A rare case of an unexpected trigger of paroxysmal atrial fibrillation in the right atrial appendage diverticulum

BMC Cardiovascular Disorders
Introduction We described a rare case of an adolescent girl with paroxysmal atrial fibrillation originating from the right atrial appendage diverticulum and successfully converted to sinus rhythm after surgical intervention.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Predictors and Outcomes of 30‐Day Readmissions Following Electrical Cardioversion for Atrial Fibrillation: Insights From the Nationwide Readmissions Database

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Among 134 114 atrial fibrillation hospitalizations treated with electrical cardioversion in the 2016–2017 NRD, 9.9% resulted in 30‐day readmission. Readmission was associated with higher mortality, longer stay and greater costs. Predictors included cardiometabolic comorbidities, female sex, lower income, Medicare/Medicaid insurance, nonhome discharge ...

Documented Obstructive Sleep Apnea, Cardiometabolic Phenotype, and Rhythm‐Related Outcomes After Atrial Fibrillation Ablation: An Observational Cohort Study

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Documented OSAS identified a higher‐risk cardiometabolic phenotype in patients undergoing AF ablation, including greater obesity, hypertension, diabetes, persistent AF, and adverse lipid markers. However, it did not independently predict post‐ablation rhythm‐related outcomes in either the registry cohort or the actively followed cohort.

Radiation dose optimization in coronary CT angiography clinical application of absolute phase gating in patients with atrial fibrillation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Atrial fibrillation (AF) poses significant challenges for coronary CT angiography (CCTA) due to R‐R interval variability, often necessitating high radiation dose protocols. Absolute phase gating, which uses fixed millisecond delays rather than percentage‐based cardiac cycle timing, may optimize image quality while reducing radiation

Safety and Effectiveness of Sutimlimab in Cold Agglutinin Disease: A Real‐World International Experience

American Journal of Hematology, Volume 101, Issue 7, Page 1597-1604, July 2026.
ABSTRACT Sutimlimab is a monoclonal antibody against complement fraction C1s approved for the treatment of hemolytic anemia due to cold agglutinin disease (CAD). Here, we analyzed and report the largest international CAD cohort of sutimlimab‐treated patients ever reported to highlight its safety and effectiveness in the real‐world setting. We accrued a
