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 ...

Principles of electroanatomic mapping.

Indian pacing and electrophysiology journal, 2008
Electrophysiologic testing and radiofrequency ablation have evolved as curative measures for a variety of rhythm disturbances. As experience in this field has grown, ablation is progressively being used to address more complex rhythm disturbances.

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.

High‐density mapping of de novo focal atrial tachycardias using a new software: Protected low‐voltage areas by zones of conduction delay

Journal of Arrhythmia, 2020
Background The pathophysiological mechanism of focal atrial tachycardias (AT) remains obscure. Methods Fifteen patients (6 males, age 45 ± 18) with focal AT underwent high‐density activation mapping using a new software called extended early‐meets‐late ...

Techniques for Identification of Left Ventricular Asynchrony for Cardiac Resynchronization Therapy in Heart Failure [PDF]

, 2005
The most recent treatment option of medically refractory heart failure includes cardiac resynchronization therapy (CRT) by biventricular pacing in selected patients in NYHA functional class III or IV heart failure. The widely used marker to indicate left

Modified Anatomical Ablation Strategy for Mitral Isthmus

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Durable mitral isthmus (MI) block remains challenging in persistent atrial fibrillation (AF) ablation. Ethanol infusion into the vein of Marshall (EI‐VOM) enhances efficacy, but the minimal endocardial ablation extent post‐EI‐VOM is undefined.

Ventricular tachycardia in ischemic cardiomyopathy; a combined endo-epicardial ablation as the first procedure versus a stepwise approach (EPILOGUE) - study protocol for a randomized controlled trial [PDF]

, 2015
Background: The role of epicardial substrate ablation of ventricular tachycardia (VT) as a first-line approach in patients with ischemic heart disease is not clearly defined.

Long‐Term Outcomes of Radiofrequency Atrioventricular Node Ablation in a Real‐World Population

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background While interventional strategies have expanded the options for long term rhythm restoration, rate control continues to play a pivotal role in the treatment of atrial arrhythmias; however, pharmacologic strategies alone often fail in achieving effective rate control.

The utility of 24-h electrocardiogram recordings for the prediction of a sufficient number of premature ventricular complexes and mapping strategy during catheter ablation

Frontiers in Cardiovascular Medicine
Background and aimsAn insufficient number of premature ventricular complexes (PVCs) during catheter ablation (CA) may prohibit adequate mapping of the site of origin. Parameters to predict this situation have not been established.
