Clinical Utility of Tissue Proximity Indication With a Variable‐Loop Circular Catheter for Pulmonary Vein Isolation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The variable‐loop circular catheter (VLCC, VARIPULSE) is a pulsed‐field ablation (PFA) catheter equipped with a Tissue Proximity Indication (TPI) function, which monitors catheter‐tissue contact. Although TPI‐negative sites have been reported to contribute to gap formation, no studies have evaluated the utility of real‐time function.

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 ...

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 ...
