Summary: Atrial fibrillation (AF) is a major cardiac arrhythmia associated with higher risk of cardiovascular morbidity and mortality. Rate control is one of the strategies for managing AF, aiming to improve symptoms and quality of life, although its effectiveness in preventing disease progression and reducing symptoms in highly symptomatic patients is limited. Despite being widely used, there are still debates regarding the use of rate control as first line management for all patients with AF.

Summary: Ablation strategies are still unclear for persistent atrial fibrillation patients who experience recurrence despite intact pulmonary vein isolation. Advanced mapping techniques that can identify extra-pulmonary vein sources of atrial fibrillation are increasingly necessary as the ability to perform durable pulmonary vein isolation improves. Electrographic flow mapping provides a novel method for mapping atrial fibrillation by reconstructing organized wavefront propagation within chaotic electrical conduction. This paper explains the technical and mathematical foundations of electrographic flow mapping and demonstrates its clinical applications.

Summary: This study compared the efficacy of electrographic flow (EGF) guided ablation with empiric ablation in the treatment of persistent atrial fibrillation. The results showed that EGF-guided ablation led to fewer AF recurrences at 12 months. Despite longer procedure times, it was safe and offered a more targeted, patient-specific ablation strategy for this complex group of patients.

Summary: This study identified the causative genetic variation related to atrial fibrillation (AF) at the ZFHX3 locus and explored the impact of Zfhx3 loss on cardiac function in mice. The results showed that ZFHX3 is the causative gene for AF at the 16q22 locus and its loss leads to cardiac abnormalities and dysregulation of atrial-specific pathways involved in AF susceptibility.

Summary: This case-control study compared atrial conduction velocity (CV) in patients with and without atrial fibrillation (AF). The study found no significant difference in biatrial CV between the two groups, except for a reduction in CV in the Bachmann's bundle (BB) area in the AF group. AF was associated with prolonged total activation times and decreased voltages at BB, indicating a potential role of BB in AF development and maintenance.

Summary: The study validated multiple risk models and scores for predicting atrial fibrillation (AF) risk in young individuals. The results showed that multivariable models had limited additional discriminatory value over age alone, suggesting that the selection strategy for primary AF screening should not be expanded to younger individuals.

Summary: Atrial fibrillation (AF) is the most common arrhythmia worldwide and is associated with increased morbidity and mortality. The post-translational modification of proteins, especially protein phosphorylation, may explain how risk factors lead to AF. Mass spectrometry (MS) is a common and highly resolute technique for studying protein phosphorylation, and future research utilizing MS technology aims to better understand the role of phosphorylation in the pathophysiology of AF.

Summary: Atrial fibrillation (AF) is a common cardiac arrhythmia with a high prevalence worldwide. It is associated with an increased risk of death, stroke, and peripheral embolism. Despite genetic studies identifying AF-associated genes, their definitive impact is not yet established. This review discusses recent advances in understanding and managing AF, including epidemiology, genetics, pathophysiology, and potential treatment options.

Summary: Atrial fibrillation patients often experience disease-specific fears that are not routinely addressed in clinical management. Borrowing from recurrence fear models in cancer research, a patient-centric approach to disease intervention may improve outcomes for atrial fibrillation patients.

Summary: Atrial myopathy may contribute to the progression of atrial fibrillation and affect the success of ablation. DEEP mapping can identify areas prone to re-entry initiation and is more common in persistent AF patients compared to paroxysmal AF patients.

Summary: Both long-term and short-term alcohol consumption can disrupt internal homeostasis and contribute to the development of atrial fibrillation. This study examines the involvement of ferroptosis, an iron-dependent form of cell death, in alcohol-induced atrial fibrillation. The results show that frequent excessive alcohol consumption activates ferroptosis and increases susceptibility to atrial fibrillation. However, inhibition of ferroptosis can reduce iron overload and reactive oxygen species generation, ultimately decreasing the susceptibility to atrial fibrillation.

Summary: This study aims to determine whether there are pathophysiological signatures associated with the clinical spectrum of atrial tachyarrhythmias. The results show that the size of spatial regions showing repetitive synchronized electrogram shapes decreases from patients with atrial tachycardia to atrial fibrillation patients who respond to ablation, to atrial fibrillation patients without acute response. These findings provide a platform for comparing mapping tools and mechanisms among different atrial fibrillation patient groups.

Summary: It has been found that a deep convolutional neural network can accurately predict long term cardiovascular risk based on resting electrocardiogram (ECG) information. The developed Stanford Estimator of Electrocardiogram Risk (SEER) demonstrates high predictive accuracy when evaluated independently at different medical centers. SEER, when used alongside other risk tools, has the potential to greatly improve cardiovascular risk stratification and aid in medical decision making.

Summary: This study compared the arrhythmia burden in patients receiving ibrutinib, non-BTK TKIs, or non-TKI therapies. The results showed that patients receiving ibrutinib had a higher prevalence of atrial fibrillation and non-sustained ventricular tachycardia, and a higher rate of treatment interruption due to arrhythmias.
