Prevention of Postoperative Atrial Fibrillation (POAF) Using Intra-Pericardial Amiodarone
The purpose of this study is to evaluate the combination of CardiaMend, with the addition of amiodarone in the prevention of postoperative atrial fibrillation (POAF) in patients undergoing cardiac arterial bypass grafting (CABG) or valve surgery.
Exercise Training in Patients With Persistent or Permanent Atrial Fibrillation
The main purpose of this project is to evaluate the effects of high-intensity interval training (HIIT) compared to moderate-intensity continuous exercise training (MICE) and standard care on exercise capacity and quality of life in patients with persistent or permanent atrial fibrillation. Positive findings are vitally important for these patients, given …
DELTA (Detecting and Predicting Atrial Fibrillation in Post-Stroke Patients)
Atrial Fibrillation (AF) is an abnormal heart rhythm. Because AF is often asymptomatic, it often remains undiagnosed in the early stages. Anticoagulant therapy greatly reduces the risks of stroke in patients diagnosed with AF. However, diagnosis of AF requires long-term ambulatory monitoring procedures that are burdensome and/or expensive. Smart devices …
Personalized Atrial Fibrillation Ablation Guided by Non-Invasive Global Mapping
This pilot study investigates if non-invasive global mapping can guide catheter ablation of atrial fibrillation (AF) by defining personalized targets based on the temporal Stability of local Atrial High-Rate Activity (SAHRA). The study also assesses efficacy and safety of this approach and evaluates potential signals of harm. The main questions …
Reversal of Atrial Substrate to Prevent Atrial Fibrillation Cohort Study
Atrial fibrillation (AF) is a major health problem, with a prevalence of 0.4-1% of the population. It results in high healthcare costs and significant morbidity, especially for patients with severe symptoms. The RASTA-AF randomized control trial (RCT) is designed to answer the following question: does vigorous treatment of AF with …
Study of Atrial Fibrillation Combined with Atrial Functional Mitral Regurgitation
To evaluate the improvement of mitral regurgitation after catheter ablation of atrial fibrillation or regular drug therapy in atrial fibrillation patients combined with atrial functional mitral regurgitation.
Comparison of Different Pulsed Field Ablation Catheters in Atrial Fibrillation
Pulsed field energy ablation, a non-thermal ablation modality, can potentially reduce post-ablation tissue edema. Previous studies have confirmed the feasibility and safety of combined pulsed field ablation (PFA) and left atrial appendage closure (LAAC) as a one-stop treatment, with few reports of post-ablation tissue edema. However, during PFA procedures, the …
Effects of Music During Atrial Fibrillation Ablation Under Conscious Sedation
I. Background Atrial fibrillation, a common type of arrhythmia, is often treated with radiofrequency catheter ablation, a minimally invasive procedure that helps restore a normal heart rhythm. While this surgery is typically performed under "light sedation" (where patients remain semi-awake) and allows for quick recovery, many patients still experience significant …
Effect of Mechanical Ventilation on Radiofrequency Ablation in Atrial Fibrillation
Radiofrequency ablation (RFA) for atrial fibrillation (AF) is performed under general anesthesia. The success of the procedure depends on the safe contact of the catheter electrode with the myocardium. Movement of the catheter tip due to respiratory changes can result in inadequate lesion formation and AF recurrence. The success of …
Cardiac Assessment for Recurrent Stroke Risk Evaluation in Atrial Fibrillation
Background Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting up to 10% of the elderly. Ischemic stroke is the main complication of AF and cardioembolism is one of the leading causes of ischemic stroke, accounting for approximately one third of cases. Oral anticoagulant therapy (OAC) is a cornerstone …
