Article Abstract

As the most frequently diagnosed arrhythmia, atrial fibrillation (AF) has been recently reported to be closely related to ryanodine receptor (RyR2) dysfunction and calcium leak. Here, using non-integrating sendai viral method, we generated one iPSC line from peripheral blood mononuclear cells (PBMC) isolated a 10-year-old boy with simple atrial fibrillation which carries the heterozygous mutation in RYR2 gene (c.14638G > A, p.V4880I). The generated iPSC line was identified by the typical cell morphology, highly expressed pluripotent markers, normal karyotype, and in-vitro trilineage differentiation potential. It will provide a useful model for studying the pathophysiological consequences of RYR2 mutation on the AF pathogenesis.

How Often is Multifocal Atrial Tachycardia Mistaken for Atrial Fibrillation in the Emergency Department?

Am J Med Sci

September 2025

The Ruth and Bruce Rappaport Faculty of Medicine, Technion, Israel Institute of Technology, Haifa, Israel; Department of Internal Medicine, Lady Davis Carmel Medical Center, Haifa, Israel.

Objective: Multifocal atrial tachycardia (MAT), characterized by an irregularly irregular rhythm, is often regarded as a clinical imitator of atrial fibrillation (AF). We aimed to evaluate the prevalence of MAT misclassification as AF in the emergency department (ED) setting.

Methods: A retrospective analysis of 1,828 ECGs from patients discharged with AF diagnoses over five years.

Background: Fine particulate matter (PM) has been previously linked to cardiovascular diseases (CVDs). PM is a mixture of components, each of which has its own toxicity profile which are not yet well understood. This study explores the relationship between long-term exposure to PM components and hospital admissions with CVDs in the Medicare population.

Background: Final infarct volume (FIV) is a strong predictor of stroke outcomes. Although smaller FIV are associated with better outcomes, many patients fail to achieve functional independence. We aimed to identify poor outcome predictors in patients with anterior large vessel occlusion stroke (LVOS) who underwent mechanical thrombectomy (MT) and had small FIV.

Artificial Intelligence Automation of Echocardiographic Measurements.

Background: Accurate measurement of echocardiographic parameters is crucial for the diagnosis of cardiovascular disease and tracking of change over time; however, manual assessment requires time-consuming effort and can be imprecise. Artificial intelligence has the potential to reduce clinician burden by automating the time-intensive task of comprehensive measurement of echocardiographic parameters.

Objectives: The purpose of this study was to develop and validate open-sourced deep learning semantic segmentation models for the automated measurement of 18 anatomic and Doppler measurements in echocardiography.
