Filter by:This is a randomized controlled trial (RCT) to test a novel artificial intelligence (AI)-enabled electrocardiogram (ECG)-based screening tool for improving the diagnosis and management of Atrial Fibrillation.
This will be a prospective, single-blinded, three-center, randomized, controlled trial comparing the effectiveness and safety of angioplasty guidewire-assisted transseptal puncture (GW-TSP) technique to transseptal left atrial (LA) access with conventional transseptal puncture with standard transseptal equipment (CON-TSP) in patients undergoing left atrial appendage occlusion (LAAO) procedure for atrial fibrillation. The targeted population will consist of patients with atrial fibrillation undergoing LAAO.
This is a multi-center, 2-arm, assessor and statistician blinded, pilot randomized controlled trial, to evaluate the effect of catgut embedding in acupoints of Neiguan and Zusanli in reducing early recurrence and improving long-term prognosis in patients with persistent AF after CA..
Given both the increasing population impact of atrial fibrillation (AF) and the widespread consumption of coffee in society, determining an associated benefit or risk of coffee consumption on AF is of great clinical relevance. This pilot study will evaluate the effect of randomly assigning participants undergoing electrical cardioversion to coffee abstinence or coffee consumption over a 6 month period. This pilot study will provide the first, randomized evaluation of coffee on AF outcomes and will provide important information on whether or not coffee has any effect on AF recurrence.
This is a prospective, multicenter, randomized clinical evaluation of the Sphere-9 Mapping and Ablation Catheter with the Affera Mapping and Ablation System. Subjects will be randomly assigned 1:1 to receive treatment with either the Sphere-9 Mapping and Ablation Catheter and the Affera Mapping and Ablation System (investigational device) or the THERMOCOOL SMARTTOUCH® SF radiofrequency ablation catheter (control device).
Atrial fibrillation (AF) is associated with increased mortality and morbidity, and is a dominant, yet preventable, cause of cardioembolic stroke, which has more severe outcomes than other ischaemic stroke causes if left untreated. Approximately 10% of ischemic strokes are associated with AF (AF) first diagnosed at the time of stroke. Detecting asymptomatic AF would provide an opportunity to prevent these strokes by instituting appropriate anticoagulation. Early diagnosis of AF might enable oral anticoagulant therapy and prevent unwanted consequences of undetected disease, leading to the suggestion that screening for AF might be beneficial in populations at risk. However, there is still debate about whether screen-detected AF bears a similar stroke and mortality risk profile to clinically detected AF, particularly when AF screening is done at a higher intensity than single-time point. The absence of studies reporting on hard clinical endpoints in AF screening has led to differences in recommendations globally. Most notably, systematic screening for AF is to be considered according to 2020 European guidelines, whereas the US Preventive Services Task Force concluded that current evidence is insufficient to assess the balance of benefits and harms of screening for AF. The incidence of screen-detected AF strongly depends on the population screened and duration/intensity of screening. Single-time point screening of a general population ≥65 years of age detects undiagnosed AF in 1.4%, and the AF detected is largely persistent. In a large population-based study of individuals 75 to 76 years of age, a more intense 2-week screening program using twice-daily intermittent handheld ECG recordings identified AF in 3.0% (0.5% on the initial ECG4). The identical protocol restricted to those with ≥1 additional stroke risk factor identified 7.4% with AF. This study was designed in to two arms. The purpose of Arm 1 is to upgrade the artificial intelligence by collecting the continued ECG monitoring data in patients with previous diagnosed AF. The purpose of Arm 2 is to investigate the detection rate of AF using systematic, intensive AF screening with continuous ECG monitoring and the rate of clinical outcome in individuals at high risk during one year follow-up.
Being the most common arrhythmia, atrial fibrillation (AF) is a high burden of public health with an increasing prevalence in our aging population. Interventional treatment of atrial fibrillation by catheter ablation is one of the treatment pillars in the complex field of "better symptom control" based on current Guidelines. Catheter ablation of atrial fibrillation is based on electrical isolation of the pulmonary veins (pulmonary vein isolation: PVI) from the left atrium. The main benefit and goal of PVI in AF patients is the reduction of AF-related symptoms, resulting in an improvement of quality of life. It was shown, that catheter ablation failed to prove a difference in AF recurrence after PVI compared to medical therapy in the first 18 month of follow-up. It was also shown, that these episodes will become more asymptomatic. This raises concerns that the symptomatic improvement might be the result of a placebo effect, which will be elucidated with this study.
This is an extended follow up study of the original RAFT-AF Study. The RAFT-AF study was a multi-centre randomized controlled trial with a prospective randomized open blinded endpoint trial (PROBE) design. Patients were randomized to either catheter ablation-based rhythm control of AF as compared to rate control of AF
Pulmonary vein isolation (PVI) is the cornerstone of ablation for atrial fibrillation (AF). Increased cardiac sympathetic stimulation can facilitate AF and reduction can be accomplished by renal artery denervation (RDN). The recently completed randomized trial, ERADICATE-AF, convincingly demonstrated that RDN plus PVI resulted in a reduction in recurrent incident AF for uncontrolled hypertensives. This is a randomized controlled pilot trial, "To Evaluate Renal Artery Denervation in Addition to Catheter Ablation to Eliminate Atrial Fibrillation" (ERADICATE-AF II) to test if RDN plus PVI enhances long-term efficacy vs PVI for persistent AF patients with controlled or without hypertension using implantable loop recordings.
The PROVECT study is a retrospective, multicentre study assessing the effectiveness and the safety outcomes in patients with non-valvular atrial fibrillation (NVAF) treated by apixaban between 2015 and 2019 (5 years follow up). The study will use harmonized and federated hospital electronic health records (EHRs) from 10 Belgian hospitals. Outcomes of interest are major bleeding events leading to hospitalization (safety), stroke and systemic thromboembolic events (effectiveness), and all-cause mortality (as an exploratory endpoint, and after confirming the data availability because the death events are not always recorded into hospital EHRs). The study will analyse the outcomes by patient characteristics including the age groups focusing on elderly, thromboembolism risk factors (CHAR2RDSR2R-VASc score), bleeding risk factors (HAS-BLED score), comorbidities (Deyo-Charlson Comorbidity Index, DCCI) score and frailty.
