View clinical trials related to Atrial Fibrillation.
Filter by:A prospective, non-randomized, multi-center clinical trial. The patient population includes patients with permanent or persistent AF requiring valve replacements or repairs, ASD repairs, PFO closure or coronary artery bypass grafts (CABG) procedures. Patients are not allowed to have had previous atrial ablation, AV-nodal ablation, or surgical Maze procedure.
The aim of FINACAF study is to evaluate the incidence and risk of stroke, systemic thromboembolic events, myocardial infarction, major bleeding events, and mortality in relation to different attitudes regarding stroke prevention treatment among AF patients. The study with cohort design is conducted as a nationwide retrospective register-based linkage study using data obtained from the Finnish health care registers.
This is a randomized controlled trial examining whether Baylis's Versacross RF wire versus the conventional Baylis RF needle is better at puncturing through a thin wall in the heart (called "transseptal puncture") as measured by time to successful transseptal puncture, during cardiac ablation procedures.
Context Atrial fibrillation is the most frequent arrhythmia following coronary artery bypass grafting. POAF is associated with worse outcomes following CABG. In addition, recurrence of AF is associated with longer hospital stay and higher rate of neurological and renal complications compared to a single episode of AF Objective To estimate the proportion of eligible people who are willing to participate, number of participants who drop out of the trial and use the results of this study to inform a larger study. Study Design: Pilot randomized controlled trial. Patients will be blinded to the intervention. Participants: The study population will include 40 patients. Patients admitted to the Jewish General Hospital for elective coronary artery bypass grafting from May 2021 will be included in the study. Patients will be included if they were in sinus rhythm with a HR ≥50 bpm, undergoing on-pump coronary artery bypass grafting and hemodynamically stable. Patients will be excluded from the study if they meet any of the following criteria: Second or third degree heart block, LVEF <35%, left atrial volume index ≥42 ml/m2, right atrial volume index > 47 ml/m2, any degree of tricuspid regurgitation, any degree of right ventricular dysfunction, emergency or minimally invasive operation, concurrent valve operation, history of atrial fibrillation or previous cardiac surgery Study Interventions and Measures Patients will be randomly assigned to one of two treatment groups according to the venous cannulation technique used during surgery. Group A will undergo cavoatrial cannulation with a 2-stage venous cannula. Group B will undergo bicaval cannulation with snares. Similar surgical methods will be used in all treatment groups . The primary endpoint will be defined as any episode of atrial fibrillation in any participant lasting >5 minutes in duration or any episode leading to hemodynamic compromise (SBP<90 mmHg) or causing symptoms (angina or dyspnea). Atrial fibrillation will be diagnosed using telemetry and a 12-lead ECG. Patients will be followed up in 1 month with a 12-lead ECG to determine their rhythm. The secondary endpoints are the development of RV dysfunction, tricuspid regurgitation and any increase in left atrial volume index as detected by post-operative transthoracic echocardiography.
Primary objective: To compare the safety and efficacy of closure strategies post venous access procedures. Hypothesis: We anticipate that the use of a venous closure device will decrease the time to hemostasis (TTH), time to ambulation (TTA) and time to discharge (TTD) compared to conventional methods of closure following venous access procedure.
Postoperative atrial fibrillation (POAF) is a common complication that occurs in 30-50% of patients after cardiac surgery and increases morbidity and mortality and hospital length of stay. During the perioperative period, the discontinuation of beta-blocker treatment is known to be a risk factor for developing POAF in patient undergoing cardiac surgery. Early beta-blocker reintroduction is associated with lower incidence of POAF. Unfortunately, side effects of currently available beta-blockers (including esmolol), such as low blood pressure and excessive bradycardia and/or their extended duration of action, limit their use in the post-operative period especially for prevention. Landiolol, an ultra-short acting injectable beta-blocker, offers the advantage of significantly limiting low blood pressure events while increasing therapeutic efficacy in the treatment of POAF in cardiac and non-cardiac surgery. Landiolol, when used at low dose in the postoperative period, has been showed to reduce the incidence of POAF with no increased incidence of side effect as compared to standard of care. The limitation is that these promising data come from single center studies with limited samples and conducted exclusively in Japanese population. If landiolol is approved for use in the treatment of atrial fibrillation in non-Asian patients, there are no data on the prevention of POAF in cardiac surgery. The objective of this multicenter, double-blind, randomized, placebo- controlled phase III trial is to confirm that landiolol postoperative infusion is associated with lower incidence of POAF without excess of adverse events as compared to standard of care in a non-Asian population after cardiac surgery with sternotomy.
This is a national, multi-center, prospective study to evaluate the safety of Edoxaban in patients diagnosed with AF who are currently using Edoxaban for stroke prevention. The primary objective: - To evaluate safety of Edoxaban treatment in patients with atrial fibrillation (AF) on Edoxaban therapy in routine clinical practice in Turkey.
Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
