Active clinical trials for "Atrial Fibrillation"

This study will examine the effect of detraining as a clinical tool to prevent recurrence of lone paroxysmal atrial fibrillation (AF) and improve quality of life. Persons who engage in endurance activity with AF will be randomly assigned to undergo an 8-week period of detraining or encouraged to maintain their current level of exercise. Participants will receive a handheld device called AliveCor that can record an electrical tracing of the heart rhythm by pressing down with ones' thumbs. The amount of arrhythmia and symptoms will be recorded. The research team hypothesizes that among athletes with lone AF, an 8-week period of detraining will not affect atrial fibrillation recurrence or quality of life.

This study is to assess the effectiveness and safety of using cryoballoon ablation comparing with anti-arrhythmic drug therapy as initial treatment for naive patients with persistent atrial fibrillation.

Pulmonary vein isolation (PVI) using the cryoballoon has been proven equal to RF-PVI and is widely used. High Power Short Duration Ablation in RF-PVI has been successfully tested in several trials. Prospective data comparing both strategies is lacking. This trial will compare acute success rates, safety and foremost long-term outcome of two different PVI strategies (HPSD-PVI vs. cryo-PVI).

To compare of atrial arrhythmia incidence in patients with coronary artery disease and atrial fibrillation history, undergoing either coronary artery bypass grafting plus temporary spinal cord stimulation or coronary artery bypass grafting alone

The purpose of this randomized, double blind, placebo-controlled, superiority clinical trial was to assess clinical efficacy of potassium canrenoate - canrenone in rapid conversion of atrial fibrillation to sinus rhythm.

The aim of our study is to investigate if LTCM's are superior to implantable loop recorders in detecting atrial fibrillation after pulmonary vein isolation. This study will provide insights on a possible alternative for detection of arrhythmia.

There is growing awareness of the importance of electrical rotors to the maintenance of atrial fibrillation (AF). Recent work in our laboratory has found that AF evolves over time, from rapid, focal activation, next to transitional rotors, and finally to stable, long duration rotors, whose locations are frequently separate from the transitional rotor sites. This project will test the hypothesis that mapping and ablation of the transitional rotors sites may prevent atrial fibrillation from progressing to sustained atrial fibrillation, and therefore increase the AF initiation threshold. The investigators will test this hypothesis during clinically-indicated electrophysiology study prior to ablation of symptomatic AF.

The purpose of this study is to compare effectiveness of two substrate modification approaches in long-standing persistent atrial fibrillation patients, and hypothesized that a substrate-based, individualized substrate modification (ISM)approach should be superior to traditional stepwise ablation(SA). To the best of investigator's knowledge, this was the first study to evaluate the "real" substrate by means of electro-anatomic mapping and to perform "true" substrate modification in long standing persistent atrial fibrillation ablation(LPAF).

The aim of this study is to assess the effect of left atrial appendage excision on atrial fibrillation recurrence and incidence of stroke in patients with persistent and long-standing persistent atrial fibrillation undergoing surgical ablation.

Cardiovascular diseases are the number 1 cause of death globally and represent a major economic burden on health care systems. The investigators have developed a novel integrated care concept (NICC) which combines telemedicine with intensive support by a call center, an integrated care network including in- and outpatient care providers and guideline therapy for patients with heart failure (HF), atrial fibrillation (AF) or therapy resistant hypertension (TRH). The aim of the study is to show that NICC is preferable over guideline therapy alone. We aim at including approximately 890 patients. Patients could be enrolled either directly at the Care-Center (location: University Hospital of Rostock) or at one of the advanced treatments rooms of the Care-Center (outpatient cardiological specialist practices). The ethics commission's statement of the University of Rostock is available for amendment 2 since 20.08.2019 at the number A2017-0117.
