Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Electrogram peak‐to‐peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography–derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained with omnipolar, bipolar, and unipolar mapping.

Feasibility, Safety, and Efficacy of Pulsed Field Ablation for Ventricular Arrhythmias: Insights From a Large Health System Registry in the United States

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is an emerging non‐thermal ablation modality with proven safety in atrial arrhythmia ablation. However, data on its performance for ventricular arrhythmias (VA) remain limited. Objective To evaluate the feasibility, safety, and efficacy of PFA for complex VA in a multicenter real‐world US registry ...

Learning Curve of Pentaspline Pulsed‐Field Ablation With Posterior Wall Isolation for Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pentaspline pulsed‐field ablation (PFA) has emerged as a novel modality for pulmonary vein isolation (PVI) and posterior wall isolation (PWI) in persistent atrial fibrillation (AF). However, the learning curve associated with combined PVI + PWI and the contribution of anatomical factors to acute lesion completeness remain ...

Impact of Ganglionated Plexus Ablation on Early Recurrence After Thoracoscopic Atrial Fibrillation Ablation: A Post Hoc Analysis of the AFACT Study

Journal of Cardiovascular Electrophysiology, EarlyView.
Adjunctive ganglionated plexus (GP) ablation did not reduce early AF recurrence after thoracoscopic AF ablation but was associated with a later first recurrence. In the GP‐ablation group, early recurrence was associated with late recurrence; this exploratory finding is compatible with, but does not establish, a greater contribution of pre‐existing ...

Pulmonary Vein Isolation Alone Versus Adjunctive Ablation for Paroxysmal Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
Clinical Outcomes of Pulmonary Vein Isolation Alone Versus Additional Lesion Sets in Paroxysmal Atrial Fibrillation ABSTRACT Background Pulmonary vein isolation (PVI) is the standard ablation strategy for paroxysmal atrial fibrillation (PAF). Despite guideline recommendations favoring PVI alone in PAF, some operators routinely perform extra pulmonary ...

Evolving Mechanisms on Mortality in Atrial Fibrillation: A 25‐Year National Death‐Certificate Analysis

Journal of Cardiovascular Electrophysiology, EarlyView.
This 25‐year national analysis reveals a major shift in atrial fibrillation‐related mortality, driven by rapidly rising rates of heart failure and stroke‐free dementia. These trends underscore the urgent need to expand management beyond traditional stroke prevention to prioritize comprehensive heart failure care and cognitive health.
