Concomitant Surgical Atrial Fibrillation Ablation in Double Valve Replacement

Persistent AF was defined as AF lasting more than 7 days and long-standing persistent AF as continuous AF for more than 12 months. Concomitant surgical AF ablation was offered to suitable patients as determined by the surgeon, and patients then decided whether to undergo the additional procedure. The operations were ...

Phase N/A

Left Atrial Appendage Occlusion Versus New Oral Anticoagulants for Stroke Prevention in Patients With Non-valvular Atrial Fibrillation

Atrial fibrillation (AF) is associated with a substantial risk of stroke and systemic embolism. Vitamin K antagonists are highly effective in preventing stroke in patients with atrial fibrillation and high risk of ischemic stroke. However, their use is limited by a narrow therapeutic range, increased risk of intracranial hemorrhage, the ...

Phase N/A

SmartTouch Catheter for Left Anterior Line - SmarT Line Study

Catheter ablation has emerged as a realistic therapeutic option for symptomatic atrial fibrillation (AF). The three main techniques described for ablation of persistent AF include pulmonary vein (PV) isolation, ablation based on electrogram analysis, and left atrial (LA) linear lesions. The ideal endpoint of linear lesions should be complete electrical ...


Sleep Apnea and Atrial Fibrillation Recurrence

Sleep apnea syndrome (SAS) is a common but often undiagnosed disorder associated with substantial cardiovascular morbidity and mortality. SAS prevalence in atrial fibrillation (AF) is 20% to 75%. SAS is associated with both myocardial fibrosis and electrical remodeling which both favor recurrence of AF despite medical treatment or atrial ablation. ...

Phase N/A

Ablation of Atrial Fibrillation in Heart Failure Patients

Atrial fibrillation (AF) is one of the most common arrhythmia worldwide and the risk of AF incidence increases with age. The amount of patients suffered from AF is still underestimated due to insufficient diagnosing silent AF. The incidence of patients with silent, asymptomatic AF might be approx. 80% , particularly ...

Phase N/A

Antithrombotic Treatment in Patients With Effectively Maintained Sinus Rhythm After Atrial Fibrillation Ablation

The investigators hypothesize that the strategy of OAC will be superior to antiplatelet therapy, but low dose edoxaban (30mg) will be non-inferior to standard dose edoxaban (60mg) for reducing the risk of stroke or systemic embolism in patients who underwent successful AF ablation. Although AF ablation is an effective therapy ...


Oral Anticoagulation Therapy Pilot Study

Patients undergoing successful cardiac ablation for atrial fibrillation who remain AF recurrence-free 3 months after successful ablation and continue to meet the inclusion/exclusion criteria will be screened for enrollment in the trial. After fulfilling all of the inclusion/exclusion criteria, patients who consent to participate in the study and remain AF ...


ICT-based Monitoring for Arrhythmia Detection After AF Ablation

This clinical trial is a prospective, randomized, controlled, multicenter study in patients who are capable of using and consent to use a smartphone-based ECG monitoring after ablation for atrial fibrillation. The patients will be randomly assigned to either the Holter monitoring or ICT-based centralized clinical trial monitoring system group in ...

Phase N/A

Isolation of Pulmonary Veins With the Aid of Magnetic Resonance Imaging

Atrial fibrosis is a hallmark of the AF substrate. An accurate identification and localization of myocardial fibrosis areas prior to an ablation procedure by means of LGE-MRI might help to target atrial areas harboring AF, thereby improving ablation outcomes and reducing AF recurrences. In order to test this hypothesis, we ...


Mobile Phones in Cryptogenic Stroke Patients Bringing Single Lead ECGs to Detect Atrial Fibrillation

Rationale: A standard work-up of stroke patients to identify a cause of stroke consists of Computed Tomography (CT), CT angiography of head and neck arteries, transthoracic echocardiography, 12-lead 10-seconds electrocardiogram (ECG), blood tests and 24-hour ECG monitoring. A stroke is called "cryptogenic" if no cause can be determined after standard ...
