Long-Term Imaging and Clinical Outcomes of Surgical Left Atrial Appendage Occlusion With AtriClip
Surgical left atrial appendage (LAA) occlusion with an AtriClip (AtriCure, West Chester, Ohio) is frequently performed for stroke prophylaxis in patients with atrial fibrillation (AF). We conducted a retrospective analysis of all patients with long-standing persistent AF who underwent hybrid convergent ablation and LAA clipping. Contrast-enhanced cardiac computed tomography was performed at 3 to 6  months after LAA clipping to assess the degree of complete closure and the residual LAA stump. A total of 78 patients (64 ± 10 years, 72% male) underwent LAA clipping as part of hybrid convergent AF ablation, from 2019 to 2020.

Atrial Cardiopathy: Redefining Stroke Risk Beyond Atrial Fibrillation
Atrial fibrillation (AF) and ischemic stroke are dual epidemics in society, both associated with poor clinical outcomes, patient disability, and significant healthcare expenditure. The conditions are interrelated and share complex causal pathways. Risk stratification algorithms such as the CHADS2 and CHA2DS2-VASc score offer predictive value in stroke and systemic embolism risk in the AF population, however, have limitations. Recent evidence suggests that an intrinsically prothrombotic atrial substrate may precede and promote AF and lead to thromboembolic events independent of the arrhythmia, allowing for a window of inter...

An Explainable Artificial Intelligence Approach for Discovering Social Determinants of Health and Risk Interactions for Stroke in Patients With Atrial Fibrillation
Stroke remains the primary source of morbidity and mortality associated with atrial fibrillation (AF), despite major advances in prevention. Although effective stroke-prevention strategies are available, optimal implementation of these treatments is limited by (1) rudimentary stroke risk stratification tools (i.e., CHADS2-VA2Sc), and (2) disparities in care and outcomes of AF. Over 150,000 yearly strokes in the United States occur in patients with AF.1 Many of these occur in patients with AF who are misclassified as low-risk or fail to receive appropriate therapies because of healthcare disparities.

Sex ‐based differences in safety and efficacy of catheter ablation for atrial fibrillation
ConclusionFemale patients were older and had higher CHA2DS2-VASc scores compared to males at the time of AF ablation. Women tried more AADs than men before ablation. One-year arrhythmia recurrence rates and procedural complications were similar in both sexes. No sex-based differences were observed in safety and efficacy of ablation.

Left Atrial Appendage Occlusion Devices: Are We Isolating the Right Population?
Atrial fibrillation (AF) affects more than 37 million persons worldwide contributing to significant morbidity and mortality.1 Stroke prevention with vitamin K antagonists (VKAs) or non-VKA oral anticoagulants remains the mainstay of therapy in patients with AF because of the reduction of all-cause mortality in randomized clinical trials when compared with placebo. VKAs are necessary for those patients with valvular AF but carry a higher risk of stroke, intracranial hemorrhage, and mortality when compared with non-VKA oral anticoagulants.

Heartbeat: prediction of atrial fibrillation risk
One of the challenges in prevention of stroke is identification of patients at risk of atrial fibrillation (AF) shortly before the onset of the arrhythmia so that prevention therapies can be promptly instituted. In this issue of Heart, Nadarajah and colleagues1 report the development and validation of an algorithm based on data from the UK Clinical Practice Research Datalink GOLD dataset that included 2 081 139 individuals of whom 7386 developed AF within 6 months. This new algorithm-- Future Innovations in Novel Detection of Atrial Fibrillation (FIND-AF) – identified a high-risk cohort with a 20-fold higher 6 month ...

Prescriptive behavior of non-vitamin K oral anticoagulants in patients affected by atrial fibrillation in general practice
Biomed Pharmacother. 2023 Jun 21;165:115020. doi: 10.1016/j.biopha.2023.115020. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common cardiac arrhythmia worldwide and in recent years the pharmacological approach has been strongly implemented; in Italy, the prescription of the non-vitamin K oral anticoagulants (NOAC) was also extended to General Practitioners (GPs) since 2020. The aim of the present study was to investigate the GPs prescribing behaviour of NOACs. An observational study was performed by using the computerized medical record of 14 GPs in Sicily: patients affected by AF were selected and st...

Diagnostic value of carotid intima-media thickness and clinical risk scores in determining etiology of ischemic stroke
CONCLUSIONS: CIMT may help in the diagnosis of stroke etiology. However, compared with vascular risk factors or clinical AF risk scores, CIMT does not provide substantial additional information on the risk of newly detected AF. Thus, stratification of AF risk based on scores, such as the AS5F, is advisable.PMID:37334932 | DOI:10.1177/23969873231182492
