Active clinical trials for "Atrial Fibrillation"

After cardiac surgery, there is a high prevalence of postoperative atrial fibrillation (POAF). However, its diagnostic and therapeutic management is poorly codified. This pathology is caused by atrial abnormalities which form the concept of atrial cardiomyopathy. New tools affording to itemize the atrial cardiomyopathy are needed. Indeed, current tools, as echocardiography and electrocardiogram are relevant but only lead to a raw evaluation of the atrial cardiomyopathy. MRI, because of the assessment of the atrial fibrosis by late gadolinium assessment (LGE) and 4D flow magnetic resonance imaging (MRI) could be relevant to specify the atrial cardiomyopathy.

The purpose of this study is to predict the occurrence of paroxysmal atrial fibrillation by finding high-risk group from normal sinus rhythm ECG through artificial intelligence-based prediction algorithm.

The purpose of this study is to determine whether cardiac resynchronization therapy (CRT) is superior to interventricular right ventricle (RV) septal pacing in respect of reverse remodeling (LV ESD) and morbidity in patients with less preserved (less than 45%) ejection fraction (EF), persistent/permanent atrial fibrillation (AF) who successfully received atrioventricular (AV) junction ablation ablation (100% pacemaker dependency)

The objective of this study is to determine whether early radiofrequency (RF) ablation treatment, using the CARTO® 3 or CARTO® XP System, and THERMOCOOL® Catheter Family (including THERMOCOOL® SF or THERMOCOOL® SMARTTOUCH™) in subjects with paroxysmal atrial fibrillation (PAF), delays progression of atrial fibrillation (AF) compared with drug therapy (either rate or rhythm control) using current AF management guidelines.

The investigators aim to investigate the immediate success rate (rate of termination of atrial fibrillation) of dual shock cardioversion compared with standard single shock cardioversion in patients with baseline characteristics adversely influencing successful cardioversion. Baseline characteristics known to reduce the success rate of single shock cardioversion include: increased body mass index (BMI), chronic obstructive pulmonary disease, sleep apnea, enlarged left atrium, longer duration of atrial fibrillation and use of amiodarone.

Atrial fibrillation (AF) is common, increases the risk of mortality, stroke and heart failure, and portending significant burden to patients, societal health and health economy. One of three AF cases are undiagnosed. Several methods for detection of AF exist, but most of them have major limitations and are associated with resource-demanding diagnostic workup in the speciality health care services. This randomized clinical trial will evaluate whether self-screening for AF with the ECG247 patch monitor will reduce AF-related morbidity.

This trial aims at evaluating the number of thromboembolic events post cardioversion in patients receiving a direct current cardioversion with either prior transesophageal echocardiography or D-Dimer (DD) analysis. Patients in need of a direct current cardioversion (DCCV), meeting the criteria for DCCV with prior transesophageal echocardiography (TEE), will be asked to participate in the CARDDI-BEL study. Patients will be randomized on a 1:1 ratio to the TEE-group or DD-group. Patients in the TEE-group will receive TEE prior to cardioversion to exclude left atrial thrombus according to current guidelines [1]. In patients randomized to the DD-group, D-Dimer will be analyzed (cut-off defined by DDage). If the DDage > 10x patient's age, the analysis is suggestive for the presence of left atrial thrombus and the cardioversion will be performed with prior TEE. In case of negative DDage, no TEE will be used in the DD-group.

AF is the most common sustained arrhythmia in adults and its prevalence increases with advancing age. In this study, we aim to determine whether the published genome-wide polygenic scores for atrial fibrillation (GPSAF) can facilitate AF screening by accurately discriminating between patients with low and high risk for AF. All included patients are participating in the MHI biobank, an ongoing funded institutional DNA bank and clinical registry approved by the research ethics board where included patients consent for future genetic research. The study will compare AF detection rate using a 3 months near continuous monitoring in individuals with a high GPSAF with matched individuals from the bottom GPSAF.

In this prospective, single-center, open-label, non-randomized, single- arm, historically controlled study, we will compare the detection rate of paroxysmal atrial fibrillation in acute ischemic stroke patients without known atrial fibrillation, using 14-day continuous electrocardiography patch monitoring, with a historical control group of patients who received serial 12-lead electrocardiograms once daily for five days or conventional 24-hour Holter monitoring. The study will be conducted in Chang Gung Memorial Hospital at Chiayi, Taiwan, from February 2022 to December 2024.

In elderly atrial fibrillation (AF) patients, AF is usually a manifestation of risk factors and comorbidities not only limited to cardiovascular diseases. Especially in elderly often more than two comorbidities are present. The presence of comorbidities also affects outcomes in AF patients. Current healthcare systems are single-disease focused, which increases the risk of underdiagnosing, replicating diagnostic tests and adverse drug-drug interactions, placing a high burden on healthcare costs. Healthcare systems and hospitals are in need of new care pathways to address the complexity of multimorbid AF patients and to reduce costs. The EHRA-PATHS consortium set out to address this need for change in management for multimorbid, elderly AF patients in Europe through the development of new care pathways. The aim of this study is to evaluate the current management of risk factors and comorbidities, and subsequently implement the newly developed care pathways and evaluate if these pathways lead to better management of risk factors and comorbidities in multimorbid, elderly AF patients, compared to current standard care.
