This is a multi-center, prospective open label, feasibility study evaluating the safety and efficacy of the combined ablation procedure for the treatment of longstanding persistent atrial fibrillation.
The purpose of this feasibility study is to evaluate the safety and efficacy of the epicardial / endocardial combined procedure using the nContact Numeris®-AF Guided Coagulation System with VisiTrax® epicardially and the St. Jude Medical Therapy™ Cool Path™ Ablation Catheter endocardially to treat longstanding persistent Atrial Fibrillation (AF) patients.
Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Numeris®-AF Guided Coagulation System with VisiTrax®

The purpose of this study is to determine the change in average radiation exposure time and average procedure time following guided radiofrequency (RF) ablation among subjects undergoing t...
Comparison of Effectiveness of Ranolazine Plus Metoprolol Combination vs. FlecainidE pluS Metoprolol Combination in ATrial Fibrillation Recurrences FOllowing PhaRmacological or Electrical CardioverSion of AtRial Fibrillation
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice with a prevalence reaching 5% in patients older than 65 years and an incidence that increases progressively with...
The aim of the study LA-EU-01 was to examine the safety and the feasibility of the LAmbreTM Left Atrial Appendage Closure System in patients with non-valvular paroxymal, persistent or perm...
This is a sigle-center, prospective study to evaluate the role of D-Dimer testing in patients with atrial fibrillation receiving Dabigatran or warfarin anticoagulation therapy.
In patients with non-valvular atrial fibrillation treated with dabigatran etexilate, the level of adherence will be measured using a questionnaire, the Danish National Prescription Registr...
Physician decision making in anticoagulating atrial fibrillation: a prospective survey of a physician notification system for atrial fibrillation detected on cardiac implantable electronic devices of patients at increased risk of stroke.
The objectives of this study were to evaluate the effectiveness of a physician notification system for atrial fibrillation (AF) detected on cardiac devices, and to assess predictors of anticoagulation...
Catheter ablation for rhythm control is recommended in specific patient populations with paroxysmal, persistent, or long-standing persistent atrial fibrillation. Pulmonary vein isolation is the corner...
Deficiency of testosterone was associated with the susceptibility of atrial fibrillation. Angiotensin-II receptor antagonists were shown to reduce atrial fibrillation by improving atrial electrical re...
Radiofrequency catheter ablation of atrial fibrillation (AF) is one of the most complex ablation procedures. Both patients and operators are exposed to scattered radiation. This study evaluated the sa...
Radiofrequency ablation has become a safe and effective treatment for atrial fibrillation. We believe that referral to an electrophysiologist for consideration of ablation may allow for better rhythm ...
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.
A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.
Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.
