Filter by:Post-authorization observational, prospective, follow-up study of a cohort of patients with non-valvular atrial fibrillation who are treated with direct oral anticoagulants (DOACs) to evaluate the clinical course (occurrence of stroke, major bleeding and mortality) and its correlation with clinical, pharmacokinetic (plasma concentrations), pharmacodynamic (haemostatic) and pharmacogenetic factors.
The primary objectives of this study are to identify and diagnose Atrial Fibrillation (AF), evaluate improvement in cardiovascular (CV) outcomes, improve direct oral anti-coagulant (DOAC) adherence and persistence, and better characterize participants and identify predictors of disease.
Mesh-type flexible tip (MFT) catheter is developed to generate bigger radiofrequency (RF) lesion, and contract force (CF) catheter improves the maintenance of catheter-tissue contact during atrial fibrillation catheter ablation (AFCA). The investigators compared clinical outcome of AFCA conducted by MFT catheter and CF catheter in prospective randomized manner. The investigators prospectively assigned 230 patients with AF in a 1:1 ratio to ablation by MFT catheter (FlexAbility™, Abbott Inc. USA) and CF catheter (TactiCath™, Abbott Inc. USA). The primary end point was AF recurrence after single procedure, and the secondary end point was response to antiarrhythmic drugs.
Atrial fibrillation (AF) is the most common arrhythmia in western countries and causes of up to one quarter of ischemic strokes. The randomized eHealth-based Bavarian Alternative Detection of Atrial Fibrillation study (eBRAVE-AF) tests the efficacy of an e-health based strategy for the detection of AF. The e-health-based strategy consists of a smartphone-based photophlethysmographic (PPG) screening and an ECG-based validation.
In ablation strategy for persistent Atrial Fibrillation (PsAF), ablation limited to Pulmonary Vein (PV) isolation is the most straightforward approach but the result give only 50% of arrhythmia free follow-up. Substrate modification strategies have failed to demonstrate their superiority with variable reported success rate. The Marshall network is a highly arrhythmogenic structure that has not been incorporated in current ablation strategies. The investigators sought to investigate a new ablation strategy that target systematically the vein of Marshall by ethanol infusion. This step is integrated in a new ablation strategy consisting in a global anatomical substrate based ablation including PV isolation and left atrial linear ablation (Marshall-Plan). The main objective of this study is to compare the 12 month freedom from any arrhythmia (Atrial Fibrillation (AF)/Atrial Tachycardia (AT)) between the Marshall-Plan approach and the PV isolation approach.
This interventional prospective multicenter nonrandomized clinical and epidemiological study is the first Russian study aimed at evaluating the effectiveness of a single-lead electrocardiography device (CardioQVARK) in screening for atrial fibrillation in primary health care.
The purpose of the ULTRA-HFIB Pilot is to determine the role of adjunctive renal denervation (RDN) in the prevention of Atrial Fibrillation (AF) recurrence in patients scheduled for an AF ablation procedure. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention).
The MANDATE-AF study was designed to address evidence needs in India for device-based management of AF using AT/AF (Atrial Tachycardia/Atrial fibrillation) diagnostic features and therapies such as Reactive Atrial anti tachycardia Pacing (rATP) within Medtronic Cardiac Implantable Electronic Devices (CIED)and its impact on the time to persistent AF and progression of AT/AF.
This study seeks to assess the effect of apnea (breath hold) during atrial fibrillation (AF) ablation by having all ablations performed under apnea. By prospectively studying the effects of apnea on AF ablation, the investigators wish to demonstrate its feasibility, safety and impact on patient outcomes. This is a prospective study that includes both an apnea arm and a control arm. The subjects who consent to the apnea arm will undergo an atrial fibrillation ablation with periods of apnea. The subjects who consent to the control arm will agree to have their data from their standard of care atrial fibrillation be collected for comparison.
The purpose of this study is to compare the discontinuation rates for vitamin K antagonists and for direct oral anticoagulants during their first year
