Refining Residual Ischemic Stroke Risk in Anticoagulated Atrial Fibrillation Using Index Outpatient LA Diameter: The CHA2DS2‐VALa Score

Journal of Cardiovascular Electrophysiology, EarlyView.
In anticoagulated atrial fibrillation, residual ischemic stroke risk persists despite guideline‐directed therapy. In this single‐center cohort, an enlarged index outpatient left atrial diameter independently predicted stroke and improved risk stratification when added to CHA2DS2‐VA (CHA2DS2‐VALa), supporting a simple, clinically implementable ...

The V6R/V4R Index: A Novel ECG Parameter for Identifying Idiopathic Ventricular Arrhythmias Originating From the Aortic Cusp

Journal of Cardiovascular Electrophysiology, EarlyView.
The V6R/V4R amplitude index is a novel and practical electrocardiographic parameter for identifying idiopathic ventricular arrhythmias originating from the aortic cusp. A cutoff >0.55 accurately distinguishes cusp from adjacent non‐cusp origins within the left ventricular outflow tract, facilitating targeted mapping and procedural planning.

Dynamic Behavior of Left Atrial Low‐Voltage Areas in Persistent Atrial Fibrillation: Implications for Substrate‐Guided Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Patient selection and analysis flow diagram. The exact pre‐inclusion denominator and reliable reason‐specific exclusion counts could not be reconstructed because a prospectively maintained screening log was unavailable. The diagram summarizes the final study cohort and analysis‐specific sample sizes. AF, atrial fibrillation; LVA, low‐voltage area; SR1,

Large Language Model‐Based Localization of Premature Ventricular Contraction Origins: A Retrospective Diagnostic Accuracy Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Accurate localization of premature ventricular contraction (PVC) origin from 12‐lead electrocardiography (ECG) is important for procedural planning in catheter ablation. Although convolutional neural network (CNN)‐based models have shown promising diagnostic performance, they require task‐specific training and remain limited in ...
