Filter by:This study hypothesize that injecting calcium chloride (CaCl2) into the major atrial ganglionated plexus (GPs) during on pump Coronary artery bypass graft (CABG) can reduce the incidence of Post operative Atrial fibrillation in the first 7 days after surgery.The study is designed to be prospective interventional study two armed RCT for on pump CABG patient. The intervention arm will be injected with Calcium chloride in the four major atrial ganglionic plexus The control arm will be injected with sodium chloride to determine the effect of Calcium chloride on Post CABG Atrial fibrillation
This is a prospective, randomized controlled, single-blind, multi-center clinical trial study aiming to investigate whether the strategy of posterior wall isolation (PWI) assisted by vein of Marshall ethanol infusion (VOMEI) could improve the success rate of persistent atrial fibrillation ablation.
Despite a clear definition in the European Society of Cardiology (ESC) guidelines, the differentiation between paroxysmal (self-terminating) and persistent (nonself- terminating) atrial fibrillation (AF) remains challenging in clinical practice. Some patients with presumed persistent AF are planned for electrical cardioversion (ECV) but appear to have a paroxysmal pattern or present in sinus rhythm (SR) at the scheduled ECV appointment. This results in unnecessary visits or interventions for patients, and costs and burden for the hospitals and health insurances. Based on the feasibility of the TeleCheck-AF approach, which is an on-demand mobile health (mHealth) infrastructure incorporating app-based heart rate and rhythm monitoring to support remote AF management through teleconsultation, the investigators aim to extend this mHealth approach to the management of presumed persistent AF patients planned for ECV.
Observational, multi-center, retrospective study to evaluate the use of ICM (implantable cardiac monitor) versus traditional, non-ICM (non-implantable cardiac monitor) methods such as ECGs (electrocardiogram), Holter, and mobile cardiac outpatient telemetry (MCOT) units.
All consecutive patients with paroxysmal or persistent atrial fibrillation undergoing pulmonary vein isolation with the radiofrequency balloon catheter (RFB) "Heliostar" (Biosense Webster) will be included in a multicenter observational registry. The aim of the study is to assess the safety and arrhythmic outcome of atrial fibrillation ablation with the RFB in a real-world setting.
The goal of this observational study is to evaluate the clinical characteristics of patients undergoing permanent cardiac pacing and to compare procedural efficacy and safety of different implantation approaches in the clinical practice of the participating centres. The contribution of non-fluoroscopic anatomical and electrophysiological reconstruction systems to device implantation procedures will also be evaluated. Participants [patients over 18 years old with an indication to receive a definitive pacemaker/intracardiac defibrillator implant] will receive a permanent cardiac pacing implant as requested according to European Society of Cardiology (ESC) guidelines; the investigators will evaluate procedural efficacy and safety of different implantation approaches.
Observational, multi-center, non-randomized, post-market study. This is a nested sub-study of the REAL AF Registry. Consecutive symptomatic drug refractory paroxysmal atrial fibrillation (PAF) patients from the registry will be screened for enrollment to this sub-study per inclusion and exclusion criteria.
Therapeutic management of Atrial Fibrillation (AF) is based either on heart rate control or on rhythm control, a strategy which aims to maintain a normal heart rhythm. The benefit in terms of morbidity and mortality of a normal heart rhythm would, however, be largely offset by the frequent side effects of antiarrhythmic drugs which could even lead to an increase in mortality compared to rate control. This increase has particularly been suggested in people aged over 75. Since the emergence of catheter Pulmonary Vein Isolation (PVI), an effective alternative to antiarrhythmic drugs has become available. This technique makes it possible to isolate the foci triggering AF under local or general anesthesia with greater effectiveness than medications and very low risks. Records in the elderly do not seem to show a reduction in effectiveness or an increase in complications. However, in the absence of a dedicated randomized study, its use is strongly limited in the elderly where rate control (52% of people over 65 years old) and the use of antiarrhythmic drugs are largely favored due to the simplicity of implementation and the low cost of medications. However, an early rhythm control strategy seems to reduce cardiovascular events in relatively old individuals (average age 70 years). The use of PVI in first line could make it possible to further improve these results. The objective of the investigator is therefore to carry out the first randomized comparative study proposing to evaluate the impact of early PVI compared to usual treatment in patients aged 75 and over with AF.
The goal of this Ambispective cohort Study is to compare in patients with paroxysmal atrial fibrillation undergo pulse field ablation and radiofrequency ablation, respectively. The main question it aims to answer are:Comparison of the therapeutic effects of pulse field ablation and traditional thermal ablation on patients with paroxysmal atrial fibrillation and postoperative left atrial reverse remodeling.Participants will Perform pulse field ablation or radiofrequency ablation according to different groups, and cooperate to complete outpatient follow-up 6 months after surgery.
Antecedents: electrical isolation of pulmonary veins is the standard treatment for patients with atrial fibrillation. However, its efficacy is lower in persistent and chronic forms of this arrhythmia compared to paroxysmal atrial fibrillation. Many complementary techniques have been proposed, that added to pulmonary veins isolation, may reduce the recurrence rate of atrial fibrillation. However, none of them has obtained consistent results. Linear ablation aims to parcellate and modify the left atrial substrate responsible for atrial fibrillation maintenance. Previous studies have offered contradictory results using linear ablation. Methods: SUPAFER is a multicenter, 1:1 randomized clinical trial that compares the efficacy of pulmonary veins isolation alone vs pulmonary vein isolation plus an specific protocol of left atrial linear ablation. Contrary to previous studies, the specific SUPAFER linear ablation is systematic, homogeneous and target atrial areas that have not been systematically ablated in previous trials. The trial aims at demonstrating the superiority of the combined ablative approach during 1-year follow-up. Daily transtelephonic ECG samples a 30 days continuous ECG monitoring are used to maximize de detection of recurrences, even asymptomatic.
