Background: Recurrences of atrial fibrillation (AF) after pulmonary vein isolation (PVI) are
mainly due to pulmonary vein reconnection. However, a growing number of patients have …

Ablation of atrial fibrillation (AF) is the cornerstone therapy for patients with symptomatic AF
resistant to anti-arrhythmic drugs or as first-line therapy, and is based on permanent …

Background Defining diastolic slow-conduction channels within the borderzone (BZ) of scar-
dependent re-entrant ventricular tachycardia (VT) is key for effective mapping and ablation …

Introduction A recently introduced grid mapping catheter (GMC) is designed for better
electrode‐tissue contact and can collect bipolar signals both along and across the splines …

Background Multipolar catheters provide high‐density mapping which may reduce the
procedural duration and improve the success of catheter ablation (CA) for focal arrhythmias …

Mapping of scar‐related atrial tachycardias (AT) can be challenging even with the use of
high‐density (HD) mapping catheter. AdvisorTM HD Grid is the only directional HD mapping …

Abstract Background The Advisor™ HD Grid mapping catheter (Abbott Laboratories;
Chicago, IL) allows for bipolar electrogram collection in both orthogonal and perpendicular …

Background The conventional mapping approach for the atrioventricular accessory pathway
(AP) involves point-by-point mapping to identify the connection sites of the AP to the atria or …

Purpose Different authors have described three-dimensional (3D) voltage mapping of the
Koch's triangle (KT) in order to find low-voltage bridges (LVB) as targets for a successful …

Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. Yet tools
and techniques used for confirmation of PVI vary greatly, and it is unclear whether the use of …
