Impact of Left Bundle Branch Area Pacing on Echocardiographic Parameters and Symptoms: Data From the Conduction System Pacing Italian Network Group (C‐SING) Study

Journal of Cardiovascular Electrophysiology, EarlyView.
Left bundle branch area pacing is associated with preservation of ventricular function in patients with bradycardia indications and with significant reverse remodeling and symptomatic improvement in patients with heart failure. Maintaining a high percentage of effective LBBAP capture is critical to minimize the risk of pacing‐induced cardiomyopathy and

Prospective Trial of Radiofrequency Catheter Ablation of High Dominant Frequencies After Pulmonary Vein Isolation in Non‐Paroxysmal Atrial Fibrillation (PAD‐AF Trial): A Multicenter, Randomized Clinical Trial

Journal of Cardiovascular Electrophysiology, EarlyView.
In persistent AF, adjunctive dominant frequency‐guided ablation after pulmonary vein isolation did not significantly improve outcomes. Limited overlap between high‐frequency sites and low‐voltage areas suggests functional–structural dissociation, while right atrial low‐voltage burden predicts recurrence.

Prevalence and prognosis of patients with lone and paroxysmal atrial tachyarrhythmias showing Brugada-type electrocardiograms after class IC antiarrhythmic drug administration but no risk-stratifying factors

Journal of Arrhythmia, 2013
Background: Class IC antiarrhythmic drugs, used to prevent paroxysmal atrial tachyarrhythmias (ATs), are well known to effectively unmask the electrocardiogram (ECG) pattern of Brugada syndrome.

Mechanical Circulatory Support During Ventricular Tachycardia Ablation: A Systematic Review and Meta‐Analysis of Procedural and Clinical Outcomes

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Catheter ablation is an established therapy for ventricular tachycardia (VT); however, hemodynamic instability frequently limits procedural mapping and success. Temporary mechanical circulatory support (tMCS) devices are increasingly used to maintain end‐organ perfusion during VT ablation, yet their impact on clinical outcomes remains ...
