Short- and long-term experience in pulmonary vein segmental ostial ablation for paroxysmal atrial fibrillation* [PDF]

, 2006
Introduction: Segmental ostial pulmonary vein isolation (PVI) is considered a potentially curative therapeutic approach in the treatment of paroxysmal atrial fibrillation (PAF).

Bachmann's Bundle‐Related Atrial Tachycardias Following Catheter Ablation of Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Atrial tachycardias (AT) after radiofrequency ablation (RFA) of atrial fibrillation (AF) may utilize Bachmann's bundle (BB). Due to their epicardial location, these ATs remain poorly understood. Objective To describe the electrophysiologic and anatomic basis of BB‐related ATs.

Inflammatory and Myocardial Biomarker Response Following Pulmonary Vein Isolation: Cryoballoon Versus Balloon‐in‐Basket Pulsed Field Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Cryoballoon ablation (CB) is a well‐established thermal technique for pulmonary vein isolation (PVI), while balloon‐in‐basket pulsed field ablation (BiB‐PFA) represents a novel non‐thermal alternative. Both single‐shot systems may trigger systemic inflammation and myocardial injury, yet direct comparisons are lacking.

High-resolution mapping and ablation of recurrent left lateral accessory pathway conduction

Journal of Arrhythmia, 2017
Proper localization of the anatomical target during ablation of the accessory pathways (AP) and the ability to detect clear AP potentials on the ablation catheter are crucial for successful AP ablation.

Acute Efficacy of Pulsed‐Field Ablation of the Mitral Isthmus Using a Pentaspline Catheter and Two Different Ablation Settings

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction There is limited data regarding the use of pulsed‐field ablation (PFA) for mitral isthmus (MI) ablation in patients with non‐paroxysmal atrial fibrillation (AF). Our aim was to assess the acute efficacy of MI ablation using a pentaspline PFA catheter with two different ablation settings.

Is cryoballoon ablation preferable to radiofrequency ablation for treatment of atrial fibrillation by pulmonary vein isolation? A meta-analysis.

PLoS ONE, 2014
ObjectiveCurrently radiofrequency and cryoballoon ablations are the two standard ablation systems used for catheter ablation of atrial fibrillation; however, there is no universal consensus on which ablation is the optimal choice.

Averaged Impedance Drop Estimates Conduction Gap During Pulmonary Vein Isolation in Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background EnSite X provides a module to filter oscillated generator impedance signals due to cardiac beating/respiration (averaged impedance drop, AID). TactiFlex ablation catheter Sensor Enabled (TFSE) is the latest product to incorporate a contact‐force sensor with a flexible tip but without lesion‐estimating parameters.

Catheter ablation of right ventricular outflow tract tachycardia using contact force guidance [PDF]

, 2014
Outflow tract tachycardias (OTT) originating from the right or left ventricular outflow tract are thought to be benign. However, symptoms can be disabling and deterioration of left ventricular function may occur with a high arrhythmia burden.

Approval Lag for Ablation Catheters: A Comparative Analysis of Regulatory Timelines in the European Union, United States, and Japan

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Approval timelines for ablation catheters differ across major markets, potentially delaying clinical access. This study aimed to quantify approval lags for contemporary ablation catheters across the EU, the US, and Japan. Methods We retrospectively identified therapeutic ablation catheters with documented approval dates in the ...
