Active clinical trials for "Atrial Fibrillation"

This is a prospective, multicenter, non-randomized observational study of subjects 18 years and older undergoing RF ablation with drug refractory recurrent symptomatic paroxysmal Atrial Fibrillation (AF).

The primary objective of this study is to examine the safety profile of Eliquis in Korean nonvalvular atrial fibrillation patients.

The investigators goal in this study is to examine the feasibility and efficacy of AliveCor iphone case monitoring device in monitoring patients after AF ablation by comparing transmissions using Alive Cor with transmissions from a traditional transtelephonic monitor (TTM). A secondary goal is to assess the ease of use of AliveCor device compared to traditional TTM system from the patient's perspective

Atrial Fibrillation is an abnormal heart rhythm that can occur after coronary heart bypass graft operations. How often this happens and what other problems occur for a person after these operations needs to be better understood. This study uses a device called the Reveal XT, a small device that records heart rhythms to track a patient's heart rhythms after the bypass surgery. The device is implanted at the time the bypass graft is made. The information that is gathered for this study will help physicians to provide better treatment and follow-up of the patients under their care.

This cohort study aims to evaluate thoracoscopic left atrial appendage excision plus atrial fibrillation ablation versus oral anticoagulants for the prevention of stroke and non-central nervous systemic embolism in patients with atrial fibrillation and thromboembolism.

To evaluate the efficacy of catheter ablation and rate control in heart failure patients with atrial fibrillation.

The purpose of this study is to determine if there is a rise in serum high sensitivity troponin T (a marker for heart muscle injury) following a direct current cardioversion (shock therapy) used for patients with atrial fibrillation. This will help us determine if direct current cardioversion results in damage to the heart muscles in a sufficient amount to cause a rise in high sensitivity troponin T.

To investigate whether apelin can be used as an indicator to predict postoperative atrial fibrillation in patients with coronary atherosclerotic heart disease, and to provide an objective basis for the clinical selection of a preventive intervention program for atrial fibrillation.

The purpose of this study is to evaluate the impact of pre-ablation fibrosis on scar formation in the left atrium of the heart. This will be assessed by delayed enhancement magnetic resonance imaging and will be looked at in patients who have undergone successful open irrigated cooled-tipped radio-frequency ablation of paroxysmal atrial fibrillation. Follow-up after ablation will be for 12 months.

This is a multicenter, double-blind, randomized trial to assess the efficacy and safety of colchicine for post-pericardiotomy syndrome prevention, post-operative effusions prevention, and post-operative atrial fibrillation prevention.
