Active clinical trials for "Atrial Fibrillation"

In patients with persistent AF (PsAF), ablation limited to pulmonary vein (PV) isolation is the most straightforward approach, but results only in 50% of arrhythmia freedom at 1 year 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 systematically targeted so far, probably because of the absence of dedicated tools to make its ablation simple and easy. We sought to investigate the use of a specific catheter for visualization and ethanolization of vein of Marshall allowing to systematically include this target in the ablation set. The main objective of this study is to demonstrate the feasibility to use the Targeted Endovascular Delivery (TED) catheter specifically for visualization and ethanolization of vein of Marshall.

The goal of this study is to determine the effectiveness of a direct-to-patient virtual education program ("AF at Home") for adults with atrial fibrillation (AF). The main questions this study aims to answer are: Will participants in the educational program have improvement in quality of life, self-monitoring, and self-management strategies after program completion? Will patient level quality of AF care improve for participants in the educational program? Participants will be asked to: Participate in six hours of virtual education sessions over three weeks via Zoom. Complete online questionnaires before the program starts and after its completion.

The goal of this study is to determine the effectiveness of a direct-to-provider virtual education program ("AF and EKG Interpretation Project ECHO") for primary care providers who manage patients with atrial fibrillation (AF). The main questions this study aims to answer are: Will participants have improvement in knowledge and confidence in managing patients with atrial fibrillation after program completion? Will quality and performance metrics improve at the patient level for program participants? Participants will be asked to: Participate in 12 hours of virtual education sessions over twelve weeks via Zoom. Complete a knowledge and confidence assessment online before the program starts and after its completion.

This pragmatic clinical trial embedded in an accountable care organization will determine the comparative effectiveness of two approaches for assigning care coordinators to older adults at risk for cardiovascular outcomes. The hypothesis is that assigning care coordinators to older adults based on perceived need will be more effective at preventing emergency department visits and hospitalizations compared to usual care.

The AcQForce AF-EU clinical study is a prospective, multi-center, non-randomized global clinical study designed to demonstrate the safety and performance of the AcQBlate Force Sensing System.

This study is a mulitcentre, randomized, parallel-group evaluation of pulse field ablation(PFA) and radiofrequency ablation(RFA) in patients being treated for symptomatic paroxysmal AF. Pulmonary-vein isolation (PVI) is the primary intention of catheter ablation in both groups.

A prospective single blinded (subject blinded) 1:1:1 randomised control trial with three parallel arms testing superiority of analgosedation regimen based on remimazolam and total intravenous anesthesia over propofol based analgosedation. The primary composite endpoint consists of hypoxaemia, hypotension, or hypertension requiring intervention.

The main aim of the research is to investigate whether patients undergoing pulmonary vein isolation with catheter ablation for persistent atrial fibrillation (AF) will have lower rates of AF recurrence than those treated by DC cardioversion without an ablation procedure.

Several well conducted randomized controlled trials have established the superiority or non-inferiority of oral anticoagulants (OACs) compared with vitamin K antagonists to treat non valvular atrial fibrillation (AF) for the prevention of thromboembolic events, as well as their safety profile (less major bleeding events with OACs) in the general population. Atrial fibrillation is associated with higher morbidity and mortality in patients with ESKD but there is a lack of randomized data in ESKD on hemodialysis and no data on peritoneal dialysis. Therefore, available evidence comes from retrospective observational studies that are notoriously unreliable to estimate treatment effects. In the population of patients with end stage renal disease (ESRD) on peritoneal dialysis, the investigators hypothesize that apixaban will be safer and as effective than warfarin for the management of non valvular AF, with a robust methodology: a randomized controlled trial. Individually, if the study hypothesis is confirmed during this protocol, the benefit could be direct in the experimental arm with less bleeding than in standard-of-care arm. Moreover, the risk of bleeding with apixaban will be reduced with the use of concordant dosing in peritoneal dialysis condition, known from APIDP1 study. Collectively, the investigators hope for an improvement in scientific knowledge that will allow us to optimize the treatment of atrial fibrillation in subjects on peritoneal dialysis, maybe with the help of pharmacodynamics indicator.

This is a prospective, multicenter, observational study intended to characterize real-world outcomes on the commercially available Amulet device in the United States. The study will enroll approximately 1000 subjects at up to 50 US clinical sites. Subjects will be followed through 24 months in accordance with each site's standard care practices.
