A Prospective Study of Medical Therapy Against Cryoballoon Ablation in Symptomatic Recent Onset Persistent AF

The total AF history should be shorter than 24 months. Symptomatic patients can be included if they have had within the last year at least 2 episodes of documented AF, lasting minimal 30 sec. One episode in the entire history should have lasted more than 48 h, requiring electrical or ...

A Pilot Study of Edoxaban in Patients With Non-Valvular Atrial Fibrillation and Left Atrial Appendage Closure

This is a single site, PI initiated pilot study. This study will enroll up to 75 patients who are clinically indicated for a Left Atrial Appendage (LAA) closure with the commercially available WATCHMAN device. Subjects will be enrolled if they meet study inclusion/exclusion criteria and have a successful LAA closure. ...

The Effect of Chest Tubes Using Active Clearance Technology on the Incidence of Postoperative Atrial Fibrillation

Data will be collected and stored at the department of surgery of Montreal Heart Institute. Only the principal investigator and study coordinators will have access to the database. The primary analysis will be an intention-to-treat (ITT) analysis comparing the POAF rate in the PleuraFlow group to the POAF rate in ...

Early Treatment of Atrial Fibrillation for Stroke Prevention Trial

EAST prospectively tests the hypothesis that an early, structured rhythm control therapy based on antiarrhythmic drugs and catheter ablation can prevent atrial fibrillation (AF) related complications in patients with AF when compared to usual care. Patients will be randomized to early therapy or usual care. In the early therapy group, ...

Left Atrial Thrombus Reduction - Effect of Dabigatran Versus Phenprocoumon

Bakground and study rationale: Left atrial (LA) thrombi are found in 2.5 - 18% of subjects with atrial fibrillation (AF) depending on the subject population. Subjects with LA thrombi have a particularly increased risk for cerebral and peripheral embolism. Consequently, oral anticoagulation is recommended in those subjects. Transesophageal echocardiography (TEE) ...

Low Dose of Diltiazem for Rate Control of Atrial Fibrillation

This study is to show the efficacy and safety of low dose diltiazem for the treatment of atrial fibrillation with rapid ventricular response in emergency room. We will compare the standard dose of diltiazem(0.25mg/kg) with low dose diltiazem(0.1mg/kg)in atrial fibrillation with rapid ventricular response in ED.

Irbesartan and Adhesion Molecules in AF

Primary Objective: The aim of the study is to assess that blocking the angiotensin II type 1 receptor reduces systemic levels of oxidative stress markers and adhesion molecules by more than 25% compared to placebo in patients with persistent/permanent atrial fibrillation. Primary Target Parameter: The primary target parameter is defined ...

Phase

Line Versus Spot Ablation in Persistent Atrial Fibrillation

This randomized study deals with two different ablative treatment strategies for persistent atrial fibrillation: a more anatomically guided linear ablation scheme with encircling of the ipsilateral pulmonary veins (PV), a left atrial roof line and an anterior line bridging the anterior mitral anulus to the ostium of the left superior ...

Phase

A Prospective Randomized Study Comparing Radiofrequency Energy With Cryoenergy

Transvenous pulmonary vein (PV) isolation using radiofrequency energy is an effective treatment for atrial fibrillation (1-4). However, rare but potentially life threatening complications such as thromboembolism (5), PV stenosis (5-10), left atrium-oesophageal fistula (11) and inflammatory syndromes (12) have been described. In preliminary studies an alternate approach using cryoenergy induces ...

Pulmonary Vein (PV) -Isolation: Arrhythmogenic Vein(s) Versus All Veins

BACKGROUND Atrial fibrillation ablation procedures typically involve isolation of all pulmonary veins (PVs), yet the need for such an extensive ablation strategy in all patients is unclear. OBJECTIVE: We conduct a randomized study comparing the safety and effectiveness of two interventional ablation techniques for treatment of paroxysmal atrial fibrillation: the ...
