Active clinical trials for "Atrial Fibrillation"

The safety of edoxaban treatment will be examined using real-world clinical evidence from adult patients with non-valvular atrial fibrillation (NVAF) indications in routine clinical practice.

The purpose of this study is to better understand the following aims: Aim 1: To evaluate the rate of recurrent Atrial Fibrillation (AF)/Atrial Flutter (AFL) in hematopoietic stem call transplant (HCST) patients with incident AF/AFL identified during the initial 30 days of the transplant Aim 2: To evaluate incident episodes of 1) stroke/TIA; 2) other thromboembolic events (not stroke/TIA); 3) Heart failure events; 4) Ischemic heart events Aim 3: To evaluate overall implantation safety in this population

The purpose of this study is to assess the effects of Dexmedetomidine (DEX), on heart rate control in patients with rapid atrial fibrillation (AF) through a pragmatic, randomized, double blinded study comparing the addition of Dex or placebo to standard of care (SOC) treatment.

Recent studies demonstrated that radiofrequency isolation of the pulmonary veins (PVI) is a superior alternative to antiarrhythmic drug therapy in patients with symptomatical paroxysmal atrial fibrillation (AF). A substantial proportion of patients undergoing elective cardiac surgery also suffer from atrial fibrillation. No evidence exists if epicardial PVI is beneficial in patients with a history of AF undergoing coronary bypass surgery (CABG) for the concomitant treatment of AF. The investigators aim to establish the effectiveness of incorporating epicardial pulmonary vein isolation into elective cardiac surgery.

To determine the efficacy of cardioversion and amiodarone for cardiac patients who develop postoperative atrial fibrillation

Studies have shown that taking drugs to stay out of AF has limited success. This research is designed to study heart rhythm after surgical therapy, namely by measuring if there are benefits to having surgery to treat Atrial Fibrillation (AF) with the Cardioblate CryoFlex Surgical Ablation System. The system is approved and commercially available with CE mark. The purpose of this study is to support clinical evidence that the Cardioblate System is safe and effective to treat AF.

Primary Objective: - Evaluate the effect of dronedarone versus placebo (standard therapy) in slowing the progression of adverse left atrial remodeling in patients with atrial fibrillation (AF) following 12 months of treatment. Secondary Objectives: Evaluate the effects of dronedarone versus placebo on left atrial function; Evaluate the effects of dronedarone versus placebo on left atrial dimension; Evaluate the effects of dronedarone versus placebo on left ventricular function (LVEF, E, E', A, E/E') Evaluate the safety and tolerability of dronedarone.

This is a multi-center, prospective open label, feasibility study evaluating the safety and efficacy of the combined ablation procedure for the treatment of longstanding persistent atrial fibrillation.

The purpose of this study is to assess the safety and performance of the Hansen Medical Sensei Robotic System and Artisan Catheter when used to robotically manipulate RF ablation catheters for the treatment of paroxysmal atrial fibrillation (irregular heartbeats originating in the upper chambers of the heart).

The purpose of this study is to compare the efficacy, safety and efficiency of CARTO® 3 system guided THERMOCOOL® catheter ablation and fluoroscopy guided Pulmonary Vein Ablation Catheter® (PVAC®) guided ablation for the treatment of paroxysmal atrial fibrillation.
