Low-voltage Areas Defragmentation in Sinus Rhythm for Radiofrequency Ablation of Persistent Atrial Fibrillation

NCT04045067 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 212

Last updated 2023-09-13

No results posted yet for this study

Summary

This is a study evaluating the value of defragmentation of sinus rhythmic low voltage areas in addition to isolation of pulmonary veins in the removal of recurrent atrial fibrillation. The invasive procedure will be performed according to the procedures chosen by the rhythmologist and will in no way be modified by the patient's enrollment in the study. Similarly, the frequency of consultations, date and nature of the additional examinations will be defined by the physician, with the purpose of monitoring the patient.

Conditions

Interventions

PROCEDURE

Isolation of pulmonary veins

Low voltage areas are identified and treated by radiofrequency. Atrial fibrillation is treated by heat produced by an electric current: radio frequency. This is an intervention that consists of blocking abnormal electrical activity, especially in the pulmonary veins.

PROCEDURE

Ablation by radiofrequency of low-voltage areas

The defragmentation is guided by a map of fragmented potentials, made through a topography catheter, to locate the most abnormal areas that are the target of ablation.
