Active clinical trials for "Atrial Fibrillation"

The purpose of this study is to evaluate the effects of a single intravenous infusion of K201 compared to placebo in a dose escalating manner on conversion to sinus rhythm, reduction of subject's symptom score, and safety.

This study examines the impact of a breathing training intervention on cardiorespiratory sensations and anxiety in adults with cardiac arrhythmias.

There is no study comparing safety/efficacy of externally vs internally cooled tip catheters in patients undergoing ablation for paroxysmal atrial fibrillation (pAF). The primary objective is to compare safety and efficacy of externally irrigated-tip catheter versus internally irrigated-tip catheter in achieving long term electrical isolation (EI) of pulmonary veins (PV) in paroxysmalatrial fibrillation (pAF).

This is a randomized controlled study of the Bard High Density Mesh Ablation System for treatment of paroxysmal atrial fibrillation. This study will determine if the HD Mesh Ablation System is as safe as and more effective than anti-arrhythmic drugs.

The purpose of this study is to test the safety and efficacy of the Epicor LP Cardiac Ablation System for treating permanent atrial fibrillation during concomitant open chest and/or open heart surgery for one of more of the following procedures: mitral valve repair or replacement, aortic valve repair or replacement, tricuspid valve repair or replacement, coronary artery bypass surgery or patent foramen ovale (PFO closure).

Concomitant AF ablation with HIFU in patients with persistent or long standing persistent AF undergoing CABG will be superior in restoring SR, compared with patients with persistent or long standing persistent AF undergoing CABG treated with best medical treatment according to ACC/AHA/ESC 2006 guidelines and no AF ablation.

Primary Objective: Demonstrate the efficacy of Dronedarone in preventing major cardiovascular events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death) or unplanned cardiovascular hospitalization or death from any cause in patients with permanent Atrial Fibrillation [AF] and additional risk factors Secondary Objective: Demonstrate the efficacy of Dronedarone in preventing cardiovascular death This was an event-driven study where a common study end date [CSED] was to be determined by Steering Committee based on the number of events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death).

The purpose of this study is to demonstrate the safety and effectiveness of biventricular pacing over conventional right ventricular pacing in patients with persistent or permanent, symptomatic atrial fibrillation undergoing atrioventricular (AV) node ablation and permanent pacing therapy.

Multi-center, single-arm, prospective, post-market study of LAmbre™ LAA Closure System. To evaluate immediate and long term procedural success of Lifetech LAmbre™ occluders in patients.

The purpose of this observational registry is to prospectively collect procedure efficiency, safety and acute and long term outcome data from catheter ablation procedures as treatment of paroxysmal atrial fibrillation, using the following treatment modalities: Cryoballoon ablation Manual guided RF ablation using Contact Force catheters Remote Magnetic Navigation guided RF ablation with e-Contact and high power settings Remote Magnetic Navigation guided RF ablation with e-Contact and low power settings
