Prospective Record Of the Use of Dabigatran in Patients With Acute Stroke or TIA

The multi-center, prospective PRODAST study is investigating patients with non-valvular atrial fibrillation (AF) who experienced an ischemic stroke or a transient ischemic attack (TIA) recently ( 1 week) both with and without previous oral anticoagulation. It consists of a baseline visit and a 3 months central follow-up for patients who ...

Phase N/A

Predictors for Recurrence of Atrial Fibrillation After Electrical Cardioversion

In patients with persistent atrial fibrillation (AF), electrical cardioversion is very effective in restoring sinus rhythm if modern, biphasic cardioverters are used. However, approximately 50 per cent of the successfully cardioverted patients experience a recurrence of AF within a few weeks. Therefore, valid predictors for AF recurrence would be of ...

Phase N/A

Atrial Fibrillation Prediction Trial.

Atrial Fibrillation (AF) is a common arrhythmia with a prevalence of 1.5-2%. This prevalence increases significantly after 80 years of age. In the presence of the Arrhythmia the risk of stroke increases five fold while the congestive heart failure and the mortality rates are increasing significantly also.After the appearance of ...

Phase N/A

Dynamic Changes in SDF-1 Levels in Acute and Stabilized Heart Disease

The study considers changes in SDF-1 levels in response to treatment of cardiac disease (myocardial infarction, heart failure or atrial fibrillation). SDF-1 levels will be measured at the acute stages of the disease, after stabilization and at longer term as detailed below. Levels of SDF-1 will be correlated to the ...

Phase N/A

Thromboembolic and Bleeding Risk Stratification in Patients With Non-valvular Atrial Fibrillation

Patients with Atrial Fibrillation (AF) have an excessive risk of arterial thromboembolic disease and heart failure, resulting in higher rates of cardiovascular and all-cause mortality in this population. Prevalence and incidence of Non-Valvular AF (NVAF) is rapidly increasing across developed countries. cardiovascular (CV) and all-cause mortality rates related to AF ...

Phase N/A

CoolLoop Paroxysmal Atrial Fibrillation

This clinical investigation evaluates the safety of cryoablation (sclerotherapy of muscle tissue of the heart by freezing) in paroxysmal atrial fibrillation with the newly developed CoolLoop cryoablation catheter. A further aim of the investigation is the evaluation of the efficacy and average duration of the applied procedure.

Clinical Usefulness of Virtual Ablation Guided Catheter Ablation of Atrial Fibrillation: Prospective Randomized Study

Radiofrequency catheter ablation is highly effective in the treatment of patients with persistent atrial fibrillation. In order to decrease the recurrence rate after catheter ablation, the investigators propose to apply 'virtual' ablation on patient-specific atria by simulating 3D atrial computer model. The investigators will test with five different set of ...

Phase N/A

Combined Endoscopic Epicardial and Percutaneous Endocardial Ablation Versus Repeated Catheter Ablation in Persistent and Longstanding Persistent Atrial Fibrillation

This is a prospective, randomized (2:1) multicenter trial to investigate the optimal treatment of Persistent and Longstanding Persistent AF referred for Radiofrequency (RF) ablation.The study objective is to compare the efficacy and safety of two interventional approaches, in preventing the recurrence of AF in symptomatic, drug refractory patients with persistent ...

Phase N/A

Plasma Aldosterone Levels and Atrial Fibrillation Reduction (ALDO-AF Study)

Atrial fibrillation (AF) is the most common cardiac arrhythmias with a constantly growing prevalence. Two main techniques are used today to restore sinus rhythm: electrical cardioversion and radiofrequency ablation. Radiofrequency ablation has become a recognized and effective treatment of AF. Despite a relatively high success rate (about 80%), a substantial ...

Phase N/A

The Effect of Additional Propacetamol Infusion on Post Procedural Outcome and Opioid Consumption During Catheter Ablation of Atrial Fibrillation.

Sedation for catheter ablation of atrial fibrillation should be performed to achieve analgesia, immobilization, and maintenance of airway. Various anesthetic agents such as propofol, dexmedetomidine, and midazolam were investigated to achieve this goal. However, propofol and midazolam causes respiratory depression and dexmedetomidine occasionally accompanies hypotension or hypertension and bradycardia. Therefore, ...
