Restoring Sinus Rhythm With Cardiac Resynchronization in Patients With Atrial Fibrillation (ReSync...
Heart FailureAtrial ArrhythmiaHeart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are changes in the heart beat sometimes an implantable heart device is used to control the rate and rhythm of the heart beat. In certain heart failure cases, when the two lower chambers of the heart no longer beat in a coordinated manner, cardiac resynchronization therapy may be prescribed. People who have a dangerously fast heart beat, or whose heart is at risk of stopping beating, may be in need of an electronic device called an implantable cardioverter defibrillator (ICD). Atrial tachyarrhythmia (AT) is the name for rapid beats in the upper chambers of the heart. People with AT may experience symptoms such as heart palpitations (a racing or pounding feeling in the chest), shortness of breath, dizziness, fatigue or weakness. The purpose of this study is to characterize the impact of cardiac resynchronization therapy versus cardiac resynchronization therapy with atrial therapies on the incidence, duration and termination of atrial tachyarrhythmias.

PARADISE: Predicting AF After Cardiac Surgery
Atrial Fibrillation New OnsetThe PARADISE study aims to develop and validate prediction tools to identify patients at risk of Atrial Fibrillation (AF) after cardiac surgery.
Atrial Fibrillation and Cancer: a Nationwide French Cohort Study
Atrial FibrillationCancer2 moreAtrial fibrillation (AF) is a common complication associated with cancer but the risk of AF according to the cancer localization and status as well as the risk of thromboembolisms, bleedings and mortality are poorly known. The objective of this study is to use a very large French nationwide cohort to adress thèses questions.

Atrial FibrillationPersistent6 moreThis post-market global registry will evaluate the ability of the Ablamap® Software to identify atrial fibrillation sources and guide ablation therapy in patients with atrial fibrillation.
Comparison of Pulmonary Vein Ablation With or Without Left Atrial Posterior Wall Ablation for Persistent...
Atrial Fibrillation ChronicPersistent Atrial FibrillationThe purpose of this study it to learn whether pulmonary vein isolation (PVI) along with ablation of the posterior left atrial wall (PLAW) will reduce the likelihood of atrial fibrillation (AF) recurrence in patients with persistent or long-standing persistent AF one year after an ablation procedure in comparison to a PVI ablation procedure, alone. The investigator hypothesizes that the combination of PVI plus PLAW isolation will result in a reduction in recurrence of atrial arrhythmias at one year after ablation.
CAPA-VU Trial Catheter Ablation in Paroxymal Atrial Fibrillation Based on UNIVU
Paroxysmal Atrial FibrillationCartoUnivu™ module easily integrates into the workflow of PVI with the endpoint of unexcitability of the ablation line without prolonging the procedure time. It is associated with a marked reduction in fluoroscopic dose when compared to a conventional 3D-mapping system. The aim of this prospective randomized study is to evaluate during pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) whether the use of the IIM is: 1. feasible, 2. can help to reduce fluoroscopy time and burden and 3. has an influence on the procedure duration. Study design Prospective, randomized controlled multicenter trial, open label. Randomization 1:1
AF Substrate Mapping and Guided Ablation
Persistent Atrial FibrillationIn this study, the investigators aim to identify and characterize, by means of an EnSite Velocity Research Software, the electrophysiological characteristics of substrates that sustain AF in patients with persistent AF and to test whether ablation of such patient-specific substrates might improve the acute and long-term success of conventional catheter ablation therapy.
