Functional nature of electrogram fractionation demonstrated by left atrial high-density mapping.
BACKGROUND Complex fractionated atrial electrograms (CFAE) are targets of atrial fibrillation (AF) ablation. Serial high-density maps were evaluated to understand the impact of activation direction and rate on electrogram (EGM) fractionation. METHODS AND RESULTS Eighteen patients (9 persistent) underwent high-density, 3-dimensional, left-atrial mapping (>400 points/map) during AF, sinus (SR),...
متن کاملHigh-density mapping of atrial fibrillation in humans: relationship between high-frequency activation and electrogram fractionation.
INTRODUCTION Sites of complex fractionated atrial electrograms (CFAE) and dominant frequency (DF) have been implicated in maintaining atrial fibrillation (AF); however, their relationship is poorly understood. METHODS AND RESULTS Twenty patients underwent biatrial high-density contact mapping (507 +/- 150 points/patient) during AF. CFAE were characterized using software to quantify electrogra...
متن کاملNature of electrogram fractionation during atrial fibrillation.
The study by Jadidi et al1 described the locations of areas of continuously fractionated atrial electrograms during atrial fibrillation (AF) using high-resolution endocardial mapping in 9 patients with paroxysmal AF and 9 patients with persistent AF. This study then correlated these areas with the locations of fractionated atrial potentials during sinus rhythm and coronary sinus (CS) pacing in ...
متن کاملEvaluation of the characteristics of rotational activation at high-dominant frequency and complex fractionated atrial electrogram sites during atrial fibrillation
BACKGROUND High-dominant frequency (DF) and continuous complex fractionated atrial electrogram (CFAE) sites as surrogates for localized sources maintaining atrial fibrillation (AF) are potential AF ablation targets. This study aimed to evaluate the characteristics of a rotational activation at high-DF and continuous CFAE sites in AF patients. METHODS Thirty-two consecutive AF patients (5 paro...
متن کاملAutomated Detection of Complex Fractionated Atrial Electrograms In Substrate-Based Atrial Fibrillation Ablation: Better Discrimination with a New Setting of CARTO® Algorithm.
Background and purpose: Up until recently complex fractionated atrial electrogram (CFAE) ablation has been considered as time consuming and its achievement as challenging, especially for non experimented operators. Moreover, results of substrate ablation based on CFAE detection in atrial fibrillation (AF) are very disparate, mainly because of the operator's subjective electrogram visual analysi...
