Development of a New Impedance Mapping System for Ablation of Atrial Arrhythmias in Patients

Atrial Arrhythmia Clinical Trial

Official title:
Desarrollo de un Nuevo Sistema de Mapeo de Impedancia Para la ablación de Las Arritmias Auriculares en Pacientes

Clinical Trial Summary

Precise identification of the atrial fibrosis is essential for successful catheter ablation of atrial arrhythmias in patients with atrial fibrillation. Voltage mapping of endocardial electrograms is currently used to delineate the anatomical substrate, but this is influenced by the direction of the activation wave front and is limited by the patient-specific thresholds. Mapping of local myocardial electrical impedance may overcome these limitations.

Clinical Trial Description

Clinical series: Patients with atrial arrythmias undergoing catheter ablation of these will be submitted to mapping of both voltage and tissue impedance. Likewise, the accuracy of the two maps identifying the extent of the substrate will be assesssed by gadolinium imaging. The impedance system is already constructed and certified for clinical research use. ;
