Change in Inflammatory State in Patients Undergoing Transcatheter Ablation of Atrial Fibrillation
It is a non-pharmacological (biological), spontaneous observational study. The main objective is to evaluate the correlation between inflammation markers and local adiposity, clinical risk factors and their possible variation following an AF ablation procedure
Prospective Cohort Study of the Risk of Recurrent Atrial Fibrillation After Radiofrequency Ablation
In this study, the continuous inclusion of atrial fibrillation patients treated by catheter ablation in the Department of Cardiology, Peking University Third Hospital, through the collection of clinical data and outpatient follow-up, to explore the risk factors of atrial fibrillation recurrence after catheter ablation and the influencing factors of major …
Defining the Risk of Ventricular Tachycardia in Genetic Forms of Early-onset Atrial Fibrillation
To use programmed ventricular stimulation at the time of AF ablation to define the prevalence and mechanism of inducible ventricular tachycardia (VT); pace-mapping to define the site of origin of ventricular arrhythmias; and voltage mapping to define low voltage scar substrate in the basal LV in patients with pathogenic TTN …
Association Between GalectiN-3 and POSt-operative AtrIal Fibrillation After Coronary Artery BypaSs Graft
The goal of this observational study is to test the association between high levels of Galectin-3 and the occurrence of post-operative atrial fibrillation after isolated coronary artery bypass grafting (CABG). The main question[s] it aims to answer are: Is Galectin-3 an accurate biomarker to predict higher risk of developing post-operative …
Baseline Atrial Fibrosis Predicts Risk for Post-operative Atrial Fibrillation in Patients Undergoing Cardiac Surgery
The study aims to evaluate and compare the incidence of atrial arrhythmias (including Post-Operative Atrial Fibrillation (POAF), atrial flutter, and atrial tachycardia) stratified by baseline Utah fibrosis stages and overall fibrosis (%) of the left atrial wall area. The investigators hypothesize that patients with a higher baseline Utah fibrosis staging …
AFLETES-MRI: A Cardiac and Cerebral Magnetic Resonance Imaging Study in Athletes With Atrial Fibrillation
Participation in exercise improves cardiovascular health. However, long-term endurance exercise may increase the risk of an irregular heart rhythm called atrial fibrillation (AF). In AF, blood flow is altered, increasing the risk of clot formation in the heart which may enter the circulation and cause a stroke. The risk of …
Comparison of Different Ablation Surgeries on Left Atrial Reverse Remodeling in Patients With Atrial Fibrillation
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 …
Impact of Inflammatory Indexes and Gene Scores in Prediction of Atrial Fibrillation Recurrence Following Electrical Cardioversion
Because of the high recurrence rates following electrical cardioversion and high morbidity in AF patients there is a need to explore prediction models for AF recurrence following ECV. Previous studies have primarily focused on high-sensitivity CRP (hsCRP), CRP, and IL-6, while other inflammatory indexes and gene scores might hold greater …
Safety and Efficacy of the CoolCryo System for Cardiac Cryoablation in the Treatment of Atrial Fibrillation
The study involves endocardial cryoablation of the left and/or right atrium of the heart using the CoolCryo system as an adjunct to mitral valve surgery, with the aim of eliminating atrial fibrillation (AF), which is a common sequelae of mitral valve defects and is associated with an increased risk of …
Left Atrial Volume Changes Who Underwent Cardioversion and Recurrence of AF After RF Ablation in Persistent AF (SAFE-AF)
Electrical/pharmacological cardioversion improves structural remodeling of left atrium. We hypothesize that persistent atrial fibrillation (AF) patients with more significant left atrial size reduction after cardioversion have lower AF recurrence rates following radiofrequency ablation. The aim is to evaluate the relationship between changes in left atrial size 3 to 6 months …
