Atrial Fibrillation in Young Patients: a Prospective Multicentre Registry
Atrial fibrillation is a rare cardiac arrhythmia in young (i.e. <= 35-year-old) patients. Etiological factors, current management and mid- to long-term outcomes remain unknown.
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 …
Prospective Phenotyping for Genetic Subtypes of Early-onset Atrial Fibrillation
This is a prospective, case-control study that seeks to learn about the role of genetics in early onset atrial fibrillation (AF) and if genetic testing can be used to improve how the investigators treat atrial fibrillation. The study will enroll 225 participants. Eligible participants will have undergone sequencing for arrhythmia …
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 …
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 …
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.
Implantable Cardiac Monitor to Detect Atrial Fibrillation in Patients With MINOCA
Myocardial infarction with non-obstructive coronary arteries (MINOCA) (i.e.<50% stenoses) on coronary angiography) is an underappreciated clinical entity concerning 5-6% of patients with acute myocardial infarction. Approximately 50% of these patients remain without appropriate diagnosis and treatment. The MINOCA study aims at systematically assessing the frequency of underlying pathologies of MINOCA …
Contribution of Computed Tomography and Cardiac-MRI in Atrial Fibrillation Ablation
Atrial fibrillation ablation (AF) is a standard interventional treatment for patients with symptomatic AF refractory to medical treatment. The known predictive factors for the success of the procedure remain insufficient to predict the probabilities of success and to appropriately select the patients who could benefit the most from this procedure. …
Prospective Database for Prediction of Atrial Fibrillation in Pacemaker and ICD Patients
Atrial fibrillation (AF) is associated with a five-fold increased risk of cerebrovascular stroke. While the risk of stroke in patients with known AF can be calculated via AF stroke prediction risk scores, the prediction of AF occurrence per se in individual patients remains difficult. We will recruit 250 patients with …
Application Value of Whole-procedure Optimization for Catheter Ablation of Atrial Fibrillation
The success rate of single-procedure atrial arrhythmia-free survival particularly ranged from 40% to 66% in persistent AF ablation. However, The surgical Cox maze III procedure has been established to be an effective curative strategy for AF with an AF-free survival rate of more than 95%. The main reason is the …
