Filter by:Previous evidence indicated that the outcomes of both video-assisted thoracoscopic surgical ablation and percutaneous radiofrequency ablation therapy for persistent atrial fibrillation (AF) were unsatisfied. Recently, hybrid ablation therapy for AF had encouraging outcomes. However, there were no randomized, controlled clinical studies to prove the effectiveness of this new strategy. This study is aimed to compare the outcomes of hybrid ablation with video-assisted thoracoscopic surgical ablation for persistent AF with enlarged left atrium.
Patients with a history of atrial fibrillation (AF) who frequently attend the emergency department (ED) with symptoms may not require emergency treatment, and may be more appropriately managed in an alternative outpatient setting. This may be the result of inappropriate or inadequate advice or a lack of patient understanding. The main research objective pertains to the reason for seeking medical attention for AF in the ED, ED management of the patient, outcomes of ED care and alternative strategies.
The purpose of this study is to compare the effectiveness of prescribing oral anticoagulation therapy by pharmacist intervention compared to enhanced usual care in participants with unrecognized AF and/or known AF but not taking blood thinners.
Pharmacists are in the best position to counsel and educate patients on anticoagulant agents such as NOACs. This should enable patients to play a more active role in their treatment and ultimately enhance adherence behaviour. However, educational elements should be targeted to knowledge. Thus, the investigators will develop and validate a questionnaire that can assess knowledge about NOACs
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 permanent atrial fibrillation, by using imaging approaches, i.e. combined trans-esophageal and transthoracic echocardiography. The conducted LA-EU-01 study was a prospective, non-randomized, multi-center, open-label, non-comparative, interventional clinical investigation with the participation of two clinical centers in Germany and the inclusion of 61 subjects. Participating subjects were patients with non-valvular paroxymal, persistent or permanent atrial fibrillation with long-term sustainability and scheduled for interventional closure of the left atrial appendage who could not be treated with anticoagulation. After the procedure of implantation of the LAmbreTM Left Atrial Appendage Closure System, patients underwent a first follow up assessment prior to hospital discharge then at 30 days, 6 and 12 months.
To provide data demonstrating the safety and effectiveness of the Arctic Front Advance™ Cardiac CryoAblation Catheter for the treatment of recurrent symptomatic paroxysmal atrial fibrillation, without the requirement that the subjects be drug refractory.
The aim of our study is to investigate the comparative efficacy of high fidelity multi electrode ablation catheters vs the standard bipolar configuration in success of AV nodal ablation This study will provide insights on the use of new technology where application may increase efficacy, promote patient and physician safety and decrease costs.
Atrial fibrillation (AF) is a frequent heart rhythm disorder, responsible for the formation of cardiac thrombi, which can embolize in the systemic circulation, responsible for strokes (Cerebrovascular accidents). AF increases the risk of stroke and stroke-related disability. Preventing the thromboembolic risk associated with FMD is therefore a public health issue. The reference treatment is oral anticoagulation but this treatment is contraindicated in patients with a history of intracranial hemorrhage. The percutaneous closure of the auricle is a recent technique which makes it possible to exclude this appendix from the left atrium where the majority of thrombi are formed in the framework of the AF. Comparative studies have shown the effectiveness of this technique, appearing to be similar to that of anticoagulation. However, in view of the per-procedural risk, the indication of closure was retained by the health authorities only in the event of a contraindication to oral anticoagulants in patients with non-valvular AF with a high thromboembolic risk. Patients with a history of intracranial hemorrhage are therefore candidates for this technique, but there are few studies where these patients were included. The risk-benefit must be demonstrated over the long term, in terms of ischemic, hemorrhagic recurrence and becoming functional and cognitive.
This observational study evaluates peri-procedural results of the Niobe™ Remote Magnetic Navigation (RMN) ES system using the contact detection system (CDS) in patients undergoing standard of care radiofrequency ablation of cardiac arrhythmias. The objective of this observational study is to confirm system performance of the CDS and that it does not alter pacing, electrocardiograms, or mapping during RF ablation procedures.
This study is designed to evaluate the efficacy and safety of warfarin anticoagulation in the very old and attempt to identify risk factors which may impede safe and effective anticoagulation.
