Purpose Ablation of atypical atrial flutter (AAFL) can be challenging. High-density (HD)
mapping of ablation targets may potentially increase procedural success and freedom from …

Background: The existence of epicardial connection (s)(ECs) between the pulmonary veins
(PVs) and atrium may hinder establishing a complete PV antrum isolation (AI)(PVAI) in …

Conduction velocity (CV) slowing is associated with atrial fibrillation (AF) and reentrant
ventricular tachycardia (VT). Clinical electroanatomical mapping systems used to localize AF …

To provide an overview of the current application of high‐density mapping (HDM) in the
mechanism of complex atrial tachycardias (ATs). Complex ATs are frequently scar‐related …

Intracardiac mapping of accessory pathways has continued to evolve and contribute to high
success rates for catheter ablations in pediatrics, ranging from 78% to 98%. 1, 2, 3 With 3 …

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

Background: We aimed to share our experience of intra-atrial reentrant tachycardia mapping
and ablation with a new grid-style multielectrode high-density mapping catheter (Advisor™ …

Background: A 61-year-old male with Steinert Dystrophy and prior history of cardiac
implantable device complained of highly symptomatic right atrial tachycardia. Unresponsive …

Scar-mediated atrial and ventricular arrhythmias are leading indications for hospitalization
and risk factors for sudden cardiac death in the postoperative congenital heart population. 1 …

Multipolar mapping catheters such as the Pentaray®(Biosense Webster) and Orion®(Boston
Scientific) are often used for creating high-density maps rapidly in the patients with …
