atrial fibrillation (AF) is associated with increased stroke risk, yet limitations in conventional monitoring restrict our understanding of AF burden risk thresholds. Predictive algorithms incorporating continuous monitoring data may be useful for stroke prediction.

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-po02-045 utility of a smartphone connected electrocardiogram recorder for detecting atrial fibrillation in post-stroke patients
Atrial fibrillation is one of the important causes of ischemic stroke. Routine 24-hour monitoring reveals latent atrial fibrillation in up to about 5% of cases. Despite the fact that today there are many ways to record heart rate, there is no precise algorithm that allows to detect atrial fibrillation in patients who have survived ischemic stroke of unknown etiology.

B-po03-002 the critical role the allied health professional plays in the management of implantable loop recorder data in patients with history of cryptogenic stroke and atrial fibrillation
Implantation of implantable loop recorders (ILR ’s) requires a dedicated team to manage incoming data. Allied health professionals (AHP) are critical to the management of the numerous events and alerts associated with ILR data. Patients who receive an ILR for the diagnosis of cryptogenic stroke need detailed analysis of each episode to accurate ly identify episodes of atrial fibrillation (AF). Patients who are found to have appropriate detection of AF need to be risk stratified for timely anticoagulation initiation.

B-po01-061 stroke prevention in atrial fibrillation using a percutaneous carotid coil filter: two-year outcomes of the first-in-human capture trial
We previously reported results of a first in human clinical trial (CAPTURE; NCT03571789) in which we studied a novel permanent carotid coil filter that is placed by direct transcutaneous puncture bilaterally into the common carotid arteries (CCAs) to prevent embolic stroke.

B-po01-028 utilization of cardiac monitoring for atrial fibrillation in cryptogenic stroke patients
Atrial fibrillation (AF) is found in ∼1/3 of cryptogenic stroke (CS) patients after long-term monitoring with an insertable cardiac monitor (ICM), enabling the use of anticoagulants for recurrent stroke prevention. However, little is known about monitoring pathways prior to ICM in this population.
