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,

Ventricular Tachycardia Ablation in Structural Heart Disease With LVEF > 35%: Clinical Outcomes and Recurrence Patterns

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background In patients with structural heart disease (SHD) and moderately impaired left ventricular ejection fraction (LVEF > 35%), data on outcomes after ventricular tachycardia (VT) ablation remain limited. This analysis focuses on VT recurrence after ablation in patients presenting with sustained VT and LVEF > 35% within a secondary ...

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 ...

Terminal S Wave Pattern in Lead V3 as a Simple Marker for Ventricular Tachycardia Risk Stratification in Patients With Repaired Tetralogy of Fallot

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Patients with repaired tetralogy of Fallot (rTOF) remain at risk of ventricular tachycardia (VT). This risk is most commonly related to slow conduction within the septal isthmus, which is defined as the region between the ventricular septal defect (VSD) patch and adjacent valvular annuli.

Catecholaminergic polymorphic ventricular tachycardia

, 2008
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a highly malignant form of arrhythmogenic disorder characterized by exercise- or emotional-induced polymorphic ventricular tachycardia in the absence of detectable structural heart disease ...

Time‐Dependent Diagnostic Yield and Therapeutic Impact of Implantable Loop Recorders, Brugada Syndrome as the Exception

Journal of Cardiovascular Electrophysiology, EarlyView.
Diagnostic yield and therapeutic impact varied substantially according to the indication for implantation. Actionable diagnoses were concentrated in the early follow‐up period for syncope and palpitations, whereas late atrial fibrillation detection after cryptogenic stroke could still modify antithrombotic management. In contrast, patients with Brugada

Brugada Syndrome in the Pediatric Population: Diagnostic Challenges and Clinical Outcome—Results of the German Multicenter Study COGIA

Journal of Cardiovascular Electrophysiology, EarlyView.
The study examines 76 patients of the German multicenter study COGIA with suspected BrS in 12 centers in Germany. Thirty‐nine patients met the current ESC diagnostic criteria, 34 of whom met the Shanghai Score criteria. Four major arrhythmic events (ACA, SCD, appropriate ICD shock) occurred in the cohort (5.3%), all in the group of patients fulfilling ...

Characteristics of Atrial Tachycardia Recurrence After Pulsed Field Ablation: Insights From Repeat Ablation Procedures

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulmonary vein isolation (PVI) using pulsed field ablation (PFA) for atrial fibrillation (AF) is becoming increasingly widespread. However, characteristics of atrial tachycardia (AT) recurrence after PFA remain unclear. We aimed to investigate characteristics of AT recurrence in comparison with AF recurrence after PFA‐based PVI ...

Clinical Outcomes After Catheter Ablation in Patients With Structural Heart Disease and Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction In patients with ischemic cardiomyopathy (ICM), recurrent VF may be treated with catheter ablation by targeting triggering premature ventricular complexes (PVCs) and/or ventricular scar homogenization. Data on optimal ablation strategies in patients with non‐ischemic cardiomyopathy (NICM) remain limited.
