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-03-048 clinical utility of implantable loop recorders after cryptogenic stroke: insights from a large academic stroke center
Detection of occult AF using implantable loop recorders (ILR) has become routine practice in the evaluation of cryptogenic stroke, yet there are few data demonstrating that ILRs reduce risk of recurrent stroke.

Po-04-216 patient enabled inr optimization : a multicenter prospective study
For patients using Vitamin K antagonists (VKA), maximizing time within the therapeutic range (TTR) reduces stroke, major hemorrhage, and death. Despite improvements in counselling and patient education, patients using Vitamin K antagonists have a poor TTR.

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-03-177 implementation of a multidisciplinary, evidence-based algorithm for management of embolic stroke of undetermined source: a single center experience
Embolic stroke of undetermined source (ESUS) is a poorly understood stroke subtype. The recent secondary stroke prevention guidelines provide new clarity properly defining, evaluating, and treating this subtype. In particular, appropriate selection of patients requiring additional evaluation by TEE or extended cardiac rhythm monitoring via implantable loop recorder (ILR) was emphasized to improve diagnostic yield and resource utilization.

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-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-03-196 long-term clinical outcomes of peri-device leak in patients undergoing left atrial appendage occlusion in the amulet ide trial
The Amulet IDE trial is a global, randomized (1:1) trial of the Amplatzer ™ Amulet™ LAA occluder (Abbott) versus the Watchman™ device (Boston Scientific) in patients with non-valvular AF. Patients with a peri-device leak (PDL)> 3mm have shown to be at increased risk for stroke or systemic embolism (SSE) at 18 months. However, longer-term clinical implications from PDL are unclear.

Po-04-025 a perfect storm - refractory torsades in a patient with mitochondrial disease and severe hypothyroidism
Mitochondrial diseases (MD) such as Mitochondrial Encephalopathy, Lactic acidosis, And Stroke-like episodes (MELAS), Myoclonic Epilepsy with Ragged Red Fibers syndrome (MERRF) and Leber ’s hereditary optic neuropathy are associated with ventricular pre-excitation and WPW. Refractory Torsades de Pointes (TdP) as a complication of MD or hypothyroidism is very rare

Po-05-141 association of interatrial block and the development of atrial fibrillation among patients with hypertrophic cardiomyopathy
Atrial fibrillation (AF) is the most common sustained arrhythmia among those with hypertrophic cardiomyopathy (HCM), affecting 1 in 5 patients. The combination of HCM and AF is associated with an increased risk of stroke, heart failure, and mortality. Interatrial block (IAB) is a distinct electrocardiographic (ECG) pattern describing conduction delay between the right and left atria through Bachmann ’s bundle. IAB has been identified as a predictor of AF across several disease states including congestive heart failure, valvular disease, and cardiac amyloidosis.

Po-05-136 in stroke patients, do baseline electrocardiogram findings correlate with diagnostic findings on long-term monitoring with implantable loop recorder?
In patients with cryptogenic stroke, long-term monitoring is standard-of-care to exclude atrial tachyarrhythmias. Prior studies have not examined interatrial block (IAB) and other ECG markers paired with long-term continuous monitoring (the current gold standard) to predict likelihood of atrial fibrillation (AF) detection in stroke patients.
