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.

One-in-four Canadians will be diagnosed with an abnormal heart rhythm called atrial fibrillation (AF) in their lifetime. This is expected to double by 2050, owing to an aging population and increased age- and health behaviour-associated AF risk factors (e.g., poor cardiorespiratory fitness, Type II diabetes, hypertension, and obesity). AF is associated with an increased risk of severe health outcomes including stroke, heart failure, dementia, and death. Nearly three-quarters of people with AF also have obesity (excess body weight). According to research, people with obesity that lose approximately 10% of their body weight can experience relief from uncomfortable AF symptoms. Losing weight may even help people return to a normal heart rhythm. Cardiac rehabilitation (CR) is a proven way to help people with heart disease live longer, healthier lives. So far, research has not shown whether CR helps improve the abnormal heart rhythms seen in AF. This may be because CR programs usually do not offer specific help with weight management. Therefore, adding behavioural weight-loss treatment (BWLT; group classes to change thoughts and behaviours to encourage weight loss) to CR programs may help people with AF and obesity experience relief from their symptoms. This randomized controlled trial will assess whether the combination of an AF-specific 'small changes' BWLT and traditional CR results in a greater proportion of patients with AF and obesity achieving ≥ 10% body weight loss compared to patients who receive standard care (traditional CR alone). Traditional CR consists of participating in exercise sessions, supervised by health professionals, twice per week for 12 weeks. In addition to traditional CR, patients that are randomized to receive BWLT will attend 12 weekly online group therapy classes to learn strategies from psychology to help encourage weight loss. The investigators will collect data pertaining to weight, AF burden, physical activity, and disease-specific and generic patient-reported outcomes. This information will determine if taking CR+BWLT helps patients with weight loss and AF symptoms. Further, it will help efforts to provide effective treatment to patients with AF to help participants lose weight and reduce or eliminate AF symptoms.

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.

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.

This study aims to investigate the effect of reducing ablation time for a hybrid approach of vHPSD and AI-guided ablation using the QDOT Micro catheter in PVI among patients with PAF.
