Comparison of Two Pulsed Field Ablation Systems for Atrial Fibrillation: One‐Year Outcomes From a Multicenter Registry

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background While various pulsed field ablation (PFA) systems for atrial fibrillation (AF) ablation have become available in recent years, data comparing long‐term efficacy outcomes remain limited. Purpose To compare long‐term efficacy outcomes of two commercially available PFA systems to perform pulmonary vein isolation (PVI) for AF in a ...

An Approach to Working Up Cases of Embolic Stroke of Undetermined Source

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundFrom a therapeutic viewpoint, it is important to differentiate the underlying causes of embolism in patients with cryptogenic stroke, such as aortic arch atheroma, patent foramen ovale, and paroxysmal atrial fibrillation.

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.

Implementation of a Standardized Nurse‐Guided Heparinization Protocol Improves Anticoagulation During Left Atrial Ablation Procedures

Journal of Cardiovascular Electrophysiology, EarlyView.
A standardized, nurse‐led heparinization protocol significantly improves the speed, consistency, and precision of achieving therapeutic ACT levels during left atrial ablation, while reducing excessive anticoagulation and maintaining a comparable safety profile to conventional operator‐guided dosing.

Association Between Contact Force and Acute Lesion Effectiveness in Focal Pulsed Field Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Pulsed field ablation (PFA), based on irreversible electroporation, is a non‐thermal modality designed to create myocardial lesions while minimizing collateral injury. The determinants of acute lesion effectiveness in humans remain incompletely understood.

Patient‐Reported Outcome Measures Following Pulsed‐Field Ablation Versus Thermal Ablation of Atrial Fibrillation: The PROMs‐PFA Study

Journal of Cardiovascular Electrophysiology, EarlyView.
Pulsed‐field was associated with less early post‐procedural chest pain than thermal ablation. ABSTRACT Background Pulsed‐field ablation (PFA) has transformed atrial fibrillation (AF) ablation, but how the early patient experience compares with thermal techniques remains unclear.

Comparative Efficacy of Continuous Versus Patch ECG Monitoring in Detecting Atrial Fibrillation Recurrence Post Catheter Ablation: Insights From the REAL‐AF Registry

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Effective monitoring of atrial fibrillation (AF) recurrence following catheter ablation is crucial for optimizing patient outcomes. Various monitoring strategies exist, but effectiveness comparisons remain underexplored. Objective This study compares the recurrence of atrial arrhythmias detected by continuous versus patch ECG ...

Comparison of Spatio‐Temporal Dispersion Electrogram Ablation and Low Voltage Zone Ablation in Patients With Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
This study compared STDE‐guided versus LVZ‐guided ablation beyond PVI in 107 persistent AF patients. At 24 months, the AF‐free survival rate was significantly higher in the STDE group (76.3% vs. 58.4%, p=0.027). STDE ablation independently reduced recurrence risk (HR: 0.29, p=0.004), providing superior clinical efficacy over LVZ ablation.

Impact of Carina Width on Re‐Ablation Rate of Atrial Fibrillation After Primary Cryoballoon‐Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Right side carina width is associated with the incidence of reconnection of RPVs and re‐ablation. Increased left side carina width was associated with re‐ablation rate, but there was no association with reconnection of the LPVs. ABSTRACT Background Reconnection of the pulmonary veins (PVs) is the primary cause of atrial fibrillation (AF) episodes after

Enhanced Risk Stratification of Atrial Fibrillation Detected After Ischemic Stroke and TIA: The Role of Apnoea–Hypopnoea Index and Hypoxic Burden—A Study From the Bern Sleep‐Stroke Registry

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep‐disordered breathing is an independent risk factor for stroke and atrial fibrillation. Accurate assessment of atrial fibrillation in stroke patients with sleep‐disordered breathing is crucial for secondary prevention. This study aimed to determine whether combining apnoea–hypopnoea index and hypoxic burden improves risk stratification ...
