Background Ablation index (AI) is a new lesion quality marker that has been demonstrated
to allow a high single‐procedure arrhythmia‐free survival in single‐center studies. This …

Purpose Since the introduction of catheter ablation as a mainstream treatment for atrial
fibrillation (AF), several technical improvements have been put forward. In this contest …

This study aimed to verify the reliability of ablation index (AI) for ablation lesion estimating
with different settings for radiofrequency (RF) parameters: power, impedance, contact …

Introduction Radiofrequency (RF) ablation is a commonly used tool in the invasive
electrophysiology laboratory to treat a variety of rhythm disorders. Reliable creation of …

Introduction The aim of this study was to investigate electrophysiological findings in patients
with arrhythmia recurrence undergoing a repeat ablation procedure using ultra–high …

Introduction The ablation index (AI) and lesion size index (LSI) are novel markers for
predicting the ablation lesion quality, however, collateral damage is still a concern. This …

Background Catheter ablation for atrial fibrillation (AF) traditionally requires the use of
circular mapping catheter (CMC) for pulmonary vein isolation (PVI). This study aimed to …

This document provides an overview of current problems and trends in the catheter ablation
of atrial fibrillation, summarizes the opinions of specialists, obtained during a web-based …

Background: Data on the results of ablation for atrial fibrillation (AF) in Poland are scarce.
