Interplay of Probe Stability and Oscillation During Very‐High‐Power Short‐Duration Ablation in Pulmonary Vein Isolation for Atrial Fibrillation

open access: yesPacing and Clinical Electrophysiology, EarlyView.
This graphical abstract presents a comprehensive analysis of probe stability and oscillation during very high‐power short‐duration (vHPSD) pulmonary vein isolation (PVI) for atrial fibrillation. The findings indicate that oscillation velocity serves as a more reliable predictor of impedance drop and temperature changes than contact force alone ...

Pulmonary Vein Isolation Without Left Atrial Mapping

open access: yesIndian Pacing and Electrophysiology Journal, 2007
Background: One of the crucial points during in most approaches developed for ablation of atrial fibrillation (AF) is the ability to identify the pulmonary vein (PVs) and to accurately locate their ostia.

High-density mapping in catheter ablation of ventricular arrhythmias

open access: yesCardiologia Hungarica
Catheter ablation of ventricular arrhythmias has evolved in recent years with the development and improvement of various technologies, most notably electroanatomical navigators and multielectrode catheters that allow for high-density mapping.

Intra‐Procedural Three‐Dimensional Rotational Angiography in Cryoballoon Ablation of Atrial Fibrillation: An RCT

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The impact of various imaging techniques on the safety and outcomes of atrial fibrillation (AF) ablation remains unclear. Intra‐procedural three‐dimensional rotational angiography (3DRA) is the least used imaging method despite some benefits.

A case of premature ventricular contractions originating from the papillary muscle in the right ventricle

open access: yesJournal of Arrhythmia, 2014
A 45-year-old man with premature ventricular contractions (PVCs) underwent electrophysiological studies. Activation mapping using a noncontact electroanatomical mapping system indicated that the septal mid-apical region in the right ventricle was ...

Left Ventricular wall Thickness and Decrement Evoked Potentials in Ablation of Ischemic Ventricular Tachycardia

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Preprocedural imaging can improve the success rate of ventricular tachycardia (VT) ablation. Left ventricular wall thickness (LVWT) measured by cardiac computed tomography (CT) can be used to identify infarct regions. We sought to determine whether an association exists between left ventricular wall thickness (LVWT) as obtained ...

Renal Sympathetic Denervation Using an Electroanatomic Mapping System

open access: yesJournal of the American College of Cardiology, 2014
![Figure][1] A 54-year-old man with refractory hypertension presented for catheter-based renal sympathetic denervation. Three-dimensional (3D) geometric reconstruction of the renal arteries and real-time visualization of the ablation catheter were performed with an irrrigated straight ...

Zero‐Fluoroscopy Ablation Methods for Atrial Fibrillation: A Systematic Review and Meta‐Analysis

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Central illustration. Schematic comparison of conventional fluoroscopy guided ablation (left) and zero fluoroscopy ablation (right), enabled by electroanatomical mapping and intracardiac echocardiography for catheter navigation without X ray. The study selection process is summarized (133 records identified; 12 studies included, total n = 1998 ...
