Prospective Database for Prediction of Atrial Fibrillation in Pacemaker and ICD Patients

Atrial fibrillation (AF) is associated with a five-fold increased risk of cerebrovascular stroke. While the risk of stroke in patients with known AF can be calculated via AF stroke prediction risk scores, the prediction of AF occurrence per se in individual patients remains difficult. We will recruit 250 patients with ...

Phase N/A

Austrian Left Atrial Appendage Closure Registry

Left atrial appendage (LAA) occlusion (LAAC) has been introduced to treat patients with indication of oral anticoagulation (OAC) for atrial fibrillation (AF) with contraindication to OAC. This registry aims to document all LAAC procedures in Austria.

Phase N/A

AF Ablation Based on High Density Voltage Mapping and CFAE

Fifty patients with persistent atrial fibrillation will be randomized a 1:1 ratio to each group. A test group includes those who undergoing ablation targeting low voltage areas which contains complex fractionated trial electrogram in addition to pulmonary vein isolation and a control group includes who undergoing pulmonary vein isolation only.

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 ...

Phase

Effect of Low Dose ColchiciNe on the InciDence of POAF

AF after cardiac surgery leads to excess mortality and morbidity. Colchicine was used in several studies to lower the incidence AF but the results were generally disappointing. There was no benefit in reducing AF and there was a high incidence of GI side effects especially diarrhea, often leading to stopping ...

Phase

Clinical Trial for Optimal Novel Oral Anticoagulant (NOAC) Schedule Immediate Before Catheter Ablation for Atrial Fibrillation

This study is to evaluated the interruption schedule of NOAC in patients who undergo atrial fibrillation ablation. The investigators will compare the bleeding complications were classified as major and minor bleeding, thromboembolic, vascular complications, Re-admission and increased in the length of hospital stay during the 30-day post-radiofrequency catheter ablation(RFCA) period ...

Phase N/A

A Genomic Approach to Warfarin Dose Prescription in Admixed Caribbean Hispanics

Despite the substantial number of work published over the past years in different populations around the world, a fundamental gap remains in understanding whether and how genomic admixture and polymorphisms in warfarin-related pharmacogenes account for the high inter-individual dose variability observed in Caribbean Hispanic patients. In addition to being a ...

Phase N/A

Treatment of Atrial Fibrillation in Patients by Pulmonary Vein Isolation in Combination With Renal Denervation or Pulmonary Vein Isolation Only

The target group of patients are subjects ages <65 years, with paroxysmal or persistent atrial fibrillation, who have out of range hypertension (systolic >140 mmHg or >130/80 mmHg in diabetics and patients with chronic renal disease) or signs of sympathetic overdrive. Patients should use at least 2 anti-hypertensive's or should ...

Phase N/A

Beat-to-beat Variability in Persistent Atrial Fibrillation

Heart rate variability (HRV) in patients with atrial fibrillation (AF) is hardly studied. Though a reduced HRV in patients with heart failure and reduced ejection fraction (HFrEF) has been associated with poor prognosis. Data on HRV in AF-patients without a reduced ejection fraction is lacking. We hypothesize that those patients ...

Phase N/A

Hybrid Ablation of Persistent and Long-standing Persistent Stand-alone Atrial Fibrillation

Hybrid ablation (i.e. surgical thoracoscopic ablation, followed by catheter endocardial ablation) represent a new treatment option for patients with atrial fibrillation. 60 patients will undergo a two-stage, hybrid ablation, all of them will have an ECG monitoring device implanted and will be followed for up to three years. Neurological safety ...
