NCT ID: NCT05393180 Recruiting - Clinical trials for Chronic Atrial Fibrillation

CONVERGE Post-Approval Study (PAS)

Start date: April 13, 2022
Phase: N/A
Study type: Interventional

The primary objective of CONVERGE PAS is to evaluate clinical outcomes (peri-procedural and long-term) in a cohort of patients treated during commercial use of the EPi-Sense® Guided Coagulation System or EPi-Sense STâ„¢ Coagulation System to treat symptomatic long-standing persistent atrial fibrillation (AF) patients who are refractory or intolerant to at least one Class I and/or III AAD.

NCT ID: NCT03295422 Recruiting - Clinical trials for Persistent Atrial Fibrillation

Comparison of Two Pulmonary Vein Ablation Techniques for Persistent AF

Start date: August 25, 2017
Phase: N/A
Study type: Interventional

Investigator initiated, randomized controlled trial of two radiofrequency (RF)ablation protocols currently performed in the electrophysiology lab, but have not been studied prospectively to identify which, if either technique, is superior for individuals with persistent atrial fibrillation (AF). Two-hundred subjects will be consecutively enrolled and randomized to either pulmonary vein isolation only or pulmonary vein isolation plus posterior left atrial wall isolation

NCT ID: NCT02696265 Recruiting - Clinical trials for Chronic Atrial Fibrillation

CFAE/Spatiotemporal Dispersion Guided Ablation Versus PVI Guided Ablation in Persistent AF

CIPA
Start date: October 12, 2016
Phase: N/A
Study type: Interventional

Objective: The purpose of this study is to compare the efficacy and safety of ablation of Atrial Fibrillation (AF) drivers marked by spatiotemporal dispersions and Complex Fractionated Atrial Electrocardiograms (CFAEs) to Pulmonary Vein Isolation (PVI) based ablation in patients with persistent AF. Hypothesis: CFAE/spatiotemporal dispersion guided ablation will increase AF free survival compared to a PVI guided ablation. Patient population: Patients with persistent AF will be randomized based on a 2:1 ratio into one of two study arms: - CFAE/spatiotemporal dispersion guided ablation: CFAE mapping and ablation during AF aimed at restoring sinus rhythm during ablation. - PVI guided ablation: wide antral pulmonary vein isolation during mapping catheter control of pulmonary vein signals

NCT ID: NCT01892774 Active, not recruiting - Clinical trials for Chronic Atrial Fibrillation

Impact of the Pulmonary Vein Isolation on Exercise Capacity in Patients With Chronic Atrial Fibrillation

Exercise
Start date: January 2010
Phase:
Study type: Observational

This study would assess the impact of radio-frequency catheter ablation on exercise capacity and quality of life in long-standing persistent atrial fibrillation (LSP-AF) patients
