Po-03-061 utility of implantable loop recorders for cryptogenic strokes to detect arrhythmias other than atrial fibrillation
Implantable loop recorders (ILR) are recommended to detect atrial fibrillation (AF) in cases of cryptogenic stroke (CS). However, the utilization of loop recorders for the diagnosis of other arrhythmias in patients with a history of cryptogenic stroke is limited.

Po-02-093 impact of ablation outcome on cognitive function in patients with atrial fibrillation
Emerging evidences suggest increased risk of all forms of dementia in patients with atrial fibrillation (AF) even in the absence of overt stroke. Cerebral hypoperfusion and the risk of cerebrovascular micro- and macro-embolism are plausible explanations for the predisposition for cognitive decline in AF.

Po-04-214 video-based facial detection of atrial fibrillation across human complexions
It has been posited that the Black vs. White disparity in stroke risk may be partly attributable to the relative underdetection of AF in Black compared with White patients. We propose a novel monitoring solution that could minimize the impact of the socio-economic disparities in access to remote monitoring solutions. We developed a video-based monitoring technology to detect AF without the need for a patient to adopt a dedicated wearable device. It is a low-cost software-only solution running on smartphones.

Po-04-151 a new sequential artificial intelligence algorithm for predicting atrial fibrillation using serial 12-lead electrocardiograms
Because the early stage of atrial fibrillation (AF) is difficult to detect, a significant number of patients are exposed to the risk of stroke without forewarning. Artificial intelligence (AI) algorithms using 12-lead electrocardiograms (ECGs) are being developed to detect AF early.

Po-04-144 impact of age on atrial arrhythmia outcomes after percutaneous asd closure
Atrial Septal Defects (ASD) are one of the most common congenital heart defects, and if unrepaired, increase the risk of atrial fibrillation (AF) and atrial flutter (AFL). AF/AFL are linked to an increased risk of stroke and heart failure yet, it is not clear from existing data whether percutaneous ASD closure reduces the overall burden of AF/AFL and whether AF/AFL prevalence is impacted by closure age.

Po-03-005 best anticoagulation strategy for stroke prophylaxis in atrial fibrillation patients with amyloidosis
A considerable proportion of elderly patients are known to have coexistent atrial fibrillation (AF) and amyloidosis. Both conditions increase stroke risk.

Po-03-175 cost-effectiveness of transesophageal echocardiogram prior to atrial fibrillation ablation.
With universal adoption of uninterrupted anticoagulation (AC) it is suggested that transesophageal echo (TEE) screening for LA (left atrial) thrombus prior to AF ablation procedure could be omitted. Observational studies suggest that post-procedure stroke might not be completely prevented by TEE. Accumulating data on safety of AF ablation on uninterrupted AC together with a risk of TEE complications raise the question of indications for TEE in all AF ablation patients.

Po-03-153 post-operative atrial fibrillation standarization of care through clinical care pathways for cardiac surgical patients
Post-operative atrial fibrillation (POAF) occurs commonly in cardiac surgical patients up to 55% of the time leading to an increase risk of thromboembolic events, stroke, renal and respiratory failure, and an increase in all-cause 30-day and 6-month mortality.

Po-01-071 risk of stroke in patients with atrial fibrillation undergoing catheter ablation compared to medical therapy: a meta-analysis of randomized controlled trials
Atrial fibrillation (AF) is a major risk factor for stroke. Although catheter ablation is associated with higher chance of sinus rhythm maintenance compared to medical therapy, the extent to which successful catheter ablation reduces stroke risk remains unclear.

Po-04-057 atrial fibrillation cured by pacemaker reprogramming
Atrial fibrillation (AF) is commonly detected by remote monitoring of implanted devices. A common question is whether to start anticoagulation in patients with detected AF at risk of stroke. However, the cause of AF is rarely able to be diagnosed or corrected. Repetitive non-reentrant ventriculoatrial synchrony (RNRVAS) is a pacemaker mediated arrhythmia that can occur in patients with intact ventriculoatrial (VA) conduction. Ventricular pacing with retrograde atrial activation that falls within the PVARP is followed by atrial pacing, often delivered while the atrium is refractory.

Po-01-002 association of novel combined genetic polymorphisms with risk of thromboembolism in patients with atrial fibrillation
AF patients remain on oral anticoagulation (OAC) or left atrial appendage (LAA) closure is performed for thromboprophylaxis. However, clots on the closure device as well as stroke/transient ischemic attack (TIA) are observed to occur in some patients despite of being on blood thinners or after being off-OAC for a very brief period.

Po-03-190 safety and outcomes of left atrial appendage occlusion in nonagenarians
As the human lifespan continues to lengthen, so too will the incidence of atrial fibrillation and the need for anticoagulation for stroke prevention. However, many of these patients that require anticoagulation are also at high risk of bleeding making left atrial appendage occlusion (LAAO) an attractive option. Studies on the procedural risks in the very elderly are limited and the safety of LAAO in nonagenarians is lacking.

Po-03-164 feasibility of gadolinium contrast fluoroscopy to facilitate watchman flx implantation using intracardiac echocardiography
In patients with non-valvular atrial fibrillation, left atrial appendage closure (LAAC) is an alternative to oral anticoagulation for stroke-risk reduction. The standard imaging used during LAAC procedures is transesophageal echocardiography with iodinated contrast media. The recent worldwide supply chain shortage in April 2022 resulted in a global shortage of these contrast agents, limiting the ability to perform LAAC.

Po-03-135 left atrial appendage occlusion versus standard of care in patients with atrial fibrillation and a prior thrombo-embolic event despite oral anticoagulant therapy: a propensity score matched comparison
Patients with atrial fibrillation (AF) that suffer from ischemic stroke despite oral anticoagulant (OAC) therapy have a very high risk of recurrent stroke and better prevention strategies are needed. Left atrial appendage occlusion (LAAO) is a promising secondary prevention strategy that may provide mechanical protection. However, evidence showing effectiveness of LAAO in this population is scarce and the current international guidelines only consider LAAO in patients with a contra-indication for OAC.

Po-03-133 both overuse and underuse of oral anticoagulation post-atrial fibrillation ablation in a large healthcare system
Guidelines recommend that decisions regarding oral anticoagulation (OAC) post ablation for atrial fibrillation (AF) should be based solely on the patient ’s stroke risk profile, regardless of the outcomes of the procedure. The adherence to this recommendation in clinical practice has not been examined.
