Dominant Frequency Mapping as a Functional Tool for Substrate‐Guided Ventricular Tachycardia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Stimulus‐independent DF mapping integrates intracardiac signals with 3D anatomy to visualize high‐DF activity, with regions derived from SmartTouch and Pentaray catheters showing spatial correspondence with operator‐defined ablation sites. Quantitative analysis demonstrates higher proximity scores at ablation sites, low projection error, and good ...

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.

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 ...

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 ...

A Simplified Epicardial Ablation Strategy for Ventricular Tachycardia Integrating CT‐Derived Epicardial Adipose Tissue Into Three‐Dimensional Electroanatomic Mapping

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Epicardial adipose tissue (EAT) can attenuate electrograms and limit lesion formation during epicardial ventricular tachycardia (VT) ablation. Case Presentation We developed a simplified workflow using predefined CT attenuation values to integrate EAT into the CARTO 3 system. We applied this approach in three patients with dilated
