Po-625-05 electrocardiographic deep terminal negative of the p wave in v1 and ischemic stroke:the atherosclerosis risk in communities (aric) study
Abnormal P-wave indices are associated with ischemic stroke independent of atrial fibrillation (AF). Deep terminal negative of the P wave in V1 (DTNPV1) is a simple ECG index that reflects underlying left atrial remodeling. However, it is unknown whether DTNPV1 is associated with ischemic stroke.

Po-701-04 outcomes of left atrial appendage closure in patients with atrial fibrillation and end-stage renal disease on dialysis
Oral anticoagulation (OAC) therapy is the mainstay of treatment for stroke-risk reduction in patients with atrial fibrillation (AF). However, OAC use in patients with end-stage renal disease (ESRD) on dialysis is associated with a significantly increased risk of bleeding and an uncertain benefit in stroke reduction. In these patients, left atrial appendage closure (LAAC) could be alternative.

Po-701-01 nine month readmission rates and clinical outcomes of anticoagulation versus watchman device in octogenarians
Atrial Fibrillation (AF), the most common arrhythmia in older adults, is fraught with an increased risk of stroke. Studies which have demonstrated non-inferiority of Left atrial appendage occlusion (LAAO) with a watchman device compared to oral anticoagulation for stroke risk reduction in AF did not include patients greater than 80 years of age, making it difficult to generalize these results to this population.

Po-699-03 ischemic stroke risk correlates with degree of left atrial fibrosis in atrial fibrillation patients
Increasing data support a causal relationship between left atrial (LA) remodeling and ischemic stroke (IS) risk in atrial fibrillation (AF) patients.

Po-697-02 impact of left atrial appendage stump on arrhythmogenicity and stroke risk after atri-clip in patients with persistent atrial fibrillation
Surgical left atrial appendage occlusion (LAAO) with an atrial clip (Atricure) is frequently performed for stroke prophylaxis in patients with atrial fibrillation (AF). Scant data exist for arrhythmogenicity and thromboembolic risk with the residual LAA stump.

Po-639-04 watchman vs amulet left atrial appendage occluder for stroke prophylaxis
Left atrial appendage Occlusion (LAAO) is an alternative to oral anticoagulation to reduce stroke risk in patients with non-valvular atrial fibrillation (NVAF).

Po-639-03 3d mapping facilitated, intra-cardiac echocardiography (ice) guided left atrial appendage occlusion (laao) is feasible and safe, providing similar efficacy with less personnel than transesophageal echocardiography (tee) guided procedures
Left atrial appendage occlusion (LAAO) provides an alternative for stroke prevention in patients with atrial fibrillation who cannot be safely anticoagulated long-term. WATCHMAN FLX placement was described, and is traditionally performed, with transesophageal echocardiography (TEE) guidance under general anesthesia (GA). The implanting physician, echocardiography team, and anesthesia team must all be present, complicating coordination and scheduling. The use of intracardiac echocardiography (ICE) with 3D mapping guidance in place of TEE for LAAO procedures can eliminate the need for additional personnel.

Bs-400-31 association between sleep apnea, atrial fibrillation and incident stroke in a very large population of young individuals
Sleep apnea (SA) worsens outcomes in patients with atrial fibrillation/flutter (AF), and both are common in young patients (20-50 years). However, it is unreported what proportion of young patients with SA have or will develop AF or stroke.

Po-718-05 prescribing patterns of direct anticoagulants versus vitamin k antagonists in patients with non-valvular atrial fibrillation and extreme obesity
Anticoagulation is an effective treatment in prevention of stroke in patients with atrial fibrillation (AF). Direct anticoagulants (DOACs) have been favored over vitamin K dependent antagonists (VKAs) given their safety and efficacy. However, there is limited real-world data on DOAC use among patients with extreme obesity.

Po-718-03 identifying and characterizing patients with atrial fibrillation and elevated thromboembolic risk who are not appropriately anticoagulated
Atrial fibrillation (AF) is the leading cause of stroke, which can be reduced by 70% with appropriate use of anticoagulation therapy. Nationally, appropriate anticoagulation rates for patients with AF with elevated thromboembolic risk are as low as 50% even across the highest CHADS2VASC score cohorts. Understanding anticoagulation fallout rates among gender, ethnicity, and socioeconomic status is an important first step towards decreasing the risk of thromboembolic events.

Po-716-08 real world clinical outcomes of left atrial appendage occlusion device in the octogenarian and nonagenarian patients
Few trials evaluated real world clinical outcomes in patients with atrial fibrillation receiving the Watchman device for left atrial appendage closure. In the recent Ewolution trial, mean age of patients was 73.4 + 8 years. Although few patients> 80 years were included, the safety and efficacy in terms of clinical outcomes of stroke, bleeding and mortality in the octogenarian and nonagenarian population specifically has not been reported in real world setting.

Po-716-07 is cha2ds2vasc score useful for predicting the risk of stroke in patients with atrial fibrillation and cancer? : a single-center observational analysis
Patients with active cancer were historically excluded from clinical trials validating the CHA2DS2VASc score for stroke prediction in atrial fibrillation (AF). Limited data have questioned the predictive value of the score in patients with cancer and AF, underscoring the need for more personalized scores for prediction of stroke in these patients.

Po-716-02 short term readmission rates and clinical outcomes of anticoagulation versus watchman device in octogenarians
Atrial Fibrillation (AF) is the most common sustained cardiac arrhythmia with prevalence increasing with age. Left atrial appendage occlusion (LAAO) with watchman device has been found to be noninferior to oral anticoagulation for long-term stroke risk reduction in patients with AF. Patients greater than 80 years of age have been underrepresented in most of these trials making application of findings challenging in this subset of patients.

Po-626-03 preclinical safety of adkcnh2-g628s for post-op af
Post-operative atrial fibrillation (POAF) occurs in 30% of cardiac surgeries, increasing risk of stroke, MI, and death. We propose gene therapy with an adenovirus encoding the G628S mutation of KCNH2 (AdKCNH2-G628S) to prevent POAF. We have reported preclinical efficacy in pigs.
