Isolation of Pulmonary Veins With PVAC GOLD in Elderly Patients

It is a prospective, randomized and double-blind clinical trial involving an invasive technique for isolation of pulmonary veins (PVAC gold) in relation to clinical treatment during an one year of segment. The patients included have paroxysmal atrial fibrillation (aged 65 years and older) refractory to antiarrhythmic treatments that do not …

Apixaban for the Reduction of Thrombo-Embolism in Patients With Device-Detected Sub-Clinical Atrial Fibrillation

Device-detected sub-clinical atrial fibrillation (SCAF) is a new disorder that has been recognized since the availability of implantable devices capable of long term continuous heart rhythm monitoring. It is characterized by one or more runs of rapid atrial arrhythmia detected by the device without symptoms and without any clinical atrial …

Evaluation of Abbreviated Versus Conventional Course of Dabigatran Etexilate Before Electric Cardioversion in Patients With Atrial Fibrillation (RE-SOUND Study)

Current guidelines recommend for stroke prevention in patients with atrial fibrillation (AF) lasting more than 48 h designated for cardioversion standard approach with anticoagulation for a minimum 3 weeks before anticoagulation. The alternative is abbreviated anticoagulation in case of using trans-oesophageal echocardiography (TEE)-guided approach with quick cardioversion if no thrombus …

Comparison Between "Conventional Monitoring" Versus "Monitoring Via Vitaphone" in the Detection of Post Ablation Atrial Arrhythmias of Paroxysmal Atrial Fibrillation

Atrial fibrillation (AF) is the most common atrial arrhythmia in the population and its incidence will increase in the coming years. Ablation of AF is a recent technique, the efficiency of which has considerably increased in recent years. Nevertheless, the success rates of ablation vary between 50% and 70% depending …

Optimal Anticoagulation for Higher Risk Patients Post-Catheter Ablation for Atrial Fibrillation Trial

This is a prospective, open-label, randomized trial to investigate whether a strategy of ongoing, long-term oral anticoagulation with rivaroxaban 15 mg daily is superior to a strategy of antiplatelet therapy, ASA 75-160 mg, alone in preventing cerebral embolic events in moderately high risk patients following successful catheter ablation for atrial …

Predictive Factors to Effectively Terminate Paroxysmal Atrial Fibrillation by Blocking Atrial Selective Ionic Currents

Background: Different research strategies aim at understanding the mechanisms underlying the maintenance of atrial fibrillation (AF), while preventing ventricular pro-arrhythmia related to the use of anti-arrhythmic drugs to restore sinus rhythm. Such aims might be achieved by drugs that effectively terminate reentrant sources identified during AF, along with an atrial …

CRyoAblation vs AntiaRrhythmic Drugs for Persistent Atrial Fibrillation Trial

The ablation of pulmonary veins is a very effective treatment for the treatment of paroxysmal atrial fibrillation. The benefit of the isolation of pulmonary veins in persistent atrial fibrillation seems to be minor and the level of scientific evidence available requires additional clinical trials to define the value of ablation …

Rate Control Therapy Evaluation in Permanent Atrial Fibrillation (RATE-AF)

Atrial fibrillation (AF) is an increasingly common cardiac condition that leads to a substantial burden on quality-of-life (QoL), an increased risk of cardiovascular events, hospitalisation and death, and significant healthcare costs for the NHS. In addition to anti-coagulation and considerations for rhythm control therapy, most patients with AF are in …

Prevention of Silent Cerebral Thromboembolism by Oral Anticoagulation With Dabigatran After Pulmonary Vein Isolation for Atrial Fibrillation

Oral anticoagulation treatment (OAC) following clinically successful catheter abla-tion of atrial fibrillation (AF) is controversial. Recent guidelines recommended con-tinuation of OAC in all patients with CHA2DS2VASc score 2 even if there is no evidence of recurrent AF (Camm JA et al., Eur Heart J 2012). The net clinical ben-efit of …

Targeting Risk Interventions and Metformin for Atrial Fibrillation (TRIM-AF)

The purpose of this study is to perform a prospective, randomized study for the reduction of atrial fibrillation (AF) burden and progression, targeting metabolic upstream therapies. The study aims to determine if metformin and/or lifestyle/risk factor modifications reduce AF burden and progression. A secondary aim will attempt to determine clinical, …
